Abstract: Methods and apparatus are described for encoding and delivering secondary content (e.g., advertisements) for insertion in primary content (e.g., live events, movies, and television shows). Secondary content is encoded such that the duration of any audio component of the secondary content is equal to or longer than the video component duration. When the secondary content is inserted, the overall duration of the inserted content is specified to be equal to the video component duration.

Abstract: Various embodiments of methods, apparatus, systems, and non-transitory computer-readable storage media for buffer recovery in segmented media delivery applications are described. Segments of a live media presentation are stored in a buffer. A number of segments in the buffer is determined to have fallen below a threshold. Based on that determination, various buffer recovery techniques may be performed. In one such technique, a buffered segment is decoded into a first set of video frames, the first set of video frames having a first playback duration. The first set of video frames is encoded into a second set of video frames having a second playback duration that is longer than the first playback duration.
