aThe WISchip GO7007SB is designed for devices, such as
DVRs, PVRs, or STBs, and for streaming IP solutions over
Ethernet, such as video conferencing or surveillance. It
.Ddelivers up to full D1 (720x480) resolution streaming
video at 30 fps.
wThe G07007SB encodes CCIR 601/656 or RGB Bayer
input into MPEG-4/2/1, MJPEG, or H.263 formats.
wFor irregular HSYNCH video sources, the GO7007SB
w omdelivers A/V synchronization with error resiliency.
U.cOptimizing Encoding Performance
et4The GO7007SB can achieve full resolution with just 4MB
eof standard PC100 SDRAM, reducing system costs. It
hfeatures an on-chip image processor, SDRAM and USB
Scontrollers, I²C, I²S and parallel (HPI) interfaces.
ataWISchip's uniquely flexible encoder architecture
.Daccommodates several ISO/ITU video standards. It
wprovides a glueless interface to industry-standard CMOS
wwand CCD image sensors via RGB Bayer input.
