GO7007SB Streaming Media Encoder
The 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
delivers up to full D1 (720x480) resolution streaming
video at 30 fps.
The G07007SB encodes CCIR 601/656 or RGB Bayer
input into MPEG-4/2/1, MJPEG, or H.263 formats.
For irregular HSYNCH video sources, the GO7007SB
delivers A/V synchronization with error resiliency. Optimizing Encoding Performance
The GO7007SB can achieve full resolution with just 4MB
of standard PC100 SDRAM, reducing system costs. It
features an on-chip image processor, SDRAM and USB
controllers, I2C, I2S and parallel (HPI) interfaces.
WISchip's uniquely flexible encoder architecture
accommodates several ISO/ITU video standards. It
provides a glueless interface to industry-standard CMOS
and CCD image sensors via RGB Bayer input. Video Input
