1982年,国际无线电咨询委员会(CCIR)在日内瓦召开的第十五次全会上通过了“演播室数字电视的编码参数”的建议,也称601号建议。由于该建议对分量电视三个分量的数码抽样率作了4:2:2的规定,故又将CCIR601建议简称为4:2:2标准。根据这个标准,现行电视的基本结构不作改变,而未来的节目制作及国际间的节目交换则以数字方式进行。 该标准的主要内容是: 1.视频信号进行分量编
In 1982, the International Radio Consultative Committee (CCIR) adopted the Recommendation “Coding Parameters for Television Studio Digital Television,” also referred to as Recommendation 601, at the Fifteenth Plenary Meeting in Geneva.

According to this standard, the basic structure of the existing television is unchanged, and future program production and international program exchange are conducted digitally. The main contents of the standard are: 1. Video signal component code
