本文详细介绍了安徽广播对外传输系统的设计与应用。本文介绍的码流传输和基带传输的选择,主备传输系统的设计,“一键直通”应急功能的实现,在广播中心播控机房的搭建及传输方面具有一定的推广和借鉴意义。通过E1码流传输的双向性实现对传输环节广播信号的链路监测,更是今后网络技术在播控领域发展的方向。
This paper introduces the design and application of Anhui Radio External Transmission System. This article describes the choice of code stream transmission and baseband transmission, the design of the primary and backup transmission system, the realization of the emergency function of “one key direct connection”. It has certain promotion and reference significance in the construction and transmission of broadcasting control room. The bidirectional transmission of the E1 code enables the link monitoring of the broadcast signal in the transmission link, which is also the direction for the development of the network technology in the field of broadcast and control in the future.
