Right. One way to think about this is that the Joint Video Team (JVT)
developed a new video codec design (not audio, not file
formats, not transport - only video) and this design simply gets published
across both ISO and ITU letterhead for the sake of
convenience and documentation. Where this new video codec design appears in
the ISO documentation kit it is swept into a chapter in
the MPEG-4 documentation tree (MPEG wasn't about to make a new MPEG-X just for
this new video codec). Where it appears in ITU-land
it is H.264 (following on from H.263 etc). But the codec design is technically
identical and interoperable. There is no other
mandatory binding to anything else MPEG-4, and this new video codec design can
just as easily go over MPEG-2 transport streams, RTP
or anything else that you want.

<Various individuals> seem to have fallen into the same trap as many others by
inappropriately thinking of AVC as MPEG-4. AVC is
nothing more than a new video codec that is PART of the MPEG-4 architecture.
With respect to the MPEG-4 file format, AVC is just
another addition to a table of supported codecs that can be included inside the
file container as part of an MPEG-4 composition.
