视频编码电路主要实现接收8位CCIR656格式的YUV数据，（例如MPEG解码数据），并编码成亮度Y和色度信号C，以及合成CVBS信号，经过D/A转换后输出。基本的编码功能包括副载波产生，色差信号调制，同步信号内插。 主要应用在视频处理，军事图像处理。 GM7221设计原理图-Video encoding circuit main reception 8 CCIR656 format YUV data (such as MPEG decoding the data), and encod

The Video Processing Subsystem is a collection of video processing IP subcores, bundled together in hardware and software, abstracting the video processing pipe. It provides the end-user with an out of the box ready to use video processing core,
