Abstract:
According to one embodiment of the invention, a method of registering, and perhaps substituting broadcast television advertisements for lesser, time intensive advertisements is described. The method comprises (i) receiving digital content including segments of a audiovisual program separated by at least one broadcast advertisement; (ii) detecting an operation that alters playback of the broadcast advertisement; (iii) in response to detecting the alters playback, retrieving a stored advertisement from a local memory storage unit, the stored advertisement being associated with a genre of advertisements selected by a user; and (iv) outputting for display the stored advertisement in lieu of the broadcast advertisement, the stored advertisement having a playback time less than a prescribed amount of a normal playback time of the broadcast advertisement. Other embodiments are described and claimed.

Description:
FIELD 
       [0001]    The invention is related to the field of content recordation. More specifically, certain embodiments of the invention are directed to a registration scheme for the selection and substitution of lesser, time intensive advertisements within incoming television signals for playback. 
       BACKGROUND 
       [0002]    Currently, television is widely used as a source of both information and entertainment. Cable and satellite systems broadcast tens or even hundreds of channels of programming. Given the large number of programs that are available to a viewer and are broadcast at prescribed times, in some situations, a viewer may be unable to watch all of the programs that he or she wishes to see. Consequently, over the last few decades, a number of electronic devices have been developed to record broadcast television signals. 
         [0003]    For instance, video cassette recorders (VCRs) provide viewers with an ability to record incoming audiovisual programs on a magnetic tape and to subsequently view such programs. A timer in the VCR allows the user to record these audiovisual programs at their prescribed broadcasting time. Consequently, the recorded programs are available for playback at the user&#39;s convenience. 
         [0004]    Thereafter, the basic concept of VCRs has been extended to a hard-drive or semiconductor based recording devices that is commonly referred to as Personal Video (or Versatile) Recorders (PVRs). Normally, a PVR is connected between a viewer&#39;s television and that viewer&#39;s cable box, satellite receiver or antenna. The PVR can control the channel tuned on the television, provide an interactive electronic program guide and record programs on a manual or timer-controlled basis. 
         [0005]    The PVR can buffer incoming audiovisual programs so that the viewer can pause a “live” television program or replay a portion of a live television program without missing any subsequent segment of the program, as long as the pause or replay does not exceed the storage capacity of the PVR. Additionally, the PVR can be programmed to regularly record a user&#39;s favorite programs. Consequently, the PVR provides greater flexibility in recording and capturing incoming audiovisual signals than is available with a VCR. 
         [0006]    Within broadcast television programs, advertisements (e.g. television commercials) are interspersed between segments of the audiovisual program and are broadcast as part of the television signal. These advertisements are an important source of revenue for the broadcaster and an important source for the advertiser in reaching current and potential customers with information related to products and services featured in the advertisement. 
         [0007]    However, viewers often consider advertising as a nuisance since they normally want to watch a television program without interruption. Consequently, when a viewer has recorded the program using a PVR, the viewer will tend to fast-forward through the program during commercials or skip ahead. Usually there is no audio playback during a “fast-forward” or “skip” operation. Hence, while the audio is muted, the playback of images is accelerated to minimize the interruption in viewing the recorded program. 
         [0008]    While such “fast-forwarding” and “skip” operations focus the viewing experience on the audiovisual (television) program, they are detrimental to both the advertiser who is trying to reach potential customers and the broadcaster who depends upon advertising for revenue. As a result, there is a need for a system and method that still allow a viewer who has recorded broadcast programs to minimize the interruption caused by interspersed advertisements, while also protecting the broadcaster&#39;s source of revenue.

         [0027]    I. Exemplary System/Device Architecture 
         [0028]    Referring to  FIG. 1A , a first exemplary embodiment of a content delivery system  100  implementing an advertisement control unit within a digital device is shown. One purpose of content delivery system  100  is to deliver content from a content provider to a targeted destination. This targeted designation includes a digital device  110  (e.g., set-top box or PVR) that is in communication with the content provider over an input link  120  to receive digital content that includes advertisements (e.g., video and/or audio) interspersed between segments of an audiovisual program. The advertisements may be delivered in the same channel as the audiovisual program and even within the same data stream. Alternatively, of course, the advertisements may be delivered over a different channel from the audiovisual program. 
