    Abstract: A system and method for managing media quality is provided. The system includes a data store with a computer readable medium storing a program of instructions for the managing of media quality; a processor that executes the program of instructions; a media analysis unit to receive transcoded media from a media store, and to detect for a phenomena affecting the transcoded media; a media quality manager, in response to the media analysis unit detection of the phenomena, determining a parameter for transcoding media; and a re-transcode unit to re-transcode the transcoded media based on the parameter.

    Abstract: The present disclosure provides systems and methods that select programming information for inclusion in informational displays. In one example, for a particular instance of content stream associated with a content distributor carrying a version of the program at a particular air time, the information retrieval system can determine whether such instance constitutes local programming or national programming. As one example, the system can determine whether a first version of a program is local programming or national programming based at least in part on a comparison of a first content stream that includes the first version of the program with at least one other content stream that is associated with a same content distributor and also associated with a time zone associated with a user.

    Abstract: Adaptive video transcoding based on parallel chunked log analysis is described. The adaptive video transcoding method comprises receiving an intermediate video stream generated from an intermediate transcoding. The method also receives an intermediate transcoding log stream associated with the intermediate video stream. The method partitions the intermediate video stream into a plurality of video chunks, where each video chunk corresponding to a portion of video data of the video stream. The method further generates video chunk statistics for each of the video chunks using the intermediate transcoding log stream and transcoding parameters for each of the video chunks based on the generated video chunk statistics. The method transcodes each of the video chunks to a target format in parallel based on the generated transcoding parameters. The method assembles the transcoded video chunks into a target video stream in the target format.
