Dave I'm copying you on it for its potential as an I-P submission.


For the latter to make sense it's probably useful for me to add a little
context on what MPEG4 is (and why it's not called MPEG3).


In the original MPEG days the idea was that MPEG 1 would be CD/T1 data rates
(~150 KB/sec); MPEG2 would be the NTSC/PAL/SECAM replacement; MPEG3 would be
HDTV (higher data rates than MPEG2); and MPEG4 would be "low" bit rates
(lower than MPEG1).


What ended up happening was (a) MPEG2 scales to very high bit rates, and (b)
the digital HDTV race began to move on its own very fast track separate from
ISO (thanks to the FCC largely).  As a result the MPEG3 group was scrubbed,
but the name MPEG4 already meant "low data rate" to some people so the group
was not renumbered.


My friends in the MPEG world project that the time overlap of MPEG4 relative
to MPEG2 will be kind of like the overlap of MPEG2 relative to MPEG1, i.e.,
MPEG4 will start now, even though there are still some clean-up things to be
done on MPEG2.
