伴随着信息化的不断发展,我国电视事业也在蒸蒸日上,通过无线发射的电视节目在传输路径上存在一定的弊端,因为其受到许多外界因素的干扰,对电视节目的质量和频道容量产生很大的影响,CATV邻频系统对无线电视信号的传输研究迫在眉睫。本研究对CATV系统的相关概念进行了简要的分析,讨论了其过去与现状技术的发展情况,并对邻频CATV系统传输无线电视信号的方法进行探讨,争取为我国CATV邻频传输更好的发展提供理论基础和技术支持。
With the continuous development of information technology, the TV business in our country is also booming. There are some drawbacks in the transmission path of TV programs transmitted through wireless networks because they are interfered by many external factors and have a great impact on the quality of television programs and the channel capacity , The research on transmission of wireless television signals by CATV adjacent system is urgent. This paper briefly analyzes the related concepts of CATV system, discusses the development of its past and present technology, and discusses the method of transmitting the wireless television signal in the adjacent CATV system so as to obtain the better CATV adjacent frequency transmission Development provides the theoretical basis and technical support.
