       [0001]     IBM® is a registered trademark of International Business Machines Corporation, Armonk, N.Y., U.S.A. Other names used herein may be registered trademarks, trademarks or product names of International Business Machines Corporation or other companies.  
       BACKGROUND OF THE INVENTION  
       [0002]     1. Field of the Invention  
         [0003]     This invention relates to interactive digital media systems, and particularly to methods, systems, and computer program products for facilitating interactive programming services.  
         [0004]     2. Description of Background  
         [0005]     One area within home entertainment that has received press as an emerging market is the future capabilities of interactive television. Integrating large video-processing power for advanced multiprocessing devices into television sets enables some desirable functions, allowing user controlled manipulation of multiple varying viewpoints (camera angles).  
         [0006]     A user who is given an option of manually switching between multiple camera angles might likely feel overwhelmed, and as a result, may prefer to avoid using the function, rather than attempt to navigate among so many options.  
         [0007]     What is needed, therefore, is a way to facilitate the selection and use of multiple programming viewpoints by automating switching among viewpoint sources based upon criteria such as user preferences (e.g., as configured via rules and via behavior analysis and tracking) and group and/or social paradigms established among a set of users.  
       SUMMARY OF THE INVENTION

The method includes providing a selection of viewpoints for perceiving a program event. Each of the viewpoints provides a unique perspective of the program event. The viewpoints are simultaneously transmitted to a digital media system as a single programming event, which is one of a plurality of programming events that collectively form a program. The method also includes providing criteria selectable for determining which of the viewpoints to present via the digital media system, receiving at least one response to the criteria, and selecting a viewpoint to present based upon the at least one response. The method further includes presenting the program event, the program event exhibited from the selected viewpoint.  
         [0009]     Additional features and advantages are realized through the techniques of the present invention.

       [0016]     The detailed description explains the preferred embodiments of the invention, together with advantages and features, by way of example with reference to the drawings.  
       DETAILED DESCRIPTION OF THE INVENTION  
       [0017]     In accordance with exemplary embodiments, interactive programming services are provided. Programming content delivered to a digital media system includes multiple viewpoints or perspectives of the content, which is selectable by a viewer and/or a viewing population. The interactive programming services enables a viewer and/or viewing population to select the display or presentation of preferred viewpoints of the content via an automated rule-based component of the services. The viewpoint selection may be generated via a user profile that includes rules and conditions for determining which viewpoint is presented. The interactive programming services also enable a user to become part of a larger user/viewer group, either a location-based group (that is defined by the group members) or a community group that is defined by the service provider of the interactive programming services.  
         [0018]     A viewpoint refers to a portion of content or programming that provides a particular perspective of the content (e.g., a camera that records the content from a particular angle at a fixed location, a roving camera that follows a particular object or event, a camera that is fixed to a particular object or individual, etc.) A viewpoint may also refer to a measure of distance from an object or event that is part of the program. Thus, a viewpoint may be location based and/or object based. The content, including the multiple viewpoints, is transmitted to multiple receiving locations as described further herein.  
         [0019]     Turning now to  FIG. 1 , a system upon which the interactive programming services may be implemented in exemplary embodiments will now be described. The system of  FIG. 1  includes a host system  102  in communication with a digital media system  104  via one or more networks  106  and a set top box  108 .  
         [0020]     Host system  102  may comprise any high-speed processing device, e.g., a mainframe computer that is capable of handling large volumes of processing activities. In exemplary embodiments, host system  102  is implemented by a digital content service provider that provides programming services to customers, such as a user of digital media system  104 , for a fee. Content provided by the host system may include, e.g., television programming (such as sporting events, movies, pay-per-view programs, music, etc.). In addition, host system  102  may also provide multi-media communications services, such as Internet access, web browsing, email, instant messaging, video chat, interactive gaming, etc. Additionally, host system  102  facilitates the interactive programming services described herein.  
         [0021]     Digital media system  104  refers to a device via which a user can receive content (e.g., programming). For example, digital media system  104  may be an Internet Protocol (IP)-enabled television (IPTV), a personal computer, or other similar type of device. The digital media system  104  is communicatively coupled to the set top box  108 , which may include hardware and/or software for handling user requests to utilize various multi-media services via a broadband Internet connection. Network  106  may comprise a switched telephone or cable network.  
