Abstract: Disclosed are a method, apparatus and system for providing action selections to an image referencing a product in a video production and a content reference architecture beneficially used therewith. According to the disclosure a method for providing action selections to an image referencing a product in a video production includes (1) communicating a video production to a reproducing apparatus, the video production comprising a placement zone and a trigger zone at least partially coincident with the placement zone, wherein the trigger zone comprises a trigger resource identifier, and wherein the placement zone comprises an image referencing a product; (2) communicating to the reproducing apparatus an indication that an action selection interface associated with the product is available in response to a request corresponding to the trigger; and (3) communicating to the reproducing apparatus a characterization of the action selection interface, wherein the action selection interface comprises a selectable action. A disclosed method includes receiving a first request (URI) from a reproducing apparatus, for example a set-top box, the first request having been extracted from a video production communicated to the reproducing apparatus; determining a second resource identifier (URL) responsive to the first request and redirecting the first request wherein a response is provided to the reproducing apparatus.

Description: SYSTEM ALLOWING SELECTION OF PRODUCTS IN A VIDEO PRODUCTION BY USING REFERENCE IMAGES BACKGROUND FIELD The invention relates generally to enhanced video more particularly to video operable with networked action resources and also to the handling of resource identifiers used in connection with enhanced video. BACKGROUND Enhanced Video including Enhanced Television involves a developing set of technologies directed towards providing viewers rich and customizable interaction options in connection with elements of a video production. Conventional means of providing the enhancing interactive content involve integrated devices capable of receiving and reproducing the video production and of interactive communications with resources available over a data network. Purveyors of products generally wish to make information relating to their products available to prospective purchasers. It is particularly desirable to provide interactive information about a product. Interactive information allows a prospective purchaser to better receive desired information about a product, participate in interactive events respecting the product, and, of course, purchase the product. Typically interactive information also provided the added convenience to prospective purchasers of not having to transcribe access information in connection with product purchases. At a minimum, however, purveyors of products frequently wish to make an image referencing their product present in a video production. It is frequently desired that the purveyor be able to select appropriate contexts in the video production for display of an image referencing their product in order develop or maintain the distinctive quality of the image referencing their product(s) and promote contextually-driven positive associations with their product(s). Both qualitative and quantitative factors are frequently contextually relevant. Conventionally, purveyors of products arrange with authors of a video production to include a "product placement" in the video production. However, conventional product placements are unable to support interactive behavior. A related technique for providing interactive behavior in a video production is to display a locator for a networked resource in a video production as is described, for example, in U.S. Patent 5,774,666 issued to Portuesi. Techniques similar to this may not provide a desired level of consumer acceptance in practice. Display of a locator for a networked reference may unnecessarily clutter a viewer's display. In addition, the locator may be unrecognizable by a viewer as being associated with any particular subject matter displayed on the viewer's display because of the frequently lengthy and confusing syntax of uniform network resource locators. A variation of this technique is to use so-called "hot spots." However this, too, only provides active regions on a display and a viewer may need to consult the uniform network resource locator displayed when the hot spot is active which, again, are frequently lengthy and confusing to understand, and needlessly distracting. Rather it would be desirable to have a solution in which images easily recognizable by a viewer as referencing a product could be used. Another conventional solution is to provide a video production dedicated to providing information about a product. This solution may be unsatisfactory for several reasons. First it may be excessively costly. Creation of the video production dedicated to providing information about a product requires all the costs incurred in producing any video production which will be far beyond the resources of many vendors. Furthermore, when as brief as a conventional commercial, it is of insufficient duration to support rich or involved interactive features which may be a necessity to effectively compete in the marketplace. Second, this solution is frequently deficient in reaching a wide audience of prospective purchasers. Typically, the audience of the video production dedicated to providing information about a product is limited to a small segment of the potential market for who the opportunity cost of viewing the dedicated video production is quite low. By contrast, video productions of primarily entertainment value can draw large audiences. Third, there is limited availability for commercially desirable broadcasting times for a video production dedicated to providing information about a product as the commercially desirable broadcasting times conventionally are reserved for video productions of primarily entertainment value. Using conventional interactive television techniques with the video production dedicated to providing information about a product cannot eliminate these drawbacks. It is therefore desirable that a system and method exist that allows interactive product behavior to be provided to an image referencing a product in a video production, that provides purveyors with the flexibility to select contextually appropriate segments of a video production for interactive behavior, that operates with images referencing products and other symbols easily recognizable by a viewer, that is cost effective, and that operates with video productions of the type conventionally found in commercially desirable time slots. Given the high rate of television ownership, consumer familiarity with, and appreciation of, television, conventional Enhanced Video solutions frequently operate with widely used television broadcast signals. Such solutions typically involve encoding one or more resource identifiers into non-viewed portions of the television broadcast signals. The resource identifiers are then extracted by an integrated device which then presents to the viewer in some manner the option of interacting with enhancing resources available via the resource identifier. Frequently, the resource identifiers are encoded in the vertical blanking interval ("VBI") of a television broadcast signal. An industry standard provided from the Electronic Industries Association ("EIA") of Arlington, VA, U.S.A. defines a system for the transport of internet Uniform Resource Locator ("URL") information using the Text-2 service of line 21 of the VBI. The EIA standard syntax provides that the general format for transport of URL information in the VBI is to provide the URL followed by zero or more pairs of attributes and values which is then followed by a checksum. The EIA standard further indicates that, in order to preserve sufficient bandwidth for other services that use line 21 of the VBI, URL information should be limited. Limitation on URL information can be inconvenient. While resource identifiers, including URLs, can be compact, it may be desirable that they be quite lengthy. For example, GET-based forms in compliance with the Hypertext Transfer Protocol ("HTTP") commonly involve URLs that are quite lengthy. It may also be desirable to include numerous parameter- parameter value pairs in a resource identifier to provide greater customization of interactions. It is therefore desirable that a solution exist that allows enhancing content customization through use of lengthy or parameterized resource identifiers without consuming limited bandwidth in a video production. Another problem that arises in connection with Enhanced Video is synchronization of the content of the video production with the enhancing content. This may take on many forms. Some examples are created by the passage of time between creation of the video production and the time when enhancing interaction is desired. For example, a television program may be originally created with encoded resource identifiers to enhancing content relating to a promotion for the latest model of a vendor's product. After the passage of time, for example when the program were broadcast again as a re-run the following year, the resource identifier may no longer address the vendor's latest product because newer versions may have been released during the intervening time period. The same type of problem can arise in the context of an instructional video production. For example, the originally created encoded resource identifiers may address the scholarship, regulations, or additional instructional content appropriate at the time the video production was created. However after the passage of time, these same resource identifiers could provide enhancing content that was misleading. It would thus be advantageous that a solution exist that allows for time- appropriate enhancing content to be provided in connection with an enhanced video production. A different time-related synchronization problem that may arise in connection with Enhanced Video stems from an inability to provide resource identifiers to appropriate enhancing content by the time for broadcast of the video production; for example, a live video feed from a sporting or news event. As the event unfolds, opportunities may arise where it would be desirable to provide enhancing content. However, it is may be impossible to predict all contingencies for which it would be desirable to provide opportunistic enhancing content. For example, during a baseball game a triple play may occur and it may be desirable to provide enhancing content about other triple plays, statistics, and the like which are available in data storage of the broadcaster or an affiliated entity. However, it would impractical or burdensome to provide resource identifiers directly to these resources. Accordingly, it would be beneficial that a solution exist that allows for opporuntistic provision of enhancing content. Yet another problem that may arise in connection with Enhanced Video is that of appropriate internationalization. Video events frequently draw international audiences, for example, Olympic and other sporting competitions, space exploration, and international conflicts. The author or publisher of video productions of such events may desire to provide distinct enhancing content for different national, or linguistic groups. However it may be inconvenient or impossible to provide separate resource identifiers in the video production for each group. Therefore it would be favorable for a solution to exist that facilitates internationalization of enhancing content. In connection with Enhanced Video, it is further desirable that a method and system exist for providing resource identifiers to support an enhanced video production in advance of having any enhancing content and/or in advance of an arrangement that a particular entity will provide enhancing content. For example, an author of a video production may desire to generate revenue by, for example, selling the rights to provide enhancing content in connection with one or more particular resource identifiers. Such an author would desire a method and system that would allow the author to embed resource identifiers in the author's video production in a manner that would allow the author (or other entity holding appropriate rights) to sell the rights to provide enhancing content to one or several parties after