一、引言彩色电视信号的数字编码和传输,近几年来许多国家进行了大量的研究工作。欧美、日等发达国家在实验室的研究阶段接近完成,而我国当前正处于发展初期。有关演播室内电视信号数字编码的国际标准文作了详细介绍和阐述。本文拟就在PCM三次群(34·368Mb/s)上传输数字彩色电视信号的可行性进行若干理论上探讨和计算。结果表明:根据当前图象信
I. INTRODUCTION The digital coding and transmission of color television signals have carried out a great deal of research work in many countries in recent years. The developed countries in Europe, the United States, Japan and other developed countries are almost completed in the research stage of the laboratory, and our country is currently in the early stage of development. The international standards for the digital coding of television signals in the studio are described in detail. This article intends to discuss and calculate the feasibility of transmitting digital color television signals over the PCM third-order group (34.368 Mb / s). The result shows: According to the current image letter
