Abstract: Methods, systems, and computer readable media can be operable to facilitate the mapping of packet identifiers to a constant value. A multimedia device may receive one or more pieces of multimedia content and may select a constant PID value for each of one or more component streams associated with the content. The multimedia device may map PIDs of each respective one of the one or more component streams to a constant PID value designated for the component type of the respective component stream. The multimedia device may replace the PIDs of each component stream with constant PID values such that each component stream type includes the same PID value for the entirety of the stream. The modified component streams, each having continuity with respect to PID values, may be stored as a recording or output to a device for viewing.

Abstract: Methods, systems and computer readable media may facilitate the repositioning of content based upon scene boundaries. In embodiments, content may be automatically repositioned at a scene boundary, so that the content presentation starts from a more meaningful and sensible point after a re-position (e.g., time-shift, trickplay, seek, etc.). Also provided herein is an approach to provide an option for the user to start playback of content from an absolute time based repositioned point or a scene based repositioned point. Scene change detection may be used to detect scene changes within a piece of multimedia content as the content is being received, played, or recorded by a device. Scene changes within a piece of content may be identified using scene meta-data created on a per content basis, wherein the meta-data includes the starting frame offset of each scene along with the duration of the scene.

Abstract: A method is provided to presenting contextual information during adaptive bitrate streaming to allow play of an audio-only variant. The method includes receiving an audio-only variant of a video stream, calculating bandwidth headroom, receiving contextual information that provides descriptive information about visual components of the video stream that has a bitrate less than the bandwidth headroom, and presenting the contextual information to users while playing the audio-only variant.

Abstract: Systems and methods for a self-correcting DVR record pipeline may provider for simpler, lower cost transport producer hardware elements. A free running transport pipeline producer may fill transport buffers without waiting for feedback from the data consumer that data has been completely processed. The pipeline data consumer independently detects transport buffers that are overwritten before processing on the buffer content is complete. The pipeline data consumer drops or deletes any invalid content or stream data to recover from the data overflow condition.
