随着科技技术的发展,电视总控监看系统也由传统的只是对电视信号进行切换、分路、转制和传送,很难对信号做深层次的处理,演变到现在的数字电视综合监看,在不降低电视画面可视质量的前提下,不仅大大压缩每一路电视节目占用的带宽,还可以在有限的播出通道带宽中播出更多频道的数字电视节目。本文就将对电视总控监看系统的发展过程进行阐述。
With the development of science and technology, the television master control monitoring system is also traditionally switched, shunted, converted and transmitted from the television signal, making it difficult to do deep-seated processing on the signal and evolve into the current digital television comprehensive monitoring , Not only reduces the visual quality of the TV picture, but also greatly reduces the bandwidth consumed by each television program and can broadcast more channels of digital television programs in the limited broadcast channel bandwidth. This article will elaborate on the development of the television master control monitoring system.
