Abstract
A compressed video signal and a compressed audio signal decoding apparatus which including a local access unit counter intended for digital AV applications where access unit headers (e.g. frame headers, audio unit headers or other kind of data unit headers) may be lost or generated by storage media or transmission errors. In order to prevent a resulting AV sync error a value called 'access unit count' is included in each elementary stream. With this value each decoder can detect lost or false access unit headers, and correct the AV synchronization. In order to support editing, an extra bit can be added to indicate discontinuity in the access unit count.
