MPEG reviewed the results of its open video compression viewing tests, and
concluded that there is evidence for advances in video coding technology
that warrant the start of a new video coding project.  MPEG is discussing
with ITU-T Study Group 16 the formation of a Joint Video Team (JVT) to carry
out this new project. For MPEG, this project will result in a new part of
the MPEG-4 Standard, which is scheduled for completion in spring 2003. 
'Having seen significant technological advances, we have decided to extend
MPEG-4 with state-of-the art technology. In this way, we continue to serve
the evolving needs of the industry', said Dr. Leonardo Chiariglione,
Convener (chairman) of MPEG, on the decision to add a new part to MPEG-4.
'MPEG-4 Version 1 was finalized in 1998, and is adopted by a growing number
of companies and consortia. Incorporating new technology in MPEG-4 means
that industry can protect its investments in MPEG-4 while using improved
technology'. 
Dr. Gary Sullivan, rapporteur for video coding work in ITU-T SG16 and
chairman of MPEG's Video Group said, 'We are working toward creating a new
joint standardization project to extend the frontiers of video compression.
It's exciting to think what this world-class team of ITU-T and MPEG coding
experts could achieve.'

Subject: [M4IF Technotes] H.26L video coding
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
