Abstract
A method and apparatus for determining timing information from an MPEG-2 stream carrying Advanced Video Coding (AVC) content is disclosed. The method includes receiving an initial access unit from the MPEG-2 stream, and determining whether the MPEG-2 stream contains a temporal picture order count (POC) parameter. If the temporal POC parameter is contained in the MPEG-2 stream, the temporal POC parameter is used to compute a presentation time stamp (pts) for a next presentation unit (m).
