Hi all,
I was just evaluating H.26L(ITU-T) video encoding quality. I found, it offers much superior quality at significantly low bit-rate.
It uses Context-based adaptive binary arithmetic coding (CABAC) technique for entropy coding. Among many new things I am just mentioning a few,
it uses more than 1 previous frame for motion estimation, scalable macro-block sizes (16X8, 4X8,  8X16 etc), five different prediction mode
for B -frames encoding, use of deblocking filter for encoder etc.
Is MPEG4 planning to adopt some of this techniques in the newer video profiles like Advanced Real Time Streaming (ARTS) , Advanced Coding Efficiency(ACE)?
regards
Bis