creation of the video production. Conventional methods are unable to provide a solution to such an author in that typical resource identifiers specify a path that is dependent on the particular content associated with the resource identifier. Conventional redirection is also unable to provide a solution to such an author because the author may sell the rights to provide enhancing content to several different entities. Each of the several different entities would typically desire to have requests for enhancing content initiated in response to selection of a resource identifier for which the entity owned the right to provide enhancing content directed to the entity's server; conventional redirection is unable to provide a solution to this type of problem. SUMMARY In order to provide these and other desired features, the instant invention provides a method and system for providing action selections to an image referencing a product in a video production and a content reference architecture that may beneficially used therewith. A illustrative method in accordance with the invention may include: communicating a video production to a reproducing apparatus, the video production including a placement zone and a trigger zone at least partially coincident with the placement zone, wherein the trigger zone includes, at least, a trigger resource identifier, and wherein the placement zone includes an image referencing a product; communicating to the reproducing apparatus an indication that an action selection interface associated with the product is available in response to a request corresponding to the trigger; and communicating to the reproducing apparatus a characterization of the action selection interface, wherein the action selection interface comprises a selectable action. Such a method may further include: receiving an indication of the selection of the selectable action; retrieving an action resource associated with the selectable action; and communicating the action resource to the reproducing apparatus. The action resource may be selected responsive to a profile of a user associated with the reproducing apparatus. The video production may be provided in serval ways including, for example, communicated over a television network, distributed in a tangible medium, or transferred over a computer network. The indication of the action selection interface may take many forms including, for example, a visual highlight. In some illustrative methods, when the reproducing apparatus is coupled to a viewing device, the visual highlight is communicated to the viewing device only if the reproducing apparatus supports the action selection interface. Selectable actions for use with a conforming method include for example, a product purchase action, a promotion participation action, or a information request action. A method for creating a video production including a placement zone and a trigger zone and comprising an image referencing a product and having a selectable action available for communication to a reproducing apparatus according to the invention may include: selecting a placement zone in a video production, the placement zone comprising an image referencing a product; selecting a trigger zone in the video production corresponding to the placement zone; embedding a reference in the trigger zone in said video production to an action selection interface, wherein when reproduced on compatible equipment and communicated to a display, a selectable action in the action selection interface is selectable by a viewer. The video production may include a first track including the trigger zone and a second track including the placement zone, wherein the first and second tracks are synchronized. An apparatus with a processor, a memory, and an input-output system and configured for communication with a reproducing apparatus via a data network may also embody aspects of the invention. Programmed instructions may configure the apparatus to perform a method including receiving a request from a reproducing apparatus, said request corresponding to a trigger from a trigger zone in a video production communicated to the reproducing apparatus; determining whether an action selection interface associated with said request is available; and communicating a characterization of the action selection interface to the reproducing apparatus. A system for providing action selections to an image referencing a product in a video production and operable for use with a reproducing apparatus configured for communication with a display, a data network, and a selection device is another aspect of the invention. The system may include a video production communication device, that can communicate a video production comprising a placement zone and a trigger zone to the reproducing apparatus; and an action resource provider configured for communication with the reproducing apparatus via the data network, the action resource provider receiving a request from the reproducing apparatus corresponding to a trigger in the trigger zone of the video production, the action resource communicating a characterization of an action selection interface to the reproducing apparatus responsive to the request, the action selection interface comprising a selectable action. In such a system, the action resource provider may further receive a request from the reproducing apparatus corresponding to the selectable action; retrieve an action resource associated with the selectable action; and communicate an action resource associated with the selectable action to the reproducing apparatus. Other aspects of our invention provide a method, apparatus, and system for indexical content references in enhanced video productions. A method for indexical content references in accordance with the invention may include: receiving a first request from an integrated enhanced video device (the first request including a first resource identifier and the first resource identifier is extracted from a video production provided to the enhanced video device); also, determining a second resource identifier in response to the first resource identifier; and also, redirecting the first request to the second resource identifier; and thereafter a response is sent to the integrated enhanced video device. In accordance with such a method, determining a second resource identifier may include: identifying at least one parameter; also, identifying at least one parameter value associated with the at least one parameter; and also, determining a second resource identifier that includes the parameter(s) and parameter value(s) in response to the first resource identifier. In accordance with such a method, determining a second resource identifier may include: identifying a parameter of a first type and a parameter of a second type (the parameter of a second type identified in response to a header in the request); and also, identifying a first parameter value associated with the parameter of a first type and a second parameter value associated with the parameter of a second type (the first parameter value is identified in response to an expression associated with the header). In accordance with such a method, redirecting the first request may be either an internal redirection or an external redirection; if external, it may be to a separate server or to the enhanced video device. Another aspect of the invention is a system that may include: a video production communication device; also, an enhanced video device configured to receive a video production from the video production communication device (the video production including, a first resource identifier) and send a request including the resource identifier via a data network; also, a first server communicating via the data network, the first server configured to receive the request, determine a second resource identifier, and redirect the request to the second resource identifier. Such a system may also include a second server, and the second resource identifier may be addressable via the second server. An illustrative apparatus in accordance with the invention and including, at least, a processor, a storage, and an-input output system may be a programmed computer. Programmed instructions may configure the computer to provide special purpose computing machinery including a first request receiver for receiving a first request from a reproducing apparatus, said first request comprising a first resource identifier, said first resource identifier extracted from a video production communicated to said reproducing apparatus; a second resource identifier determiner for determining a second resource identifier responsive to said first resource identifier; and a first request redirector for redirecting said first request to said second resource identifier, wherein thereafter a response is communicated to said reproducing apparatus. The second resource identifier determiner may included, at least, a parameter identifier for identifying a parameter; a parameter value identifier for identifying a parameter value associated with said parameter; and a second resource identifier determiner for determining a second resource identifier comprising said parameter and said parameter value responsive to said first resource identifier. The second resource identifier determiner may include a parameter identifier for identifying a parameter of a first type and a parameter of a second type, wherein said parameter of a first type is identified responsive to a header in said first request; and a parameter value identifier for identifying a first parameter value associated with said parameter of a first type and a second parameter value associated with said parameter of a second type, wherein said first parameter value is identified responsive to an expression associated with said header. The first request redirector may be an internal redirector or an external redirector. If an external redirector, an external redirect message may be sent to the reproducing apparatus. Another aspect of the invention are methods of creating a video production including indexical content references. An illustrative one includes: selecting an indexical reference corresponding to a resource identifier addressable on a data network; determining a reference location in a video production; and encoding said indexical reference at said reference location in said video production, wherein when said video production is reproduced on a compatible reproducing apparatus, said reproducing apparatus communicates a first request to said resource identifier, a server addressable via said resource identifier generates a current content reference, a second request is sent to said current content reference, and responsive to said second request information is communicated to said reproducing apparatus. An additional aspect of versions of the invention provides a system for encoding one or more series of resource identifiers in a video production. An illustrative system includes: an encoding controller; a video production player, operation of the video production player under control of the encoding controller; a resource identifier encoder, the resource identifier encoder configured to receive an input video signal from the video production player, the resource identifier encoder further configured to encode resource identifiers in the input video signal in response to encoding instructions from the encoding controller and provide an output video signal comprising the input video signal and the resource identifiers; and a video production recorder, operation of the video production recorder under control of the encoding controller, the video production recorder receiving the output video signal and storing said output video signal in a storage medium. Yet another aspect of the invention provides a method for encoding one or more series of resource identifiers in a video production. A illustrative method includes: receiving a first starting position for a first series; receiving a first encoding pattern for the first series; embedding a first resource identifier at the first starting position; and embedding the first series of one or more resource identifiers in the video production in accordance with the first starting position. Such a method may further include: receiving a second starting position for a second series; receiving a second encoding pattern for the second series; embedding a second resource identifier at the second starting position; and embedding the second series of one or more resource identifiers in the video production in accordance with the second starting position. Encoding patterns in such methods may be fixed intervals. Resource identifiers in series may be identical.

