Dear all,
Can somebody help me with the answers for the following.
1. Which method of Quantization is used in MPEG-4 video simple profile?
Are both methods of Quantizations used in MPEG-4 Video simple profile?
2. Is fixed interval synchronization supported in simple profile? Is it
compulsory to use the method? Is there any mentioning about it in
syntax?(This method requires that VOP start codes and resynchronization
markers appear only at legal fixed interval locations in the bitstream)
Thanks,
Sudhakar K.
