Abstract: Techniques are described for handling offsets (gaps or overlaps) that occur between segments of streaming content, e.g., between a segment of primary content (e.g., a live sporting event) and a segment of secondary content (e.g., ad content) dynamically inserted into the stream. The effect of such offsets can be that synchronization between the video and audio portions of the stream can be lost. By tracking a cumulative offset derived from the audio portion of the stream and applying that offset to the presentation times of each affected sample of both the audio and video portions of the stream, synchronization of the audio and video is maintained.