As used herein, the term "product" includes, at least, goods, services, collective entities, and certifications. DESCRIPTION OF FIGURES While this invention is susceptible of embodiment in many different forms, there are described herein in detail illustrative embodiments with the understanding that the present disclosure is to be considered as an example of the principles of the invention and is not intended to limit the invention to the embodiments illustrated. Fig. 1 shows a block diagram of the system elements 1000 used in conjunction with an illustrative embodiment. In operation, a video production 1100 is provided to a video production communicating device 1800 which communicates the video production 1100 to a reproducing apparatus 1300. The video production 1100 is described in greater detail in connection with Fig. 2 and the reproducing apparatus 1300 is described in greater detail in connection with Fig. 3. The video production 1100 may be in a tangible medium, including, for example, video tape, video disc, or digital video disc (DVD). In some embodiments the video production 1100 is transferred over a computer network. The video production 1100 could be streamed or all, or substantially all, of a file comprising the video production 1100 could be transferred before reproduction begins. The video production communicating device 1800 generates an output operable with the reproducing apparatus 1300 from the video production 1100. For example, if the video production 1100 were by DVD, the video production communicating device 1800 could be a conventional DVD player; if the video production 1100 were transferred over a computer network, the video production communicating device 1800 could be a programmed computer. In some embodiments the video production communicating device 1800 may be a broadcast station, either terrestrial or orbiting. One of skill in the art will recognize which structures, for example the DVD player or programmed computer, are suitable to operate with the video production 1100 depending on its form. In an illustrative embodiment the video production 1100 is communicated to the reproducing apparatus 1300 with a broadcast network and the video production communicating device 1800 is conventional broadcasting hardware. In a more preferred embodiment the broadcast network is a television network; in a still more preferred embodiment, the video production is broadcast as a National Television Standards Committee ("NTSC") video signal; PAL, SEC AM, or high-definition television formats could also be used. Generally, the reproducing apparatus 1300 is capable of receiving the video production communicated by the video production communicating device 1800 and reproducing an video signal comprising the video production to, for example, a display 1200. In addition, generally, the reproducing apparatus 1300 may operate as a client in client-server communications. Also, a selection device 1700 typically operates with the reproducing apparatus 1300 and allows a user (not shown) to select among selectable actions rendered on the display 1200. As one of skill in the art will recognize, the particular form that the selection device 1700 takes may vary with the reproducing apparatus 1300. The reproducing apparatus 1300 communicates over a data network 1400. The data network 1400 may be the same or a separate transmission medium as that though which the video production communicating device 1800 communicates the video production 1100 to the reproducing apparatus 1300, including, for example, a computer network or broadcast. In the illustrative embodiment, the data network is the internet; preferably the hypertext transfer protocol (HTTP) is used. The data network 1400 may, more generally, include other forms of data communication. Configured for communication with the reproducing apparatus 1300 via the data network 1400 is an action resource provider 1500. The action resource provider 1500 provides action resource data to the reproducing apparatus 1300. Action resource data, generally, may include instructions, such as HTML, XML, or SGML pages; scripts, programs, and analogous instructing informational languages which when parsed and rendered on suitable equipment provide for interaction. Typically action resource data includes a characterization of an interface. The interface results from suitable equipment parsing and rendering the characterization. In an illustrative embodiment, the action resource provider 1500 is an HTTP server. However, one skilled in the art will appreciate that the action resource provider 1500 could be other devices capable of communicating action resources with which the reproducing apparatus 1300 is configured to operate. In the illustrative embodiment the action resource provider 1500 communicates with a data storage 1600. The data storage 1600 may store, for example, user profile data, product data, merchant data logs, or program guides. Fig. 2 depicts a representation of a video production 1100. Shown are a first placement zone 1110, a second placement zone 1130, and a Nth placement zone 1150 which correspond, respectively, to a first trigger zone 1120, a second trigger zone 1140, and a Nth trigger zone 1160. The video production 1100 is not limited in the number of placement zones or trigger zones and N may be arbitrarily large or small. The trigger zones need not be precisely coincident with the placement zones. In an illustrative embodiment, a placement zone comprises one or more frames of a video production, the one or more frames comprising an image referencing a product. The number of frames in the placement zone is not limited other than relative to the video production itself. As depicted in Fig. 2, the first placement zone 1110, the second placement zone 1130, and the Nth placement zone 1150 are disjoint. However, this is not fundamental to the invention and, for example, the first placement zone 1110 and the second placement zone 1130 could overlap. In the case of an overlap, plural products could be referenced by the image or images. One skilled in the art will further appreciate that a conventional video production may have one or more placement zones inherent in its layout while, also, placement zones may be added to a conventional video production using well-known editing techniques. Within a trigger zone, for example, the first trigger zone 1120 are one or more triggers. In an illustrative embodiment, triggers are compliant with the CEMA EIA-746 standard or analogous standard. A trigger comprises a resource identifier. In the illustrative embodiment, the resource identifier is a Uniform Resource Identifier (URI) of the form: http://<server name>/<videoprod>/<position> (1) The material denoted within angle-brackets < > are denote names of quantities used in accordance with an illustrative embodiment. In (1) above, <server name> may be any server addressable on the data network 1400, including, for example, the action resource provider 1500, conveniently, the server may be a dedicated server. <videoprod> refers to an identifier of the video production 1100 (or a segment thereof) into which a trigger is embedded. Conveniently, the <videoprod> is not temporally unique, i.e., the video production and embedded trigger may be distributed at arbitrary or multiple times. Triggers may also be indexical as described below in the section titled Indexical Content References. <position> refers to a position within the video production 1100, exemplary positions may be the first trigger zone 1120 or the Nth trigger zone 1160. In the illustrative embodiment, positions may be either temporally indexed or indexed by segments of the video production 1100. More generally, a trigger resource identifier could identify other resources addressable in a client- server data communications network. Conveniently, a trigger may be embedded in the Text-2 service of line 21 of the Vertical Blanking Interval of an analog television signal as specified in CEMA standard EIA- 746 available from The Electronic Industries Association of Arlington, Virginia, U.S.A.. Conventional closed-captioning equipment may be used to embed triggers in accordance with the CEMA standard. One aspect of the invention is the portion of the video production 1100 which is spanned by placement zones or trigger zones. Conventionally, many video productions are viewed primarily for entertainment purposes. It is undesirable for one or more images referencing one or more products to be the dominant images or dominant subject matter in a video production viewed for such purposes. In such a situation, a viewer of the video production may find non-dominant images of insufficient interest to retain viewership, possibly frustrating viewer expectations and forgoing the possibility of selection of selectable actions from an action selection interface made available through the video production. In one embodiment of the invention the placement zones for a given product in a video production according to the invention are less than 50 % of the viewable time of the video production. Alternative embodiments may use, for example, less than 40%, 33%, 25%, 20%, 10%, or 5%. A placement zone may span a single segment in a video production. Shares of the total viewable time of the video production corresponding to one of a number of segments may thus also be used, including, for example (1/6) or about 15%. As one of skill in the art will appreciate having the benefit of this disclosure, a placement zone according to the invention will have some portion of the viewable time of the video production. The video production 1100 operates with the reproducing apparatus 1300 which described in greater detail below with reference to Fig. 3. As noted above, the reproducing apparatus 1300 provides, at least, the functions of receiving and reproducing the video production and of a client in client-server communications. One of skill in the art will recognize numerous structures of programmed or programmable logic also capable of performing these and other functions in accordance with aspects of the invention. Exemplary structures could include, for example, a programmed general purpose computer with suitable video hardware, an integrated receiver/client appliance such as a set-top box, and special purpose computing machinery comprising an application specific integrated circuit (ASIC). Structures currently commercially available which provide at least the above-identified functions include, for example, a WEBTV Plus set-top box available from WebTV Networks, Inc. of Palo Alto, CA, U.S.A. It is contemplated, however, that the present invention will operate with other structures able to perform the above-identified functions (now known or later-developed). The remote control used with the WEBTV Plus set-top box is one example of a suitable form for the selection device 1700. Many others will be recognized by those of skill in the art including, for example, pointing devices used with personal computers, other selection systems such as those based on speech recognition, and touch-screen systems. One of skill in the art will recognize other features incorporated in set-top boxes with which aspects of the invention may operated. Other features may include, for example, a card reader (not shown). The card reader may read identification or financial information cards and the identification or financial information may be used with selectable actions according to the invention. The card reader may work with smart cards, and stored-value cards; in embodiments in which a selectable action includes transfer of value. The card reader may be used to read information from a card for payment of value. Preferably, the reproducing apparatus 1300 communicates with the display 1200 and the data network 1400. In operation, the video production communicating device 1800 communicates the video production 1100 to the reproducing apparatus 1300. A trigger interpreter 1330 interprets triggers in the video production 1100 such as those in the second trigger zone 1140 or the Nth trigger zone 1160. The trigger interpreter 1330 sends a request 1340 via the data network 