         [0029]    According to this embodiment of the invention, digital device  110  is further coupled to a second digital device, such as a television  130  for example, that is adapted to display the content. Digital device  110  includes an advertisement control unit  150  that is adapted to identify, select and/or substitute advertisements geared toward a particular viewer of television  130 . 
         [0030]    Being a wireless controller that is remotely located from digital device  110 , a remote  160  controls the operations of advertisement control unit  150 . Remote  160  is adapted to communicate commands through a communication link  170  established between remote  160  and digital device  110 . In particular, according to this embodiment of the invention, the communication link  170  is a wireless light emitting diode (LED) communication path through which remote  160  sends commands that are formed as light pulses. These light pulses are detected by a LED detector  180  located on digital device  110 . Alternatively, link  170  may be radio-frequency signaling or wireless signaling of other bandwidths where detector  180  constitutes an RF detector. 
         [0031]    As shown, a particular command from remote  160  may be produced by depressing buttons  190  accessible on an outer top surface of remote  160 . Buttons  190  may include a power button, a key of a keypad designating numerals and/or characters, a select button with multidirectional arrows that provide scrolling as needed, or the like. 
         [0032]    Referring now to  FIG. 1B , a second exemplary embodiment of content delivery system  100  implementing advertisement control unit  150  within digital device  110  is shown. Herein, digital device  110  is a device with a display screen  115 . Similar to  FIG. 1A , detector  180  is implemented within a casing  192  of digital device  110 , namely a flat paneled television. Detector  180  detects signals from remote  160  and transfers those signals (e.g. commands) to a processor (MP) located on a back cabinet  193  of television  110 . Herein, the processor receives the commands and issues appropriate signaling to advertisement control unit  150  in order to provide information regarding the viewing audience and/or advertisement selections for substituting advertisements between segments of the audiovisual program as necessary. 
         [0033]    Referring to  FIG. 1C , a third exemplary embodiment of a system implementing advertisement control unit  150  within digital device  110  is shown. Herein, digital device  110  is portable with an integrated display, such as cellular telephone for example. Cellular telephone  110  includes a casing  194 , a user interface  195  (e.g. touch screen, keypad, etc.), a speaker  196  and a microphone  197 . Herein, advertisement control unit  150  may be hardware, firmware or software such as a downloadable application that is executed by a processor implemented within casing  194  of cellular telephone  110 . For that embodiment of the invention, advertisement control unit  150  either can be (i) prestored within local memory of telephone  110  at manufacturer, (ii) stored prior to distribution to the user, or (iii) downloaded into local memory by the user initiating communications with a remote source such as an application server. These communications may be over a private or public network to an application server hosted by any of the following: the cellular telephone service provider, the telephone manufacturer/distributor, or a third party. 
         [0034]    According to one embodiment of the invention, upon downloading advertisement control unit  150  into local memory of telephone  110 , it operates in the background by monitoring and substituting advertisements associated with audiovisual programs played back on telephone  110 . Of course, it is contemplated that advertisement control unit  150  may operate in the foreground in order to provide the user with greater control of the advertisement selection process. 
         [0035]    Referring now to  FIG. 2 , an exemplary diagram of an embodiment of digital device  110  of content delivery system  100  is shown. According to this embodiment of the invention, digital device  110  comprises a power supply unit  200 , a tuner/demodulation unit  210  and data processing unit  220 . Power supply unit  200  is adapted to provide power to tuner/demodulation unit  210  and data processing unit  220 . Power supply unit  200  may provide regulated power based on input power received from a wall socket (e.g., 110 volts alternating current “VAC”, 220 VAC, etc.) or a battery. Tuner/demodulation unit  210  tunes to a channel to receive an incoming digital content and demodulates the content to recover the advertisements and the audiovisual program. The audiovisual program and the advertisements are routed as a digital bit stream to data processing unit  220 . 
