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

[Farrugia, Maria, VF-Group]

Hi Gary, and all,
Thank you for responses.
In my second question, I was referring to MPEG-4 Visual decoder.  I am
aware that an MPEG-4 AVC decoder is able to decode H.264 encoded content
as they are the same codec.
Best regards,
Maria

	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?
