[M4IF Technotes] Timing code in mpeg4 bitstream

[Christoph Lampert]

Hi,
I'm getting crazy over this stuff, but maybe you can give me
a quick answer: 
Consider a stream of GOP  IBBPBBPBBP... which have a length of up to 
200 frames until the next I-frame. 
vop_fixed_time is set and for simplicity let's assume that it's 
plain 25fps, so vop_time_increment_resolution is 25 and 
fixed_vop_time_increment is 1. 
How am I supposed to set the time flags in the frames?
Is  modulo_time_base  supposed to go from 0 to 7 1-bits (=200/25) 
while vop_time_increment varies from 0 to 24 ? 
So frames are simply numbered by their time/position? 
Or is there something else to consider?