         [0036]    According to one embodiment of the invention, data processing unit  220  comprises a processor  230  and/or a decoder  240 . These components may be implemented as separate integrated circuits or as a single integrated circuit. As described herein, data processing unit  220  features logic operating to decode and process incoming information as well as advertisement control unit  150  that is adapted to alternatively select the genre and source of advertisements that are fetched/filtered and stored within digital device  110  for subsequent playback during viewing of the audiovisual program. An input unit  250  may be implemented as an integral part of digital device  110  or may be separate and remotely located from digital device  110  (not shown). 
         [0037]    In general, according to one embodiment of the invention, advertisement control unit  150  is adapted to generate user interfaces for registration purposes and to replace broadcast advertisements with advertisements fetched from a data storage unit  260  that operates as local memory for digital device  110 . The replacement scheme may involve tags within the broadcast program to identify what advertisements are to be fetched from data storage unit  260 . Another replacement scheme may involve data processing unit  220  accessing metadata within an Adaptation field of one or more Motion Picture Experts Group (MPEG) packets associated with an advertisement in order to provide signaling to advertisement control unit  150  regarding the genre or subject matter of the advertisement. This metadata allows advertisement control unit  150  to determine whether the genre or subject matter of the advertisement is preferred by the viewer for playback on a display unit  270 . Display unit  270  may be implemented as an integral part of digital device  110  or may be separate and remotely located therefrom (not shown). 
         [0038]    For instance, as shown in  FIG. 3A , an exemplary diagram of an adaptation field  310  of an I-frame  300  is shown. Adaptation field  310  is a portion of a MPEG packet  305  of a digital data stream, where according to this embodiment, MPEG packet  305  is associated with an advertisement to be displayed. Adaptation header  310  features control information  315  to indicate (i) whether an advertisement playback feature is enabled, and/or (ii) the genre of the advertisement. 
         [0039]    More specifically, according to this particular embodiment of the invention, adaptation header  310  comprises control information  315  that includes at least one bit to indicate whether the advertisement playback feature is enabled. This enables the digital device to operate in two or more modes, where at least one mode is designed to prevent fast-forwarding as well as skipping/pausing/muting of advertisements (e.g., advertisement playback feature). For instance, when control information  315  includes three bits, the digital device may operate in eight or less modes. Of course, more bits may be utilized to support a greater number of operating modes as shown in Table A where 5 bits (up to 32 modes) may be supported.

         [0040]    As set forth in  FIG. 3B , control information  315  of adaptation header  310  comprises a plurality of sub-fields, including but not limited or restricted to one or more of the following: (1) advertisement type sub-field  330 ; (2) advertisement replacement type sub-field  340 ; and (3) advertisement playback sub-field  350 . 
         [0041]    Advertisement content type sub-field  330  identifies the genre of advertisement intended for display. This information may be used by advertisement control unit  150  of  FIG. 2  to select various types of replacement advertisements, if advertisement replacement is supported. 
         [0042]    Advertisement replacement type sub-field  340  identifies the type of replacement schemes that are available in response to detection of an accelerated playback of an advertisement (e.g., fast-forwarding and/or skipping) by the advertisement control unit. For instance, in response to a particular action to reduce the viewing time of the advertisement (e.g., ×30 FF or skip), the advertisement control unit may substitute the advertisement with a different full-length advertisement previously selected by the user. Alternatively, the advertisement control unit may cause the digital device to operate in an abbreviated mode in which a partial-length audiovisual advertisement(s) or an advertisement with static image(s) is substituted for the broadcast advertisement(s). These “abbreviated” advertisements have a display time that is less than the normal fifteen or thirty seconds allocated for broadcast advertisements. 
         [0043]    Advertisement playback sub-field  350  identifies whether there are restrictions against altering of a broadcast advertisement (e.g., fast-forwarding, skipping, pausing, muting, etc.), and if so, to what degree are such alterations permitted as shown above in Table A. 
