摘要
在远程视频监控系统中,数字视频技术代替模拟视频技术已是大势所趋.而数字视频庞大的数据量一直是困扰多路数字视频传输的根本问题.视频压缩技术能够在保证图像质量的前提下有效地降低数字视频的数码率,从而根本解决多路传输问题.ADV612就是一种专用的视频压缩芯片,在论述了其基本原理后,介绍了其在4路视频光纤传输系统中的应用.
In long-distance video surveillance system, digital video technology is substituting analog video technology. But its large amount of data has been embarrassing the multi-channel transmission. Video compression can reduce the amount of data effectively and ensure the quality of an image,thereby resolving the problem of multi-channel transmission. ADV612 is such a chip used in video compression. Firstly its basic theory was discussed, and then the application to the quadruplex video-fiber-transmission system was .