         [0022]     In exemplary embodiments, digital media system  104  includes a central processing unit (CPU)  110 , or processor, and an input device  112 . In exemplary embodiments, CPU  110  comprises a micro-processor or advanced processing device for implementing the interactive programming services described herein. For example, CPU  110  may comprise a Cell multiprocessor that provides an advanced chip architecture design that uses high-speed broadband connectivity. The Cell multiprocessor is the result of a joint development project by Sony Computer Entertainment Inc., International Business Machines Corp., and Toshiba Corp. Input device  112  may comprise a remote control, a keyboard, mouse, buttons onboard the digital media system  104 , etc.  
         [0023]     CPU  110  executes one or more applications via the digital media system  104 . Communications applications such as email (not shown) and instant messaging  116  may be implemented via CPU  110  and the digital media system  104 . In addition, an application for implementing the interactive programming services may be executed by CPU  110 . This application is referred to herein as a viewpoint control application  118 . The viewpoint control application  118  includes a user interface  120 , both of which will be described further herein.  
         [0024]     Also shown in  FIG. 1  is a personal video recorder (PVR)  114 . PVR  114  refers to a device that is internal or external to the digital media system  104  and which records/plays back programs or other content on behalf of a user of the digital media system  104 . For example, PVR  114  may record programs transmitted via the host system  102  and played back on the digital media system  104  at a later time.  
         [0025]     The digital media system  104  of  FIG. 1  further includes storage  122  for housing information utilized by the viewpoint control application  118 . Storage  122  may comprise internal memory (i.e., main memory) built into the digital media system  104  or may be external, or secondary storage, located outside of the digital media system  104 . In exemplary embodiments, storage  122  houses user profiles and/or group profiles generated via the viewpoint control application  118 . A user profile provides particular preferences supplied by a user of the digital media system  104  via the viewpoint control application  118 . The user&#39;s individual preferences are stored in the user profile and are accessible via the viewpoint control application  118  for use in implementing the individual rule-based automation features, which are described further in  FIG. 2 .  
         [0026]     Group preferences refer to the collective preferences of a group of users that may be viewing a particular program at a single location (e.g., user&#39;s home) or may be two or more users viewing a particular program at different locations but who wish to experience the program via the same viewpoints. For example, two users are each viewing a program from a different location and are also experiencing the program, e.g., via instant messaging, telephone, or other communication means. The group features of the viewpoint control application  118  are described further herein.  
         [0027]     Storage  122  may also house information tracked by the viewpoint control application  118  that relates to user activities with respect to manual viewpoint switching (e.g., when a user physically selects a different viewpoint during a program). These behaviors are tracked and monitored by the viewpoint control application  118  in order to implement rule-based automation features via behavioral analysis, which is described further in  FIG. 4 .  
         [0028]     The viewpoint control application  118  provides a user-configurable rule set to dictate or influence which viewpoint is used for particular situations. This is facilitated by the user profile. By way of example, suppose in a football game, each player&#39;s helmet is embedded with a camera. Suppose also that there are various sideline cameras, end zone cameras, and even a coach-cam. Each viewer may wish to watch the game from a different perspective during particular situations. The user may configure this rule set to specify which camera or viewpoint to use when particular criteria are met with the program. The user may configure one rule within the rule set to tell the system to use the normal sideline camera during most situations, but switch to the camera of the nearest wide receiver when a ball is thrown, and further, use the goalpost camera when the ball is within ten yards of the end zone. In another example, suppose a user watching an Academy Awards show prefers a front-row camera view during musical performances, but a more standard angle during awards announcements.  
         [0029]     To aid in the rule-based functionality provided by the viewpoint control application  118 , producers of programming may provide a priority list of camera angles and specify how these angles are ranked according to the level of their involvement with a particular programming event or artistic effect of the content. The top ranked viewpoint or angle may be specified as the default viewpoint, and the bottom ranked viewpoints may not even show the programming. This allows a user to specify exceptions to rules to prevent switching to a camera that is out of the top rankings. Other rules may utilize a preference or exclusion of a particular camera or viewpoint or a preference toward viewpoints that show a particular object or individual.  
