Abstract: A session management involves registering at least one IPTV application in a registration table so that the registration table includes at least a respective identifier of the IPTV applications. The IPTV applications are invokable at a set top box and can be so-called embedded applications and/or browser-based applications. An event requiring the invocation of an IPTV application at the set top box is detected and triggers a look-up in the registration table. The registration table is thus used as source to indicate those IPTV applications that are potentially available and can be launched at the set top box. One of the registered applications is launched for the purpose of handling the detected event.

Abstract: A media system replaces content in a first sequence of media content. The media system presents the first sequence of media content to an end-user and generates a fingerprint of the sequence of media content. The fingerprint is for comparison with a plurality of reference fingerprints so as to identify the first sequence of media content and determine a reference position within the first sequence of media content. The media system sends a request for a replacement sequence of content to a content replacement system, and receives replacement media content selected based on the identified first sequence of media content. The media system presents the replacement media content to the end-user instead of the first sequence of media content. Presenting the replacement media content begins at a position in the first sequence of media content that is determined based on the reference position.

Abstract: Various embodiments of systems, apparatus, and/or methods are described for selectively obscuring a rendering of a media stream.

A content identifier is identified for an event within the requested media stream. Based upon the content identifier, it may be discovered that the event is accessible through at least one second media source. The rendering of the requested media stream may then be obscured and a notification provided to a user that the event within the requested media stream is accessible through at least one second media source.

Abstract: An electronic device associated with a media-providing service obtains listening history for a media item. The listening history includes retention information that indicates a number of listeners who listened to the respective portion of the media item. Using the retention information, the electronic device generates a retention graph that represents the number of listeners who listened to corresponding portions of the media item as a function of time. The electronic device detects an extremum in the retention graph. The extremum corresponds to a reduction in the number of listeners who listened to the corresponding portions of the media item. The electronic device determines whether the extremum meets predefined criteria, and in accordance with the determination that the extremum meets the predefined criteria, the electronic device stores an indication that the portions of the media item corresponding to the extremum include sub-content embedded in the media item.

Abstract: Systems, apparatus, and methods are described for responding to inoperative commands on a server device. In some embodiments, the disclosed technology facilitates pausing of content being played on a device without creating a bookmark of the location in the content at which the content was paused. In response to receiving the request to pause the content from playing, the server device generates a pause instruction to pause the content from playing. Upon expiry of a timeout interval, the server device automatically transforms the pause instruction into a stop instruction, which when executed causes stopping the content from playing. In some embodiments, the server device detects an user interaction event, prior to expiry of the timeout interval. Non-limiting examples of the user interaction may be shutting down the server device, switching from the content to a live broadcast program, switching from the content to another content, or exiting from the content.

Abstract: Various implementations described herein are directed to determining variations or changes to a predetermined programming schedule. In accordance with one method, a predicted end time of video content may be determined to be later than a scheduled end time of the video content. Also, it may be determined that video content scheduled to be displayed on a first stream or channel has been moved to a second stream or channel. A scheduled recording or transmission time of video content may be altered based on detected changes to the predetermined programming schedule. A program listing such as an electronic program guide may be revised based on detected changes to the predetermined programming schedule.
