Abstract: Methods and apparatus are described for efficiently representing manifests and playlists for media presentations. Some media streaming protocols include repetition syntax by which a sequence of media segments having the same duration can be represented with a single entry. A pattern syntax is introduced by which repeating patterns of segment durations in a cycle may be represented in manifests and playlists.

Abstract: Methods and apparatus are described for making broadcast content available as an on-demand asset soon after all of the video fragments of the broadcast content have been made available. As the video fragments of the broadcast content are made available, they are requested and archived. When all of the fragments for the duration of the broadcast content are available (e.g., a live event ends), a VOD-style manifest is generated and the archived fragments are made available for downloading or streaming using the VOD-style manifest.

Abstract: Method and apparatus for detecting a pattern used by an encoder when outputting segments for HTTP streaming. A pattern detector receives, as part of a HTTP streaming protocol, a sequence of video segments and a sequence of audio segments forming at least a portion of a media presentation. The pattern detector identifies a duration of the video segments and then sums the durations of the sequence of audio segments until the summed duration is an integer multiple of the duration of the video segments. The pattern detector determines the number of the audio segments used to form the summed duration which includes the number of audio segments forming a cycle of the pattern. This pattern is then added to a manifest of the media presentation along with a repeat indicator defining the number of times the pattern is repeated.