         [0030]     The programming event, as described herein, may be a segmented portion of the program and may be defined using various criteria. For example, a programming event for a basketball game may be a foul shot resulting from an earlier issued penalty. A first viewpoint of this programming event may be a close up of the shooting player, while a second viewpoint of the same event may be taken from above the backboard. A third viewpoint of the same programming event may be a side view of the shooting player taken from the sidelines of the basketball court that is closest to the hoop.  
         [0031]     As indicated above, some of the preferences may be based upon an object or individual in view. For example, if a user is watching a reality show and is interesting in observing their favorite contestant, their rule may include choosing a camera angle that most frequently shows this contestant. This may be implemented via tags inserted, e.g., by the show&#39;s producers. Alternatively, the viewpoint control application  118  may analyze the video frames to determine which cameras include the character in question. This information may then be used by the rules to present to the user the viewpoint options that include the contestant and allow the user the ability to manually switch from a currently displayed viewpoint to an appropriate viewpoint in order to view the contestant. Additionally, by analyzing the video frames in recorded media (e.g., content stored on PVR  114  or hard drive), the viewpoint control application  118  would indicate to the user which viewpoint will contain the desired object or individual in a specified time period. The viewpoint control application  118  may include the ability to override the default viewpoint settings or proactively switch to a desired viewpoint in anticipation of an upcoming action.  
         [0032]     Also shown in the system of  FIG. 1  is a storage device  124 . Storage device  124  stores information utilized by the host system  102  in furtherance of providing the interactive programming services. For example, storage device  124  stores subscriber accounts, community lists, and community profiles, each of which will be described further herein. As shown in  FIG. 1 , storage device  124  is in communication with host system  102  via network  106 . However, it will be understood by those skilled in the art that the storage device  124  may be directly coupled to the host system  102  (e.g., via cabling or wireless means).  
         [0033]     Turning now to  FIG. 2 , a flow diagram describing a process for implementing individual rule-based automation features of the interactive programming services in exemplary embodiments will now be described. The process begins at step  202  whereby the viewpoint control application  118  queries program data received at the digital media system  104  in light of a user-configured rule provided in the rule set stored in the user profile at step  204 . Based upon the query, it is then determined whether a condition of the rule has been met at step  206 . If so, the viewpoint control application  118  applies the rule to the program at step  208 . For example, the user profile includes a rule that specifies some action if musical performance is scheduled to occur within the program. The condition specifies a desired viewpoint or camera angle for presenting the musical performance. Since the condition has been met (once the performance is set to commence), the viewpoint control application  118  switches to the desired viewpoint.  
         [0034]     At step  210 , it is then determined whether any additional program data remains for query (i.e., is there additional programming matter to be presented). If so, the process returns to step  204 . Otherwise, the process ends at step  212 .  
         [0035]     Returning to step  206 , if the condition of the rule has not been met, it is determined whether any other rules exist in the rule set at step  214 . If so, the viewpoint control application  118  selects the next rule in the rule set and the process returns to step  206 . If, on the other hand, there are no other rules in the rule set, the process proceeds to step  210  whereby the viewpoint control application  118  determines if any additional programming data remains for query. If so, the process returns to step  204 . Otherwise, the process ends at step  212 .  
         [0036]     Turning now to  FIG. 3 , a flow diagram describing a process for implementing rule-based group features of the interactive programming services in exemplary embodiments will now be described. For purposes of illustration, assume that three individuals are present at a location where the digital media system  104  is situated, where a program has commenced. At step  302 , a program event and various corresponding viewpoints associated with the event are identified by the viewpoint control application  118 . The viewpoint control application  118  polls each group member for a viewpoint preference with respect to the available viewpoints at step  304 . At step  306 , the most popular viewpoint of the group members is determined as a result of the polling.  
         [0037]     At step  308 , it is determined whether the most popular viewpoint is different than that of the currently displayed or referenced viewpoint (e.g., are the two viewpoints originating from the same camera). If not, the viewpoint control application  118  waits a specified period of time at step  310  and the process returns to step  302 . Thus, the viewpoint control application  118  maintains the current viewpoint for display. If, on the other hand, the two viewpoints are not the same, it is next determined whether a percentage of users sharing the popular viewpoint exceed a specified threshold at step  312 . For example, a user may set a threshold that specifies what percentage of users are required to share the same popular viewpoint before the viewpoint control application  118  will switch to the popular viewpoint for display on the digital media system  104 . If the threshold has not been met, the viewpoint control application  118  waits a specified period of time at step  310  and the process returns to step  302 . If the percentage meets or exceeds a specified threshold, the viewpoint control application  118  causes the programming to switch to the most popular viewpoint at step  314 . The viewpoint control application  118  waits a specified period of time at step  310  and the process returns again to step  302 .  