         [0044]    Alternatively, it is contemplated that the control information may be placed in another location within the content stream other than the adaptation header  310  of  FIG. 3A . For instance, as shown in  FIG. 3C , the control information may be placed within a tag  360  that precedes one or more advertisements. Tag  360  includes information that (1) identifies the genre of advertisement intended for display; (2) identifies the type of replacement schemes that are available in response to detection of an accelerated playback of an advertisement; (3) identifies whether there are restrictions against altering of a broadcast advertisement (e.g., fast-forwarding up to “m×” or “n×” times playback speed where m,n&gt;1, skipping, pausing, muting, etc.); or any combination thereof. For instance, if there are restrictions, the information further indicates what alterations are permitted. As an example, the advertisement may allow for 2× or 8× fast forwarding, but in response to a fast forwarding operation of 30× or more, a static advertisement is displayed for a few seconds. 
         [0045]    Referring to  FIG. 4A , an exemplary embodiment of a user interface produced by advertisement control unit  150  of digital device  110  of  FIG. 2  to commence registration of one or more viewers is shown. Herein, a registration image  400  is displayed by digital device  110  in order to allow the viewer or viewers to provide personal information. Herein, a viewer can use a remote or keypad associated with digital device  110  in order to enter alphanumeric characters that will provide some or all of the following information concerning the viewer(s): (1) name  410 ; (2) age  415 ; (3) gender  420 ; (4) ethnicity  425 ; and (5) income level  430 . 
         [0046]    For some of the viewer-based information, pull-down menus may be provided to allow the viewer to select the appropriate entry. For instance, as shown, a pull-down menu  440  may be provided with two entry selections: male “M” and female “F”. Additionally, pull-down menus may be provided for some of the other categories such as age, ethnicity, and income level. The “name” category however will most likely be input by the viewer via buttons on a remote or those associated with a digital device or an input mechanism integrated on digital device  110  such as a keypad, a touch screen, or the like. 
         [0047]    Referring now to  FIG. 4B , an exemplary embodiment of a user interface  450  produced by the advertisement control unit of the digital device to program the preferred advertisements for a first viewer is shown. Herein, user interface  450  provides a plurality of parameters for use in selecting preferred advertisements. For instance, as an example, these parameters include, but are not limited or restricted to a genre parameter  460 , a source parameter  470  and a parental control parameter  480 . 
         [0048]    Genre parameter  460  is used to identify particular types of advertisements that the viewer would like to see interspersed between television programming. Source parameter  470  provides information from where the digital device is to fetch the advertisements. Parental control parameter  480  provides a mechanism to exclude certain types of advertisements from being displayed on the digital device. For instance, the parental controls may be viewer specific to exclude the displaying of a type of advertisement when a particular viewer is watching or may be generally applied to excluding this type of advertisement from being displayed on the digital device. 
         [0049]    Referring now to  FIGS. 5A-5C , exemplary embodiments of selectable user interfaces produced by the advertisement control unit of the digital device in order to program the preferred genre of the advertisements is shown. Herein,  FIG. 5A  illustrates a first user interface  500  of advertisement genre that is selectable by the viewer. According to this embodiment of the invention, the advertisement genre includes, but is not limited or restricted to financials  502 , sports  504 , beverages  506 , electronics  508 , automotive  510 , fashion  512 , furniture  514 , health  516  and other  518 . Herein, the viewer selects the genre of advertisements that he or she would be willing to watch in full or in an abbreviated mode in order to customize the advertisement viewing for that particular user. 
         [0050]    According to one embodiment of the invention, at least one genre is required to be selected before proceeding to the next user interface of the advertisement selection scheme. Herein, the beverage and automotive categories  506  and  510  are selected by the viewer. In event that the “other” category  518  is selected, another selectable user interface (e.g., screen display) with additional advertisement genres is displayed for the viewer to choose different categories for this particular genre. 
         [0051]    Of course, in lieu of selecting the particular genres that are acceptable to the viewer, interface  500  may be adapted so that all of the genre categories are selected. Now, the viewer would need to deselect the particular genre category or categories that he or she does not want to view. 