1400. The request 1340 is received by the action resource provider 1500. The request 1340 may be handled as described in the section below entitled "Indexical Content References". If an action selection interface is available for the particular trigger, an ASI indication 1360 is communicated via the data network 1400 to the reproducing apparatus 1300. An Response inteφreter 1320 parses the ASI indication 1360 and communicates a visual indication of the ASI indication 1360 to a content integrator 1310. The content integrator 1310 integrates the visual portions of the video production 1100 and visuals from the Response inteφreter 1320; the integrated visual may then be communicated to the display 1200. When an ASI characterization 1380 is available for a particular trigger, it is communicated via the data network 1400 to the Response inteφreter 1320 in the reproducing apparatus 1300 as well. The Response inteφreter 1320 parses the ASI characterization 1380 and renders a visual representation thereof which is communicated to the content integrator 1310 for communication to the display 1200. In an illustrative embodiment of the invention the indication of the availability of an ASI is one which is rendered as a visual image on the display 1200. In other embodiments the indication of the availability of an ASI may be audio. In still other embodiments, it may not be communicated to the display 1200. More, generally, the indication of the availability of an ASI may be a portion of the characterization of the ASI itself. In embodiments of the invention where the action resource provider 1500 is an HTTP server using the HTTP protocol, the indication of the availability of an ASI may be, for example, all, or a portion, of an HTTP Response Message sent after the action resource provider 1500 received and inteφreted an HTTP Request Message. The ASI characterization 1380, generally, provides a characterization of an interface which may be parsed and rendered by the reproducing apparatus 1300 to provided one or more selectable actions. Preferably, the ASI characterization 1380 is also communicated using the HTTP protocol and the ASI characterization 1380 is preferably an HTML page which, typically, includes HTML extension tags for use with interactive television. One method of providing selectable actions is to provided links to action resources. However, the selectable actions may be implemented using other conventional client-side or client-server techniques. Action resources may be implemented using well-known programming methods. Conveniently, internet programming methods may be used and an action resource may be implemented with, for example, HTML pages, XML pages; CGI scripts or programs, servlets or other server-side scripts or programs; client-side scripts, applications or applets, or active controls; and other client-server methodologies. One of skill, having the desired functions of the action resource, will apprehend how it could be made or used with conventional programming methods. Fig. 4 depicts a flow diagram of a 'reference embedding' method 4000 in accordance with the illustrative embodiment. From a 'start' terminal 4100 processing continues to a 'video production selection' procedure 4200. The 'video production selection' procedure 4200 entails selecting a video production, such as the video production 1100. Preferably, the video production 1100 already contains one or more images referencing one or more products, however, the additional step of embedding one or more images referencing one or more products may be performed using conventional video editing methods. Next an 'ASI location selection' procedure 4300 is entered in which locations, such as the second placement zone 1130 or the Nth placement zone 1150 are selected as locations in the video production 1100 where action selection interfaces are desired to be provided. Then, an 'ASI reference embedding' procedure 4400 commences in which a reference to an action selection interface is embedded in the video production 1100 at, for example, the second trigger zone 1140 or the Nth trigger zone 1160. In an illustrative embodiment, the reference is a trigger such as that described above. Process flow continues to an 'additional locations' decision procedure 4500. If it desired to select additional locations in the video production 1100 at which action selection interfaces could be made available, the 'additional locations' decision procedure 4500 exits through its 'yes' branch and process flow returns to the 'ASI location selection' procedure 4300 for another iteration. Otherwise, the 'additional locations' decision procedure 4500 exits thorough its 'no' branch and the 'reference embedding' method 4000 completes through an 'end' terminal 4600. Shown in Fig. 5 is a flow diagram of a 'viewer action session' method 5000 in accordance with an illustrative embodiment. Process flow initiates at a 'start' terminal 5100 and continues to a 'video production communication' procedure 5200. The 'video production communication' procedure 5200 involves communication of a video production such as the video production 1100 from the video production communicating device 1800 to the reproducing apparatus 1300. During reproduction of the first trigger zone 1120 when a trigger is encountered the request 1340 is sent and an 'ASI indication communication' procedure 5300 executed by which the ASI indication 1360 is communicated to the reproducing apparatus 1300. Next, an 'ASI characterization communication' procedure 5400 communicates the ASI characterization 1380 to the reproducing apparatus 1300. The ASI characterization 1380 is parsed, rendered, integrated with other visuals, and communicated to the reproducing apparatus 1300. A user (not shown) may then select one or more selectable actions from the action selection interface as displayed on the display 1200. An 'action selection' decision procedure 5500 exits through its 'yes' branch if the user selects one of the selectable action and process flow continues to an 'action resource retrieval' procedure 5600. In the 'action resource retrieval' procedure 5600 an action resource is retrieved from the action resource provider 1500 and communicated to the reproducing apparatus 1300 via the data network 1400 in an 'action resource communication' procedure 5700. The Response inteφreter 1320 parses and renders visuals aspects of the action resource. Next, an 'additional actions' decision procedure 5800 exits through its 'yes' branch if the user selects additional actions and process flow returns to the 'action resource retrieval' procedure 5600. If no action was selected in the 'action selection' decision procedure 5500 or if an additional action is not selected in the 'additional actions' decision procedure 5800 process flow completes through an 'end' terminal 5900. A viewer's perspective of the display 1200 will now be provided to further illustrate aspects of the illustrative embodiment. Shown in Fig. 6A are the display 1200 and an image referencing a product 6100. As noted above, the image referencing a product 6100 may refer either directly or indirectly to the product. Thus, for example, if the image referencing a product 6100 were an image of a car, the referenced product could be the car or, for example, car insurance services, car quality certification, or a car vending collective. Also shown in Fig. 6A is a visual indication of the availability of an ASI 6200. As noted above, the indication of the availability of an ASI may be rendered as a visual image on the display 1200 while in other embodiments the indication of the availability of an ASI may be in other forms. In accordance with the illustrative embodiment the visual indication of the availability of an ASI 6200 could be provided with an HTML page with television extension tags which render the video production 6600 in one portion of the display 1200, and the visual indication of the availability of an ASI 6200 in another. An alternative manner of providing the visual indication of the availability of an ASI 6200 is depicted in Fig. 6B where a visual highlight 6500 of the image referencing a product 6100 is shown. The visual highlight 6500 may be an image edited to highlight the image referencing a product 6100 which may be tracked through multiple frames of the video production 6600. Conveniently the visual highlight 6500 may be implemented with an HTML table. The height and width of the table and its cells are suitably selected for the size of the visual highlight 6500 of the image referencing a product 6100. An image providing the visual highlight 6500 is located in one cell of the table. In some embodiments, the height and width of the cell are adjusted to locate the upper left corner of the visual highlight 6500 image. As the image referencing a product 6100 moves during the video production, the upper left corner of the visual highlight 6500 may be made to track the image referencing a product 6100 by adjusting the height and width of the cell in which the visual highlight 6500 is located. Accordingly, an additional aspect of some embodiments of the invention is a method for tracking an image in a video production with an overlay image. In some embodiments of the invention the action resource provider 1500 detects if the reproducing apparatus 1300 is able to support a type of selectable action in an action selection interface from information in the request 1340 for example, a user- agent header field. In some of these embodiments the visual highlight 6500 is communicated to the reproducing apparatus 1300 only if the reproducing apparatus 1300 supports the selectable action in the action selection interface. Shown in Fig. 6C and Fig. 6D are the display 1200, the image referencing a product 6100 and a rendered characterization of an action selection interface 6300. While the rendered characterization of an action selection interface 6300 is generically depicted, one of ordinary skill in the art will appreciated that it may be as complex as can be parsed and rendered by the reproducing apparatus 1300. As depicted, the rendered characterization of an action selection interface 6300 comprises the plurality of selectable actions 6400 which may be selected by a user with, for example, the selection device 1700. As shown in Fig. 6C the rendered characterization of an action selection interface 6300 appears in a portion of the display 1200 separate from the video production 6600. However, as depicted in Fig. 6D, the rendered characterization of an action selection interface 6300 may appear in the same portion of the display 1200 as the video production 6600. One skilled in the art will quickly appreciate that the views in Fig. 6A, Fig. 6B, Fig. 6C, and Fig. 6D are illustrative and not limiting, rather one of skill will be able to make and use other configurations of the elements in the aforementioned figures. The selectable actions in the plurality of selectable actions 6400 may be any action susceptible to implementation in the action resource provider 1500 and the reproducing apparatus 1300. To further illustrate aspects of the invention, Fig. 7, Fig. 8, and Fig. 9 depict methods for implementing exemplary selectable actions. One of skill in the art will quickly appreciate that these are illustrative and not limiting of the scope of the invention. Rather, one skilled in the art will recognize numerous other selectable actions operable with the invention. One selectable action is a promotion participation action. Conveniently the promotion participation action is a link to action resources which implements the promotion participation action. Further illustrative detail of an may be found in Fig. 7 where a promotion participation action method 7000 is depicted. Functions described in the promotion participation action method 7000 may be implemented with, for example, HTML pages, XML pages; CGI scripts or programs, servlets or other server-side scripts or programs; client-side scripts, applications or applets, or active controls; and other client-server methodologies. Processing initiates at a 'start' terminal 7100 and continues to a 'promotion information communication' procedure 7200 which communicates information about the promotion participation action to the reproducing apparatus 1300. Next, a 'participant information receipt' procedure 7300 stores information communicated by a user of the reproducing apparatus 1300 relevant to participation