[M4IF Technotes] h.264 status

[RaghuTS]

Hello,
	I have recently started working on H.264. I have downloaded both
"N-5555.doc" and "JVT-G050.doc". However, I am confused about which document
to follow & which is the latest and most authentic.
There seem to exist many differences in the Syntax tables given in both
documents. For example, sub-clause 7.3.2.1 and sub-clause 7.3.5.3.1 syntax
tables (The 2 tbls which I could immediately make out). Apologies if I have
mis-understood some things. Most of the discussions happening in JVT experts
group, seem to refer "JVT-G050.doc". Pls clarify about the same.
Regards,
Raghu TS

Alf,
You ask a lot of questions.
The draft specification was submitted for final approval as a
standard by the JVT (Joint Video Team) and was promoted to
FDIS (final draft international standard) by MPEG and to
Consent status by ITU-T last month.
In MPEG the standard is in a final Yes/No voting stage.
In ITU-T the standard is in a "last call" stage.
Complete and final approval in both organizations should be
completed within a couple of months.
The MPEG document that is being balloted is N5555.
It is on the MPEG ftp/web site (http://mpeg.nist.gov)
The ITU-T last call document is linked to the AAP last call
page for Study Group 16 on the ITU-T web site (http://www.itu.ch).
The document number of the JVT output document is JVT-G050.
It is on the JVT ftp site (ftp://ftp.imtc-files.org/jvt-experts).
The draft is stable.  Some (relatively minor) problems in it have
been reported to the JVT and will be considered toward creation of
any necessary corrigendum (errata list) at its next meeting.
Similar errata documents have been necessary for many (nearly all)
such standards -- indeed these are often worked on for years after
final approval.
There is reference software.  The reference software coordinator's
site is http://bs.hhi.de/~suehring/tml/.  There is ongoing work to
improve the reference software and it is not in final form (from
what I understand, the decoder is in better shape than the encoder).
Work is also under way toward creation of a conformance test suite
to be finalized within about a year.
Yes, there are some people working on developing products based on
the specification, but it will be a while before truly robust
conforming interoperable implementations are available.
Best Regards,
Gary Sullivan
