Synchronization arrangement for a compressed video signal

摘要

Apparatus for providing a compressed video signal comprising: a source (50) of compressed video signal; counter circuitry (52) for generating a time stamp; a processor (53) for   forming auxiliary information including first and second data fields provisionally containing said time stamp and a further time stamp, respectfully;   providing first and second flags indicating the presence or absence of said time stamp and said further time stamp in said first and second data fields, respectively; and   forming packets respectively including headers and payloads, wherein said headers identify at least in part the contents of said packets and ones of said payloads include a segment of compressed video signal and ones of said payloads include said auxiliary information.