in the promotion and processing continues to a 'participant registration' procedure 7400. The 'participant registration' procedure 7400 completes the basic information exchange for a promotion participation which may involve data interchange with other servers (not shown), for example those operated by the promoting entity or affiliate. An 'additional participation' decision procedure 7500 allows a participant to select participation in additional aspects of the promotion. Additional participation options may be communicated to the reproducing apparatus 1300 which a user views on the display 1200. If the user does not wish to engage in additional aspects of the promotion, the 'additional participation' decision procedure 7500 exits through its 'no' branch and processing completes through an 'end' terminal 7900. Otherwise, the 'additional participation' decision procedure 7500 exits through its 'yes' branch and a 'next page(s) communication' procedure 7600 communicates one or more pages to the reproducing apparatus 1300 for the participant. A 'next information receipt' procedure 7700 receives additional information as necessary or desired from the participant and processing continues to a 'next participation action' procedure 7800 which performs one or more additional participation actions. These may include, for example, information exchange or storage with a promoting entity or affiliate. It may be desirable for additional participation options to be offered, and processing returns to the 'additional participation' decision procedure 7500 through which such additional participation may begin. Another selectable action is a information request action. Conveniently the information request action is a link to action resources which implements the information request action. Further illustrative detail of an may be found in Fig. 8 where an information request action method 8000 is depicted. Functions described in the information request action method 8000 may be implemented, for example, with HTML pages, XML pages; CGI scripts or programs, servlets or other server-side scripts or programs; client-side scripts, applications or applets, or active controls; and other client-server methodologies. Processing for the information request action method 8000 initiates at a 'start' terminal 8100 and continues to a 'information page(s) communication' procedure 8200 in which one or more pages are communicated to the reproducing apparatus 1300 for communication to the display 1200. Commonly, plural informational options are presented to a user. A 'user input processing' procedure 8300 receives indication of user selections from the reproducing apparatus 1300 and performs any transformations convenient in extracting or reporting aspects of the user selections. In addition, the 'user input processing' procedure 8300 may also log, for example, user data or information request data. Then an 'information generation' procedure 8400 generates information output for reporting to the user. The 'information generation' procedure 8400 may employ any of many known report generation or extraction methods to produce the requested information for presentation to the user. An 'information communication' procedure 8500 then communicates requested information to the user. The requested information may be communicated to the user via the reproducing apparatus 1300 and the display 1200 or be communicated through other methods including, for example, by post or facsimile. The information request action method 8000 completes through an 'end' terminal 8600. Another selectable action is a product purchase action. Conveniently the product purchase action is a link to action resources which implements the product purchase action. Further illustrative detail of an may be found in Fig. 9 where a product purchase action method 9000 is depicted. Functions described in the product purchase action method 9000 may be implemented, for example, with HTML pages, XML pages; CGI scripts or programs, servlets or other server-side scripts or programs; client-side scripts, applications or applets, or active controls; and other client-server methodologies. One of skill having the benefit of this disclosure will appreciate that many known and commercially available electronic commerce systems may be used to perform aspects of the product purchase action method 9000. Processing in the product purchase action method 9000 initiates at a 'start' terminal 9100 and continues to a 'transaction page(s) communication' procedure 9200 in which pages used to present the product purchase transaction are communicated to the reproducing apparatus 1300 for rendering on the display 1200. Upon user input of transaction information a 'secure transaction verification' procedure 9300 verifies transaction information with a transaction security verification mechanism. One of skill in the art will recognize many transaction security verification mechanisms. Conveniently, a predetermined identification number personal to the user may be used. Next, a 'merchant communication' procedure 9400 communicates transaction information from the user and product information to a merchant. The merchant may or may not have received sufficient information to complete the transaction depending on the particular requirements of the merchant or transaction. A 'complete transaction' decision procedure 9500 exits through it s 'yes' branch if the 'merchant communication' procedure 9400 returns an indication that the transaction was completed. This is communicated to the user and processing completes through an 'end' terminal 9995. If the transaction could not be completed, the 'complete transaction' decision procedure 9500 exits through its 'no' branch and an 'incomplete transaction' output block 9600 reports to the user that the transaction could not be completed at the current time on the basis of the information thus far received. A 'complete now' decision procedure 9700 prompts the user if they wish to complete the transaction now. If so, the 'complete now' decision procedure 9700 exits through its 'yes' branch and a transaction completion' procedure 9800 completes the rest of the transaction. Processing then completes through the 'end' terminal 9995. If the user does not wish to complete the transaction at the current time, the 'complete now' decision procedure 9700 exits through its 'no' branch and a 'state information storage' procedure 9900 stores information about the current state of the transaction for later completion by the user. Processing completes though the 'end' terminal 9995. Methods according to the invention may be computer implemented either in whole or in part. Fig. 10 depicts a computer system 10000 capable of embodying aspects of the invention. The action resource provider 1500 may be structures in accordance with the computer system 10000. The computer system 10000 comprises a microprocessor 10010, a memory 10020 and an input/output system 10030. The memory 10020 is capable of being configured to provide a data structure 10040 which may contain data manipulated by the computer system 10000 when embodying aspects of the invention. Further illustrated is a media drive 10070, such as a disk drive, CD-ROM drive, or the like. The media drive 10070 may operate with a computer-usable storage medium 10075 capable of storing computer- readable program code able to configure the computer system 10000 to embody aspects of the invention. The input/output system 10030 may also operate with a keyboard 10050, a display 10060, a pointing device 10090, a data storage 10045 ,or a network such as the data network 1400. As illustrated, the computer system 10000 is general-puφose computing machinery. As one of skill recognizes programmed instructions may configure general puφose computing machinery to embody structures capable of performing functions in accordance with aspects of the invention. Special puφose computing machinery including, for example, an application specific integrated circuit (ASIC) may also be used. One skilled in the art will recognize numerous structures of programmed or programmable logic capable of being configured to embody aspects of the invention. In some embodiments, the computer system 10000 is a SPARC-based workstation from Sun Microsystems of Mountain View, CA, running the SOLARIS operating system and the Apache HTTP server with a Secure Sockets Layer module. In illustrative embodiments of the invention, computer program code configures a computer to embody aspects of the invention. So configured, representations of physical quantities and characteristics are manipulated through a series of operations to achieve aspects of a method, apparatus, and system for providing action selections to an image referencing a product in a video production. One skilled in the art will appreciate the distinction between the manipulation of physical quantities and representations thereof within a computer and will quickly apprehend when reference is being made to one or the other. In some illustrative embodiments, the action resource provider 1500 is a computer system similar to the computer system 10000 and runs an HTTP server. However, one skilled in the art will appreciate that the action resource provider 1500 could be other devices with which the reproducing apparatus 1300 is configured to operate. In the illustrative embodiment the action resource provider 1500 communicates with a data storage 1600. The data storage 1600 may store, for example, user profile data, product data, merchant data logs, or program guides User profile data may contain information useful to customizing content and following through on information request, promotion participation, product purchase actions, and other selectable actions. This includes both information explicitly supplied by the user or taken from service registration data, and information derived from the user's pattern of usage. In an illustrative embodiment, explicit data includes name, address, phone number, birthdate, preferred payment methods, billing address, income, and sex. Usage data may include shows watched, the frequency of performing the different interactive actions, show loyalties, and Web sites visited. A preferred mode of using the user profile data to customize content will conveniently involve first deriving intermediate data. For example, it is simpler to derive an age, or an age group, rather than directly customizing from birthdate. Thus the user profile may include the results of calculations and aggregations of data values to create a smaller and therefore more manageable space of content variations. INDEXICAL CONTENT REFERENCES An additional aspect of the invention involves a video production comprising indexical content references. Indexical content references may be beneficially used in conjunction with the zoned system described above, however they are not limited to this use. Fig. 11 depicts a flow diagram of a method for creating a video production including indexical content references 11000 in accordance with an illustrative embodiment. A video production including an indexical content reference, when reproduced on compatible equipment such as the reproducing apparatus 1300 (described above) engages the equipment initiate a request to a resource identifier included in the indexical content reference wherein a server addressable via a data network generates a current content reference. Another request is sent to the current content reference and responsive thereto, a response is communicated to the compatible equipment, e.g., the reproducing apparatus 1300. Process flow initiates at a 'start' terminal 11100 and continues to an 'indexical reference selection' procedure 11200. The 'indexical reference selection' procedure 11200 comprises selection of an indexical reference to be encoded in the video production. Selection may be by a human operator or may be automated. Next, processing continues to a 'reference location determination' procedure 11300 that comprises determining the location within the video production where the indexical reference selected by the 'indexical reference selection' procedure 11200 can be encoded. The 'reference location determination' procedure 11300 may also be performed by a human operator or may be automated. One of skill in the art will recognize many schemes for determining the location within the video production where the indexical reference may be encoded