[M4IF Technotes] video packet length

[ramakrishna_kakarala agilent.com]

Hi,
How is video packet length signalled to the
decoder? I don't see a field for it in the 
video bitstream syntax.  I know the *maximum* length 
is specified (if data partitioning is used)
but I don't know how the actual value is
signalled.  Is it signalled in the systems
layer?
If the packet length is not signalled,
then how does fixed interval synchronization
work? 
thanks for your help
Ram
