JPEG - Joint Photographic Experts Group - ISO/IEC JTC1/SC2/WG8 
					  CCITT SGVIII
					Status: Draft 5 Jan 1990.
			
	JPEG is a sub-working group of ISO and CCITT. It is in the process
	of developing an international standard for continuous tone (gray-scale
	or colour) still image compression.
 
	DCT based but with DPCM frills etc...
	
	JPEG Chair is Gregory Wallace at DEC. Pennebaker (IBM) ,Mitchell (IBM)
	Ccubed Microsystems (San Jose 408-944-6300) are sampling a chip 
	which they say will be JPEG compatible and will also be capable 
	of doing JPEG type compression on full video at 30 f/s.    

MPEG - Moving Pictures Experts Group. - ISO/IEC JTC1/SC2/WG8 
					Status: Draft March 1990.
	Aim: to develop standards for storage and retrieval of moving
	picture images and sound for digital storage media.

Hope this clears things up ..!

Best regards,
John.
