为提升广播电视台电视节目的影响力,更好地满足用户对高质量电视节目的收视需求,急需加快广电卫星站电视节目高清、超高清化建设.根据广播电视卫星站的建设现状,提出一种基于四电平脉冲幅度调制(Pulse Amplitude Modulation-4,PAM4)技术的高标清同播系统改造方案.该方案通过扩建和改建标清电视上行通道,最终实现了广电卫星站高清和标清电视节目同传.
Design and Implementation of the Transformation Plan for High Definition Simultaneous Broadcasting System of Radio and Television Satellite Station
In order to enhance the influence of television programs on radio and television stations and better meet the needs of users for high-quality television program viewing, it is urgent to accelerate the construction of high-definition and ultra high definition television programs on radio and television satellite stations. Based on the current construction status of broadcasting and television satellite stations, a high definition co-broadcasting system renovation plan based on Pulse Amplitude Modulation-4 (PAM4) technology is proposed. By expanding and rebuilding the standard definition television uplink channel, the scheme finally realizes the simultaneous interpreting of high-definition and standard definition television programs at the radio and television satellite station.