         [0052]    Referring to  FIG. 5B , a second user interface  530  is provided which provides greater granularity as the particular types of automotive advertisements that would be available to the viewer. Herein, according to one embodiment of the invention, the automotive advertisements are categorized according to the make of a particular type of automotive vehicle such as, for example, Lexus®  532 , Acura®  534 , Ford®  536 , BMW®  538 , Volvo®  540 , Cadillac®  542 , Honda®  544 , Subaru®  546  and Other  548 . According to another embodiment for this user interface, the automotive advertisements may be categorized according to make/model of these automotive vehicles. 
         [0053]    In the event that the viewer selects one of the “make” categories illustrated in  FIG. 5B , such as the Lexus® category for example, an additional user interface  550  is provided as shown in  FIG. 5C . Of course, user interface  550  may be produced automatically or in response to selection of an entry (not shown). As shown, for this embodiment of the invention, user interface  550  is a selectable screen display that allows the user to select the particular “model” of the vehicle for which advertisements will be played back for the viewer. For this illustrative example, Lexus® LS460 and Lexus® ES350 sedans are selected. 
         [0054]    If none of the vehicle models are selected, all Lexus® models will be selected by default in order to comply with the viewer&#39;s request for Lexus® advertisements in user interface  530  of  FIG. 5B . Similarly, for the automotive “makes” set forth in  FIG. 5B , in the event that none of these are selected by the viewer, the advertisement control unit enters into a default state where all automotive makes are selected in order to comply with the viewer&#39;s request for automotive advertisements in user interface  500  of  FIG. 5A . 
         [0055]    Referring now to  FIGS. 6A and 6B , user interfaces  600  and  630  are shown in order to allow the viewer to select the particular source upon which the advertisements may be extracted. As shown in  FIG. 6A , user interface  600  displays the sources from which advertisements can be recovered or obtained. These sources may include, but are not limited or restricted to a particular content provider  610  or various websites accessible over the Internet  620 . Upon selecting advertisements from the content provider, advertisements periodically may be uploaded to the digital device therefrom and stored in local memory for subsequent retrieval. The periodicity of the uploading may be on a daily basis or with greater periodicity such as on an hourly basis. 
         [0056]    Upon selecting the Internet parameter, a user interface  630  is generated, which is illustrated as a screen display that lists websites  640  and  645  from which the advertisements may be downloaded. These websites  640  and  645  may be dedicated websites for particular advertisers or websites of particular content providers or broadcasters. Alternatively, the websites may be a video based website from which revenue could be realized by the broadcasters from advertisements extracted from that particular website. 
         [0057]    Referring to  FIG. 7 , an exemplary embodiment of the parental control user interface  700  is shown. Herein, various adult-oriented genres  710  are listed to enable a guardian of the viewer to select particular genres or advertisement categories that the viewer should not be allowed to view. For instance, such categories may include, for example, male enhancements  715 , feminine hygiene products  720 , wine &amp; spirits  725 , breaking news commercials  730  which are normally geared toward sensationalism, and the like. By selecting any of “parental control” genre, the advertisement control unit prevents such genre from being displayed. 
         [0058]    Referring now to  FIGS. 8A-8C , exemplary embodiments of selectable user interfaces produced by the advertisement control unit of the digital device in order to program the preferred genre of the advertisements according to a rating scheme is shown. Herein,  FIG. 8A  illustrates a first user interface  800  of advertisement genre that is selectable by the viewer. According to this embodiment invention, the advertisement genre includes, but is not limited or restricted to financials  802 , sports  804 , beverages  806 , electronics  808 , automotive  810 , fashion  812 , furniture  814 , health  816  and other  818 . Herein, the viewer selects the genre of advertisements that he or she would be willing to watch in full or abbreviated mode in order to customize the advertisement viewing for that particular user. 
         [0059]    According to one embodiment of the invention, at least one genre is required to be selected before proceeding to the next segment of the advertisement selection scheme. Herein, the automotive and fashion categories  810  and  812  are selected by the viewer. As previously described, in event that an “other” category  818  is selected, another user interface (e.g., screen display) with additional advertisement genres is displayed for the viewer to select different categories for this particular genre. Alternatively, in lieu of selecting the particular genres that are acceptable to the viewer, user interface  800  may be adapted so that all of the genre categories are selected. Now, the viewer would need to deselect the particular genre category or categories that he or she does not want to view. 
