Abstract
The basic principle of present network video system and video compression methods is analyzed.The present charge coupled device(CCD) image formation principle and the color reversion technology and methods is introduced emphatically.The differences of compressing the color image and the gray image by JPEG compression algorithm is elaborated.Finally a new network video compression scheme based CCD primary data is proposed.Comparing with the usual compression scheme by simulating
