摘要
随着广播电视数字化的进展,广播电视安全播出和数字业务多样性的双重需求对广电传输网络提出了更高的要求。浙江广电传输网的设计方案基于动态同步传输模式技术,支持广电业务及传统传输等多业务接口,结合数字微波及光缆传输两种传输路径,既保证安全播出又能适应新媒体快速发展需求,介绍了相关技术方案,并对方案涉及的功能验证、指标测试进行研究。
The digitalization of broadcast is highly demanding for broadcast transmission network in terms of safety broadcasting and multiple digital services.The transmitting network of Zhejiang Broadcasting is designed on the basis of Dynamic Synchronous Transfer Mode.With the application of microwave digital transmission as well as cable transmission,this multiservice network can promise safe broadcasting and it is geared to the need of rapid development of new media.This paper introduced this network and the technology it concerns,and studied the functional verification and target testing.
