时基校正器和后期制作切换器中的分量处理

Component Processing in Time-Base Correctors and Post-Production Switchers

分量记录的出现和以分量形式作某些视频处理所带来的性能改善,使人们产生了对分量制作切换器和时基校正器(TBC)的需要,但目前缺乏分量信号标准以及涉及这类设备的最佳处理格式的有关问题。本文探讨分量处理的某些优点并概述分量处理硬件研制中的某些设计状况。

The advent of component recording, coupled with theimprovements offered by doing certain types of Video processing in componenform, has created the need for component production switchers and time-ba-se correctors (TBCs). The lack of standards for component signals raisesquestions as to the best processing format for such eguipment. This arti-ele explores some of the advantages of component processing and outlinescertain design aspects used in the development of component processinghard ware.
