Product Background:
CompCore Multimedia, Inc., the leader in low cost, high performance
MPEG solutions, is proud to announce the availability of the SoftPEG tm
MPEG decoder. SoftPEG is the highest performance MPEG software decoding
solution in the industry. Using the same patented algorithms as
CompCore's efficient hardware solutions, SoftPEG tm is able to generate
unparalleled picture and sound quality with full audio/ video
synchronization, without added hardware or assemble language
programming.

Performance:
	Achieves real-time performance at SIF resolution (352 x 240 @
	30 frames/sec or 352 x 288 @ 25 frames/sec) on 90 MHz Pentium
	systems with YUV color space conversion hardware assist.
	Delivers smooth motion quality and full audio/video
	synchronization on base level Pentium and   486DX2 systems.
	Decodes video frames faster than real-time on basic PowerPC,
	MIPS and Alpha systems.  

Features:
	Fully decodes and displays any MPEG-1 compliant bit stream.
	Uses CompCore's patented algorithms to efficiently decode,
	synchronize and present audio/video  frames. Able to perform
	decode and presentation without full utilization of CPU.
	SoftPEG tm delivers exceptional audio/video synchronization
	quality regardless of platform (Pentium,    486, MIPS,
	PowerPC).  Automatically configurable to either DCI or WinG
	interfaces.  SoftPEG, tm designed with a 16 bit interface in
	mind, runs under the Window 3.1, as well as Windows     NT,
	without the use of Win32S.  Compliant to OpenMPEG standard.
	Written in high level C code making the design easily portable
	to other platforms.
