摘要
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.
Abstract
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.