including, for example, time or position-based schemes, and content-based schemes. Additionally, a zone-based scheme may be used, as described above. Process flow continues to an 'indexical reference encoding' procedure 11400 that comprises encoding the indexical reference selected by the 'indexical reference selection' procedure 11200 at the location in the video production determined by the 'reference location determination' procedure 11300. The video production may be in many conventional forms and conventional video editing equipment known to those skilled in the art may be used to encode the indexical reference. Conveniently, the indexical reference may be encoded in the vertical blanking interval ("VBI") of a conventional analog television broadcast using conventional closed-captioning systems. The Text-2 service of line 21 of the VBI may be used in accordance with CEMA standard EIA- 1746 (available from the Electronic Industries Association ("EIA") of Arlington, VA, U.S.A.). When the video production is in other forms including, for example, digital broadcast or narrowcast video, HDTV, encoded on a tangible medium, or a file for use with a video application, encoding schemes suitable to the form should be used and one of skill in the art will recognize how to encode an indexical reference in accordance with the invention in many conventional forms of distributing the video production. Process flow completes through an 'end' terminal 11500. A video production created according to the method for creating a video production including indexical content references 11000 may be used with other aspects of the invention including, for example, those depicted in Fig. 1. Fig. 12 depicts a block diagram of the elements in an operating environment of a system 12000 in accordance with an illustrative embodiment. Corresponding components in Fig. 12 are similar to those described above in connection with Fig. 1 and reference should be made to the portion of the description above In Fig. 12, able to communicate with the reproducing apparatus 1300 via the data network 1400 is a first server 12500 and a second server 12800, which may communicate, respectively, with a first data storage 12600 and a second data storage 12900. Generally there need not be functional differences between the first server 12500 and the second server 12800 and accordingly subsequent discussion will be made with reference to the first server 12500 except where additional clarity may be had by reference to the second server 12800. Further, as one of skill will appreciate, not ail embodiments require more than one server, and other embodiments may operate with more than two servers. Additional description of illustrative structures that may implement functions of the first server 12500 is provided in connection with Fig. 10 above. In an illustrative embodiment, the first server 12500 is an HTTP server. However, one skilled in the art will appreciate that the first server 12500 could be other devices with which the reproducing apparatus 1300 is configured to operate. In illustrative embodiments the first server 12500 communicates with a first data storage 12600. The first data storage 12600 may store, for example, user profile data, product data, merchant data logs, or program guides, data objects comprising parameters or parameter values, and data objects comprising data operable with programmed instructions for mapping a first request to a second request. Referring to Fig. 3, n operational mode, the video production communicating device 12100 communicates the video production to the reproducing apparatus 1300. A trigger inteφreter 1330 inteφrets triggers in the video production and extracts a resource identifier. The trigger inteφreter 1330 sends a request 1340 comprising the resource identifier via the data network 12400. A server 12380 receives the request 1340. The server 12380 may be the first server 12500, the second server 12800, or another device addressable via the data network 12400. The reproducing apparatus 1300 receives a response 1360 via the data network 12400 and a response inteφreter 1320 parses and renders the response 1360. Rendered visual aspects of the response 1360 are sent to a content integrator 1310 which integrates visual aspects of the response 1360 with visual aspects of the video production for communication to the display 12200. Fig. 13 depicts an 'indexical trigger' method 15000 in accordance with an illustrative embodiment. Process flow according to the 'indexical trigger' method 15000 preferably occurs according to programmed instructions executing on networked computing machinery, for example, the first server 12500. The 'indexical trigger' method 15000 may be implemented with one or more server-side scripts or programs including, for example, JAVA servlets or CGI scripts or programs. Process flow initiates at a 'start' terminal 15050 and continues to an 'indexical reference request' input block 15100. The 'indexical reference request' input block 15100 comprises a request to an addressable network resource such as the request 1340. The request may be compliant with the HTTP protocol in its various versions including, for example, 1.0, draft 1.1, and draft HTTP-NG. It is contemplated that the present invention could also operate with later-developed versions of the HTTP protocol or its successors. Typically, the request contains, at least, a resource identifier, one or more header field-value pairs which may specify, for example, functional parameters to be used in a client- server session initiated by the request, and a terminator. The resource identifier in the request of the 'indexical reference request' input block 15100 is typically extracted from a trigger. When the request is HTTP compliant, the resource identifier commonly is an uniform resource identifier ("URI") and the one or more header field- value pairs are as specified in the HTTP protocol standard(s). In some illustrative embodiments, triggers are compliant with CEMA standard EIA- 1746 available from The Electronic Industries Association of Arlington Virginia, U.S.A. In these embodiments, the resource identifier in the trigger is an uniform resource identifier and the uniform resource identifier in the trigger is of the form: http ://<server name>/<vid eoprod>/<position> ( 1 ) The material denoted with angle-brackets <> are quantities used in accordance with the illustrative embodiment. In (1) above, <server name> may be any server addressable on the data network 1400, including, for example, the first server 12500, conveniently, the server may be a dedicated server; <videoprod> refers to an identifier of the video production or a segment thereof into which the trigger is embedded; <position> refers to a position within the video production. Thus, one particular uniform resource identifier according to (1) could be: http://t.b3tv.com/video7/05 (la) One of skill in the art having the benefit of this disclosure will appreciate that the present invention is not limited to triggers comprising uniform resource identifiers, and trigger uniform resource identifiers are not limited to the form illustrated in (1) above. One aspect of the present invention is that the resource identifier in the trigger is what is termed herein "indexical". "Indexical" triggers may refer to triggers that comprise a resource identifier including a path to be used by a server in locating an associated resource that is independent (or substantially independent) of the content addressable by the resource identifier. One of skill in the art will appreciate that indexical triggers comprise resource identifiers that are distinct from the conventional resource identifier used, for example, in connection with World Wide Web sites, where a path specified to be used by a server in locating an associated resource is dependent (or substantially dependent) on the content of resource addressable by the resource identifier. Indeed, is common practice in connection with World Wide Web sites to specify an uniform resource identifier with a path that precisely specifies a path in a file system where content (for example an HTML page or image) is stored. One manner in which indexical resource identifiers may be made independent (or substantially independent) from the content addressable by the resource identifier is for the path of the resource identifier to indicate the medium in which the resource identifier is embedded, for example, the path may indicate that the resource identifier is embedded in a video broadcast. Yet another manner in which indexical resource identifiers may be made independent (or substantially independent) from the content addressable by the resource identifier is for the path of the resource identifier to indicate the broadcast context in which the resource identifier is embedded. For example, the path may indicate a name of a video production and a position in the video production. One, non-limiting, example of the use indexical trigger resource identifiers is for the <videoprod> to be an identifier of the video production in which the resource identifier is embedded and <position> to refer to an indexed position within the video production. Other examples included, one or more strings which provide only video production information or both video production and position information. Such one or more strings may themselves be easily recognizable as conveying their included information or may be the product of a hash function, transform, and/or other modification which requires data processing to render their information easily recognizable. An additional example of an indexical reference could be as a key for use with a data structure storing key-value pairs on a server. One skilled in the art having the benefit of the teachings herein will quickly appreciate many modifications, variations, and adaptations of indexical triggers as herein described which, while departing from the illustrative examples, remain within the spirit and scope of the present invention as set forth in the appended claims. An indexical trigger allows enhancing content customization through use of parameterized resource identifiers without consuming limited bandwidth in a video production by providing a generally compact resource identifier which is mapped to a parameterized resource identifier by a sever, such as the first server 12500. The server may then redirect the parameterized resource identifier and a response can be communicated to the reproducing apparatus which uses the paramterized resource as a BASE element for further interaction. Further, an indexical trigger allows for time-appropriate enhancing content to be provided in connection with enhanced video production. A resource identifier in the indexical trigger need not address particular enhancing resources. A server such as the first server 12500, may contain easily-updatable data comprising time-appropriate enhancing resources. The server may redirect the resource identifier from the indexical trigger to one or more pages providing time-appropriate enhancing resources. Further, an indexical resource identifier allows for opporuntistic provision of enhancing content. An indexical trigger comprising a resource identifier dedicated to opportunistic enhancing content may be embedded in a video production. When it is determined to provide opportunistic enhancing content, it may be done at the server. Still further, indexical triggers may be used to facilitate internationalization of enhancing content. The resource identifier in the trigger, itself, may be neutral with respect to national or linguistic group. However, a server, the first server 12500 may gain information from header fields and associate expressions in the request about language or location information associated with a viewer or the reproducing apparatus. These may be used by the server to determine an appropriate language in which to respond. A network identifier associated with the reproducing apparatus, e.g. an IP address, may also be used to identify the country of origin of the requesting hardware and this too, may be used for suitable internationalization with indexical triggers. Processing of the 'indexical trigger' method 15000 continues to an 'trigger URI parameter extraction' procedure 15150. The 'trigger URI parameter extraction' procedure 15150 examines the uniform resource identifier in the request 1340 for the values associated with the <videoprod> or <videoprod> and <position> quantities and extracts this information. Next, a 'trigger URI properties retrieval' procedure 15200 retrieves a first data object comprising first key-value pairs stored in data storage accessible by the server implementing the 'indexical trigger' method 15000. Using the quantities extracted from the <videoprod> or <videoprod> and <position> portions of the uniform resource identifier as a key, a 'project lookup' procedure 15250 looks for a value in the first data object associated with the key- herein termed a "project"— and a 'project properties retrieval' procedure 15300 retrieves and stores a second data object comprising second key- value pairs stored in data storage accessible by the server implementing the 'indexical trigger' method 15000. Next, a 'parameter lookup' procedure 15350 uses a string associated with the parameters as a key with the second key-value pairs to lookup parameters associated with the project. A 'parameter storage' procedure 15400 stores a first parameter in a data structure. Conveniently, the data structure facilitates sorted retrieval, for example, a binary search tree. A 'remaining parameters' decision procedure 15450 exits through its "yes" branch if additional parameters remain and process flow returns to the 'parameter lookup' procedure 15350 for another iteration of parameter lookup and storage. When no more parameters remain, the 'remaining parameters' decision procedure 15450 exits through its 'no' branch and processing continues to a 'second URI generation' procedure 15500. The 'second URI generation' procedure 15500 will be described in greater detail with reference to Fig. 14 below. Briefly, here, the 'second URI generation' procedure 15500 generates an uniform resource identifier comprising parameter-parameter value pairs. Processing continues to a 'request redirection' procedure 15600 that receives the uniform resource identifier generated by the 'second URI generation' procedure 15500 and redirects the request received in the 'indexical reference request' input block 15100 to the second uniform resource identifier generated by the 'second URI generation' procedure 15500. In some embodiments of the invention the redirection is internal, that is, the redirected request is communicated directly to the server performing the 'indexical trigger' method 15000. In other embodiments, the redirection is external. Some embodiments employing external redirection communicate a redirect message to the reproducing apparatus 1300 comprising the uniform resource identifier generated by the 'second URI generation' procedure 15500. Typically in these embodiments the reproducing apparatus 1300 then sends a redirected request to the second uniform resource identifier. Other embodiments employing external redirection communicate the redirect message to a separate server. Such an embodiment can be further illustrated with reference to Fig. 12. Initially, the reproducing apparatus 1300 communicates the request received in the 'indexical reference request' input block 15100 via the data network 1400 to, for example, the first server 12500. Then, the first server 12500 performs steps of the 'indexical trigger' method 15000 and communicates the redirect message to the second server 12800 via the data network 1400. The second server 12800 may then perform additional processing responsive to the redirect message including, for example, steps of the 'indexical trigger' method 15000. Whether external, internal, or other type of redirection is used in the 'request redirection' procedure 15600, processing continues to a 'response' output block 15700 that comprises a response sent to the reproducing apparatus 1300. The response may be, for example, an HTTP-compliant response message, although other data transfer protocols may be also be used. Processing completes through an 'end' terminal 15800. Further detail of the 'second URI generation' procedure 15500 will now be provided with reference to Fig. 14. Process flow initiates at a 'start' terminal 15505 and continues to a 'protocol and initial path addition' procedure 15510. As noted above, in accordance with an illustrative embodiment, the resource identifier generated by the 'second URI generation' procedure 15500 is an uniform resource identifier. As one of skill in the art recognizes, uniform resource identifiers conventionally begin with a designation of a protocol or scheme to use in attempting retrieval of the identified resource which is followed by one or more elements of a path; accordingly, the 'protocol and initial path addition' procedure 15510 begins formation of the uniform resource identifier by adding these elements. Process flow continues to a 'remaining parameters' decision procedure 15520 which determines if parameters remain for addition to the uniform resource identifier and thus controls exit from an iterative block comprising elements described below. Typically during a first iteration of the 'remaining parameters' decision procedure 15520 exits through its 'yes' branch and process flow continues to a 'parameter retrieval' procedure 15530 that retrieves a parameter from the data structure used with the 'parameter storage' procedure 15400. Next, a 'parameter value' decision procedure 15540 determines if a parameter value associated with that parameter is available. If so, the 'parameter value' decision procedure 15540 exits through its 'yes' branch and a 'parameter value assignment' procedure 15560 assigns a variable the parameter value; if not, the 'parameter value' decision procedure 15540 exits through its 'no' branch and an 'empty string assignment' procedure 15550 assigns the variable the value of the empty string. Next, a 'pair concatenation' procedure 15570 concatenates the parameter-parameter value pair to the uniform resource identifier. In this step, the parameter and parameter value are separated by an equals sign ("="). Additionally, the 'parameter value assignment' procedure 15560 concatenates a "/" to divide parameter-parameter value pairs. Process flow returns to the 'remaining parameters' decision procedure 15520 to begin another iteration. When sufficient iterations have occurred to retrieve all parameters, the 'remaining parameters' decision procedure 15520 exits through its 'no' branch and process flow continues to an 'initial resource concatenation' procedure 15580. Frequently it is desirable for an initial resource comprising references to other resources to be first presented to a user. The 'initial resource concatenation' procedure 15580 facilitates this by concatenating a designator of the initial resource to the path. Process flow completes through an 'end' terminal 15590 To further aid in understanding the 'second URI generation' procedure 15500, a non- limiting illustration of an uniform resource identifier which could be created in accordance with an illustrative embodiment of the invention is shown by (2) below. http://<server name>/p/<project>/<name 1 >=<value 1 >/<name2>=<value2>/<name3>=/start.html (2) As shown in (2) quantities exemplifying particular aspects of the content URI are shown with angle-brackets <>. In (2), "http://<server name>/p/<project>" illustrates subject matter that could be added by the 'protocol and initial path addition' procedure 15510. Parameters are illustrated by <namel>, <name2>, and <name3>; parameter values are illustrated by <valuel>, <value2>, and an empty string following the equals sign which follows <name3>. An initial resource designator is illustrated by "start.html" as could be added by the 'initial resource concatenation' procedure 15580. As one skilled in the art having the benefit of this disclosure will appreciate, the present invention is not limited to URIs of the length, arrangement, or form (abstractly or concretely) of the exemplary content URI in (2); nor is the present invention limited to URIs generally, rather (2) illustrates an example of a resource identifier in the form of a URI which could be created by one embodiment among many possible embodiments of the invention which lie within the spirit and scope of the invention as set forth in the appended claims. Parameters and parameter values may be obtained from header fields and associated expressions in the request received in the 'indexical reference request' input block 15100. Exemplary header fields used with versions of the HTTP protocol are shown in table 1 below: In preferred embodiments of the invention, use of header fields and header field values is in compliance with the HTTP protocol available from the World Wide Web Consortium (W3C), Massachusetts Institute of Technology, Laboratory for Computer Science, Cambridge, Massachusetts, U.S.A. Parameters may also include information obtained from an network address associated with the reproducing apparatus 1300 including, for example, an IP address. In certain circumstances it could be possible to use this information to determine an approximate geographic location for the reproducing apparatus 1300 which may be correlated to time zones or other geographic information. Geographic or Date field information could be used infer a time zone for the reproducing apparatus 1300 initiating the request. Time zone information could then be used in conjunction with an Electronic Program Guide ("EPG") to gather additional information regarding the video production being viewed by a viewer. Some embodiments of the invention may use parameters based on an EPG alone for creating a response responsive to the broadcast context in which a request was initiated. Conveniently, parameter-parameter value pairs are added to the content URI by the 'second URI generation' procedure 15500 in alphanumeric order by use of a data structure in the 'parameter storage' procedure 15400 which, when traversed, yields entries in such an order. In an illustrative embodiment parameters are added to the content URI with empty string parameter values when no parameter values are available. Alternative, embodiments omit parameter-parameter value pairs for which no parameter value is available. Still further, in some embodiments the second resource identifier has neither parameters nor parameter values, while in still other embodiments, the second uniform resource identifier is of other forms including those known in the art. Parameters relating to a particular viewer or household using the reproducing apparatus 1300 to initiate the request could also be used including, for example, age, gender, other demographic or psychographic parameters. Additionally, parameters relating to financial information including, for example, known payment instruments for a viewer may also be used. Parameters relating to financial information may be conveniently used in conjunction with applications of the invention to electronic commerce. In addition, parameters and parameter values may be carried across links by functionality analogous to using the second URI as an absolute URI that acts as a BASE element for resolving relative URIs in accordance with the HTML specification (available World Wide Web Consortium (W3C), Massachusetts Institute of Technology, Laboratory for Computer Science, Cambridge, Massachusetts, U.S.A.). ENCODING Another aspect of the present invention involves a method and system for encoding one or more series of resource identifiers in a video production. Fig. 15 depicts 'series encoding' system 17000 for encoding one or more series of resource identifiers in a video production. The 'series encoding' system 17000 includes an encoding controller 17100. The encoding controller 17100 controls aspects of the operation of a video production player 17200, a resource identifier encoder 17300, and a video production recorder 17400. The encoding controller 17100 may be a programmed general puφose computer or may be special-puφose computing hardware. The video production player 17200 communicates a video signal to the resource identifier encoder 17300 under the control of the encoding controller 17100. In some embodiments the video production player 17200 could be a conventional video cassette player, in other embodiments, the video production player 17200 could be a random access video player, such as a DVD player, or a computer programmed to play a video file. The resource identifier encoder 17300 receives the video signal from the video production player 17200 as an input video signal. The resource identifier encoder 17300 