[Mp4-tech] Clarifications regarding H.263

[Shailendra Singh]

Hi,
  Could someone please clarify:
(1) Is there an appropriate forum where one can get clarifications
regarding H.263 related issues ?
(2) Is there an existing conformance document for H.263 ? I found one
at http://ftp3.itu.ch/av-arch/video-site/h263/h263con1.doc but it
seems to be outdated and if I search on ITU's site, I can see the
H.263 recommendation, and various Annexes and Appendixes, but no
document which explains how to  test a H.263 decoder for compliance
with the recommendation, the way it is explained, for example in
14496-4.
Regards,
Shailendra