         [0060]    Referring to  FIG. 8B , a second user interface  830  is provided which provides greater granularity as to the particular types of automotive and fashion advertisements that are acceptable to the viewer. Herein, according to one embodiment of the invention, the automotive advertisements are categorized according to the make of a particular type of automotive vehicle such as, for example, Lexus®  832 , Acura®  834 , Ford®  836 , BMW®  838 , Volvo®  840 , Cadillac®  842 , Honda®  844 , Subaru®  846  and Other  848 . The fashion advertisements are categorized according to clothing maker, clothing type and/or store such as Victoria Secret®  850 , Hanes®  852 , swimsuit  854 , dresses  856 , Saks Fifth Avenue  858 , Nordstrom  860 , and other  862 . 
         [0061]    Instead of selecting the categories, the viewer can use the remote or input unit to provide preference ratings for each of these categories. For instance, according to this example, Lexus® and Acura® advertisements are rated “1” and “2” by depressing a corresponding numeral on the keypad of the remote while Victoria Secret advertisements was rated “3”. Further granularity of advertisements may be provided as described above, where each category provides sub-categories for the user to select. 
         [0062]    As shown in  FIG. 8C , for this embodiment of the invention, user interface  870  is a selectable screen display that allows the user to select the particular “model”  880  of the vehicle for which advertisements will be played back for the viewer. If none of the vehicle models are selected, all Lexus® models will be selected by default in order to comply with the viewer&#39;s request for Lexus® advertisements in user interface  830  of  FIG. 8B . 
         [0063]    Referring to  FIG. 9 , after a viewer has registered his or her advertisement preferences, the advertisement control unit provides a control panel that identifies which registered viewer(s) is(are) currently watching the program. According to this embodiment of the invention, a control panel  900  is superimposed over an audiovisual program  910  that is being watched. Control panel  900  is used to determine the current viewing audience in order to provide appropriate controls signals to the advertisement control unit for advertisement selection. 
         [0064]    Herein, control panel  900  includes one or more selectable entries  920  that are each associated with a registered viewer and designate which of the registered viewers form the viewing audience. An additional entry  930 , when selected, begins registration of a new viewer. Upon selection of an entry associated with a registered viewer, the advertisement control unit is provided information that the registered viewer is part of the viewing audience. Hence, the advertisements will be tailored to the viewing audience. Control panel  900  may be displayed at initial power-on of the digital device and may be intermittently displayed automatically or in response to commands initiated by the viewer via the remote or a panel located on the digital device itself. 
         [0065]    In the event that the viewing audience is identified as consisting of multiple registered viewers, the advertisement control unit determines if there is a subset of advertisements that are preferred by the entire viewing audience. In the event that the viewers substantially differ in advertisement preferences, and thus no subset can be computed, the advertisement control unit selects those advertisements that are preferred by any of the registered users. The advertisements may be pseudo-randomly selected or may be selected according to a particular pattern. For instance, the advertisements may be intermixed so that the first advertisement is of a genre preferred by the first viewer while the second advertisement is of a genre preferred by the second viewer, and the like. 
         [0066]    If parental controls are in place for at least one of the viewers or for the digital device in general, the genre of advertisements that have been disallowed from viewing will not be shown, even if one of the viewers has such advertisements as part of his or her preferences. Besides mere selection of entries by the viewers, passwords may be required where parental controls are in effect. 
         [0067]    Control panel  900  may also be used to remove a registered viewer from the viewing audience by deselecting the viewer who now will not be part of the viewing audience. As an example, this would remove a designation (e.g. underline, highlight, etc.) from the viewer&#39;s listed name. As a result, the advertisements may be specifically tailored to the remaining viewer(s). 
         [0068]    Of course in lieu of viewer registration, it is contemplated that the registration process could be directed toward a category of users such as “adults” and “minors” for instance. In this situation, the viewer can be tailored to a broad category of viewers. 
         [0069]    Having disclosed exemplary embodiments and the best mode, modifications and variations may be made to the disclosed embodiments while remaining within the scope of the embodiments of the invention as defined by the following claims.
