[M4IF Technotes] maximum stream size for single picture for MPEG4 simple profile

[Chen, Kenny]

In H.263 standard, there is a BPPmaxKB, which defines: the number of bits
created by coding any single picture shall not exceed a maximum value
specified by the parameter BPPmaxKb which is measured in units of 1024 bits.
So, there is a maximum stream size limit for a single picture, which will be
a reference for developer for malloc the buffer.
Is there a relative limit in MPEG4 simple profile, or just copy the same
limit from H.263?
In fact, in 14496-4 conformance streams, there is a stream which will use
more bits than the BPPmaxKb that H.263 has defined?
Rgds,
Ken
