[Mp4-tech] puzzle about MPEG-4's video profile

[i.g.richardson rgu.ac.uk]

Hello
There are 19 MPEG-4 Visual profiles (last time I counted !) but most manufacturers / developers have gone with Simple Profile and Advanced Simple Profile (coding of rectangular frames). One or two manufacturers made announcements about other profiles (e.g. Dicas, Core Profile) but I notice that Dicas are no longer advertising Core (www.dicas.de). 
AVC is not a profile of MPEG-4 Visual but an alternative coding standard (also part of the MPEG-4 portfolio, published as MPEG-4 Part 10 and also H.264).

	hi..all
	i am puzzling about MPEG-4's video profile.
	From MPEG's home page,we can see MPEG-4 video profile include below:Simple Profile, Simple Scalable Profile,Core Profile,Main Profile,N-bit,Scaleable Texture Profile,Simple Face Profile,Hybrid Profile,Basic Animated Texture Profile. http://www.chiariglione.org/mpeg/faq/mp4-vid/mp4-vid.htm        
	From ISO/IEC JTC1/SC29/WG11 W4457,we can see two MPEG-4 video profile include below:Simple Studio Profile and Core Studio Profile.
	From ISO/IEC JTC1/SC29/WG11MPEG2003/N6231,we only see  Simple Profile,Advance Simple Profile and three AVC Profile.
	I looked for it at some company's web site, and only finded that they support Simple Profile, Advance Simple Profile and AVC.Is it mean that now MPEG-4 only have these Proflie?What the other profiles use?
	Can someone help me?
	thanks!!
