[Mp4-tech] H.263 header

[Gary Sullivan]

Mayank,
It sounds like you are referring to the start code.
Here is the relevant excerpt text from MPEG-4 Part 2:
short_video_start_marker: This is a 22-bit start marker containing the
value '0000 0000 0000 0000 1000 00'. It
is used to mark the location of a video plane having the short header
format. short_video_start_marker shall be
byte aligned by the insertion of zero to seven zero-valued bits as
necessary to achieve byte alignment prior to
short_video_start_marker. 
Here is the corresponding text from H.263 itself:
5.2.2  Picture Start Code (PSC) (22 bits)
PSC is a word of 22 bits. Its value is 0000 0000 0000 0000 1 00000. All
picture start codes shall be byte aligned. This shall be achieved by
inserting PSTUF bits as necessary before the start code such that the
first bit of the start code is the first (most significant) bit of a
byte.
Best regards,
Gary Sullivan