         [0038]     As indicated above, a community-based feature may be implemented by the interactive programming services. As some viewers may prefer more discrete manual or rule set-defined controls over which viewpoints to use under certain situations, other users may prefer an easier solution. Instead of relying on default viewpoints provided by the programming, the viewpoints presented may reflect the input of a larger community of users. For example, if 60% of users switched to camera B during a particular play during a sporting event, a user who is relying on community input may have his/her own viewpoint switched to the same camera if, e.g., a threshold value is met. The community-based features may be implemented via the viewpoint control application  118  and the host system  102 , which receives these selections from users who wish to be included in a community group (e.g., the group of users viewing the sporting event). The user provides these preferences to the host system  102  via, e.g., the digital media system  104  using input device  112 , viewpoint control application  118 , and user interface  120 , which provides user-selectable options that may be presented on a display element of the digital media system  104 .  
         [0039]     Turning now to  FIG. 4 , a flow diagram describing a process for implementing rule-based automation features via behavioral analysis of the interactive programming services in exemplary embodiments will now be described in accordance with exemplary embodiments. The rule-based automation features that utilize behavior analysis provide an intelligent solution for creating and/or modifying rules in a user&#39;s rule set. The processing provided in the flow diagram of  FIG. 4  may supplement some or a portion of the activities performed in  FIG. 2 .  
         [0040]     At step  402 , the viewpoint control application  118  monitors user behavior with respect to program viewing and viewpoint selection. At step  404 , it is determined whether a manual change of viewpoint has been initiated by a user. If not, the process returns to step  402 . Otherwise, the viewpoint control application  118  collects program data at step  406  for the program events associated with the manual change in viewpoint selection. For example, if the program event involves a viewpoint change relating to a foul shot taken by a player during a basketball event, the program data surrounding the event (i.e., foul shot, player number, team, etc.) may be captured by the viewpoint control application  118 . The program data and viewpoint data (i.e., the particular viewpoint selected by the user as a result of the manual change) are logged into a database at step  408 . At step  410 , the viewpoint control application  118  queries the database for similar entries.  
         [0041]     At step  412 , it is determined whether the number of similar entries exceeds a specified threshold. For example, the viewpoint control application  118  determines whether the history of user activity constitutes a pattern of activity that is sufficient to warrant further action. If not, the process returns to step  302 . Otherwise, the user is prompted to create a new rule at step  414 . For example, the new rule may specify that future program events that depict foul shots be presented from a particular viewpoint. At step  416 , it is determined whether the user has accepted the invitation to create a new rule. If not, the process returns to step  402 . Otherwise, the viewpoint control application  118  creates a new rule via the user&#39;s input at step  418 .  
         [0042]     The capabilities of the present invention can be implemented in software, firmware, hardware or some combination thereof.  
         [0043]     As one example, one or more aspects of the present invention can be included in an article of manufacture (e.g., one or more computer program products) having, for instance, computer usable media. The media has embodied therein, for instance, computer readable program code means for providing and facilitating the capabilities of the present invention. The article of manufacture can be included as a part of a computer system or sold separately.  
         [0044]     Additionally, at least one program storage device readable by a machine, tangibly embodying at least one program of instructions executable by the machine to perform the capabilities of the present invention can be provided.  
         [0045]     The flow diagrams depicted herein are just examples. There may be many variations to these diagrams or the steps (or operations) described therein without departing from the spirit of the invention. For instance, the steps may be performed in a differing order, or steps may be added, deleted or modified. All of these variations are considered a part of the claimed invention.  
         [0046]     While the preferred embodiment to the invention has been described, it will be understood that those skilled in the art, both now and in the future, may male various improvements and enhancements which fall within the scope of the claims which follow. These claims should be construed to maintain the proper protection for the invention first described.
