摘要
目前国内电视台到有线播控中心的信号传输,基本还是采用SDI/ASI光发、光收的模式,通道数目巨大且效率低下。南京广电集团为适应IP化播出,设计建设了全新的有线前端传输平台。平台采用了IP和基带混合编码、使用DCM(数字内容管理器)完成复用,实现了信源传输IP化,链路安全等级高,线路维护简单,可扩展性强。该建设方案具有较好的创新性,有效地增强了集团电视节目的服务功能,在广电业内具备一定的借鉴示范作用。
At present, signal transmission from domestic TV Stations to cable broadcasting control center basically adopts the mode of SDI/ASI optical transmission and optical reception, with a large number of channels and low efficiency. To adapt to IP-based broadcasting, a new cable frontend transmission platform is designed by Nanjing Broadcasting System. This platform adopts IP and baseband mixed coding, and uses DCM(Digital Content Manager) to complete multiplexing, which realizes IP-based source transmission, high link security level, simple line maintenance, and strong scalability. This construction plan has good innovation, and effectively enhances service function of TV programs, which has a certain reference for radio and television industry.