receives instructions from the encoding controller 17100 for embedding resource identifiers in the input video signal. The resource identifier encoder 17300 may be conventional closed- captioning equipment. In some embodiments the resource identifiers could be embedded in the VBI of a NTSC video signal; in others they could be embedded in a synchronized companion track to the video production. The resource identifier may be portions of triggers according to CEMA standard EIA-1746 or analogous standard. The resource identifier encoder 17300 generates an output video signal that comprises the input video signal and resource identifiers embedded therein according to instructions received from the encoding controller 17100. The output video signal is communicated to a video production recorder 17400 where it is stored on a video production storage medium 17500. The video production recorder 17400 may be, for example, a conventional video cassette recorder, DVD recorder, other device capable of recording a video signal, or device capable of storing a video file. The video production storage medium 17500 is suitably chosen for operation with the video production recorder 17400. In operation, the 'series encoding' system 17000 may work as follows. A user inputs information to the encoding controller 17100 regarding a series of resource identifiers for encoding in a video production. Next, the encoding controller 17100 determines responsive to the user input positions in the video production at which the resource identifiers should be embedded and appropriate resource identifiers for encoding at those positions. The encoding controller 17100 sends a signal to the video production player 17200, the resource identifier encoder 17300, and the video production recorder 17400 to initiate encoding. The video production player 17200 provides a video signal to the resource identifier encoder 17300. The encoding controller 17100 is able to determine the position in the video production which is being sent from the video production player 17200 to the resource identifier encoder 17300 at any given moment. The mechanism for achieving this function may vary with the particular video production player 17200. In some embodiments, the encoding controller 17100 could be provided with the rate of playback the video production player 17200 and the encoding controller 17100 could track playback based on time. In other embodiments, the video production player 17200 could provide an output signal to the encoding controller 17100 which could be used for tracking. In still other embodiments, the video production player 17200 could provide random access and the encoding controller 17100 could provide the access position. When the encoding controller 17100 determines that an appropriate position in the video production has been reached, the encoding controller 17100 sends a signal and the appropriate resource identifier to the resource identifier encoder 17300. The resource identifier encoder 17300 embeds the resource identifier in the input video signal received from the video production player 1 200. An output is generated by the resource identifier encoder 17300 that comprises the input video signal and the embedded resource identifiers which is recorded on a video production storage medium 17500 by the video production recorder 17400. In an illustrative embodiment the video production storage medium 17500 is a video cassette and the video production played by the video production player 17200 may also be a videocassette. In this embodiment it can be seen that operation of the 'series encoding' system 17000 takes a raw video production played by the video production player 17200 and gives to the raw video production new qualities, properties, and combinations of information. Examples of new properties may include, for example, resource identifiers encoded on the video cassette in one or more particular patterns. Examples of new qualities may include, for example, that when the video cassette is communicated to compatible equipment, the compatible, the resource identifiers configure the compatible equipment to communicate a particular request message to a data network for receipt by, for example, a server. For example, the resource identifier may be seen as instructions that configure a client computing system to perform a particular task, e.g., sending a particular request to a network. In other embodiments the video production storage medium 17500 could be other media suitable for storing a video production. The 'series encoding' system 17000 is illustrative of structural elements that may perform steps of a method for encoding one or more series of resource identifiers in a video production. Fig. 16 depicts a flow diagram of a 'series encoding' method 18000 for encoding one or more series of resource identifiers in a video production in accordance with an illustrative embodiment. For puφoses of illustration, reference will be made to elements of the 'series encoding' system 17000 with the understanding that in other embodiments, other suitable structures may perform steps of the 'series encoding' method 18000. Process flow initiates at a 'start' terminal 18100 and continues to a 'video production name input' procedure 18200. The 'video production name input' procedure 18200 provides a query for a name of a video production for encoding. Queries made in the illustrative embodiment of the 'series encoding' method 18000 may be made, for example, to a user or a database. The 'video production name input' procedure 18200 then receives and stores the name. Process flow continues to an 'encoding series start input' procedure 18300 that provides a query for a first starting position for a first series. The first starting position is conveniently input as a time input, for example, 5 minutes from the start of the video production, although a displacement measure or other suitable position identifier could be used in other embodiments. Process flow continues to an 'encoding series pattern input' procedure 18400. The 'encoding series pattern input' procedure 18400 provides a query for a first encoding pattern for the first series of resource identifiers. In some embodiments, the first encoding pattern may be a fixed interval so that elements of the first series could be placed in the video production at fixed intervals. In other embodiments a more complex pattern could be used; in some embodiments, a list of entries could be input and would thus provide the first encoding pattern. Next, an 'encoding series storage' procedure 18500 computes the positions in the video production at which each of the first series of resource identifiers should be embedded and the appropriate resource identifiers for embedding at the positions. As noted, in some embodiments, each of the resource identifiers could be the same. In other embodiments, a portion of the resource identifiers could include a <position> portion relating to the position of the resource identifier in the video production. In still other embodiments a portion of the resource identifier could be a counting index. Many other schemes will be appreciated by one of skill in the art having the benefit of this disclosure within the spirit and scope of the invention as set forth in the appended claims. The 'encoding series storage' procedure 18500 then stores the positions in the video production at which each of the first series of resource identifiers should be embedded and the appropriate resource identifiers for embedding at the positions. Next, a 'remaining series' decision procedure 18600 determines whether additional encoding series are desired for addition to the video production. In an illustrative embodiment the 'remaining series' decision procedure 18600 makes this determination by querying a user. If an additional encoding series is desired, the 'remaining series' decision procedure 18600 exits through its 'yes' branch and process flow return to the 'encoding series start input' procedure 18300 to receive a next starting position and a next encoding pattern. When plural encoding series are desired, the 'encoding series storage' procedure 18500 maintains an updated list of elements of the plural encoding series in order that all resource identifiers of the plural encoding series may be embedded in the video production during a single pass through the video production. When no additional encoding series are desired, the 'remaining series' decision procedure 18600 exits through its 'no' branch and process flow continues to an 'encoding initiation' procedure 18700. The 'encoding initiation' procedure 18700 initiates the process of embedding the resource identifiers from the one or more encoding series in the video production. The 'encoding initiation' procedure 18700 sends a signal to the video production player 17200, the resource identifier encoder 17300, and the video production recorder 17400 that begins the encoding process under the control of the encoding controller 17100 that typically performs the 'encoding initiation' procedure 18700. Process flow enters a 'resource identifier encoding' procedure 18800 that detects when a position in the video production is reached where a resource identifier should be embedded. The 'resource identifier encoding' procedure 18800 then provides a signal to the resource identifier encoder 17300 that a resource identifier should be embedded along with the resource identifier. The resource identifier encoder 17300 embeds the resource identifier. An 'encoding complete' decision procedure 18900 determines when all resource identifiers have been embedded. The 'encoding complete' decision procedure 18900 exits though its 'no' branch and loops back to the 'resource identifier encoding' procedure 18800 while resource identifiers remain to be embedded. When no resource identifiers remain to be embedded, the 'encoding complete' decision procedure 18900 exits through its 'yes' branch and process flow completes through an 'end' terminal 18950. It will be appreciated that the 'series encoding' method 18000 could be used to encode both simple and complex patterns of resource identifier in a video production. It may be desirable for identical resource identifiers to be embedded at periodic intervals in a video production; in this way it can be assured that if a viewer joins a video production after the beginning of the video production, they will be presented with the opportunity to retrieve resources available via the resource identifier. It may further be desirable to provide resource identifiers every Tl minutes starting with the SI 'th minute, for some arbitrary positive Tl and SI , e.g. every five minutes starting with the second minute of the video production. The 'series encoding' method 18000 may be used to provide such an arrangement by providing the Sl 'th minute in the 'encoding series start input' procedure 18300 and a fixed interval of Tl minutes in the 'encoding series pattern input' procedure 18400. Similarly it may be desirable for a first series and a second series of resource identifiers to be provided, starting with the Sl 'th and S2'th minutes, respectively, and continuing every Tl and T2 minutes, respectively. The 'series encoding' method 18000 may be used to provide such an arrangement by providing the S 1 'th minute and the Tl 'th interval in a first iteration of the 'encoding series start input' procedure 18300 and the 'encoding series pattern input' procedure 18400 and providing the S2'th minute and the T2'th interval in a second iteration of the 'encoding series start input' procedure 18300 and the 'encoding series pattern input' procedure 18400. One of skill in the art, having the benefit of this disclosure, will appreciate that arbitrarily complex or numerous encoding patterns may be provided in conjunction with the 'series encoding' method 18000. Although the present invention has been described in terms of illustrative embodiments, one skilled in the art will understand that various modifications and alterations may be made without departing from the scope of the invention. Accordingly, the scope of the invention is not to be limited to the particular embodiments discussed herein, but should be defined only by the appended claims and equivalents thereof. All patents, patent applications, documents, standards, protocols, and draft protocols referred to herein are incoφorated herein by this reference in their entirety.
