随着彩色电视技术的发展,世界各国对彩色电视分量信号传输技术进行了大量研究和应用,相继出现了时分多路编码器“Timeplex”和MAC传输技术等。彩色电视分量信号的传输替代了复合信号,使传送信号的质量能够有相当大的提高,主要原因是:1)色度信号变成比较低的频率 With the development of color television technology, many countries in the world have done a lot of research and application on the color television component signal transmission technology, and have appeared the “Timeplex” and the MAC transmission technology of time-division multiplex encoder. The transmission of color television component signals replaces the composite signals, enabling a considerable improvement in the quality of the transmitted signals, mainly due to: 1) the chroma signal becomes a lower frequency
