摘要
随着我国科学技术的迅猛发展,电子通信技术得到了前所未有的进步,电子科技逐渐融入人们的生活。在先进科学技术的推动下,广播电视技术也得到了长足的发展,产业革新的脚步越来越快。但是,就目前的广播电视行业来看,还存在比较多的人工值守操作方式,自动化程度不高。在当前的经济发展背景下,广播电视必须朝着小功率、多布点、单频同步覆盖的方向发展,广播电视设施的信号源系统由单一向多路备份,由单一模式向多元化模式转化。本文以广播电视的信号源系统作为切入点,结合实践经验,着重分析广电发射设施信号系统的传输及自动切换相关技术要点,希望能推动广播电视行业的产业进步。
With the rapid development of science and technology in China, electronic communication technology has made unprecedented progress, and electronic technology has gradually integrated into people＇s lives. Promoted by ad- vanced science and technology, radio and television technology has also made considerable progress, and the pace of industrial innovation is faster and faster. But as far as the current radio and television industry is concerned, there are still more manual on-duty operation mode, the degree of automation is not very high, and there is a broader technical application space. Under the background of today＇s economic development, broadcasting and television must develop toward the direction of low power, multi-point distribution, single-frequency synchronous coverage. The signal source system of broadcasting and television facilities from a single to multi-channel backup, from a single mode to a diversified mode. In this paper, radio and television signal source system as a starting point, the author focused on the analysis of radio and television transmission facilities signal system transmission and automatic switching related technical points, hoping to promote the radio and television industry progress.
