[Mp4-tech] H.264 and MPEG-4 Video codecs compatibility

[Gary Sullivan]

The answer to your first question is somewhat a product decision
question as much as it is anything else.  Many products that can decode
"H.264" (a.k.a. MPEG-4 AVC a.k.a. 14496-10) can also decode MPEG-4
Visual Simple Profile bitstreams.  However, that is at the discretion of
the product designer or the system designer.  There are no requirements
for such functionality in those video coding standards themselves.
In your second sentence, when you refer to "an MPEG-4 decoder", are you
referring to an MPEG-4 AVC decoder or an MPEG-4 Visual decoder?
Best Regards,
Gary Sullivan

	Dear all,
	Could someone please let me know if H.264 can decode video
content encoded with MPEG-4 Visual simple Profile?  
	And also if an MPEG-4 decoder can decode content encoded with
H.264?
	Thanks in advance,
