[M4IF Technotes] CABAC - AVC (h264) question

[kasturi rangam]

Hi,
	I have a question on CABAC decode for macroblock type
	in I slice.
	I have the following revision of the spec:
	JVT-D157, generated:2002-08-10
	Table 9-20 on page 93 has the binarization for macroblock
	types for I slices.
	From the table it looks like by decoding the macroblock type,
	we get the Imode, nc (chroma cbp) and AC flag.
	There are 2 issues.
	1. In table 9-23, the binarization type specified for ctx_mb_type_I
           is Table 9-14, which i think should be table 9-20
	2. There is additional ctx_cbp_chroma (context from chroma cbp).
           From what I understand, this applies only for P and B slices,
	   since the mb_type for I slices already has chroma cbp.
	Please let me know if my assumptions are right.
Thanks,
Kasturi
