本文根据我国电视标准提出了一种质量较高的画中画彩色电视制式。讨论了副图象信号的滤波、存储、取样与量化方式

提出了混合滤波、模数转换器时分复用、取样校正和读出校正等方法。实验结果表明

方案考虑是正确的

主要电路设计是可行的

系统功能是可实现的。

A picture in picture colour television system in accordance with the TV standard of China and with improved quality is put forward. The filtering

storage

sampling and quantization schemes of the subpicture signal are discussed

the methods of composite filtering

time division shared ADC

sampling correction and reading out correction

etc. are proposed. The test results show that the basic consideration of the system is correct

the designs of main circuits are feasible

the system functions are realizable.
