备份系统在集群演播室的应用

Application of backup system in cluster studio

对广播电视台直播系统来说系统的可靠性以及传输的灵活性实时性都是非常重要的。介绍了一整套音频备份系统,系统支持多种备份和替换模式,即使在极端故障模式下也可以保证直播不受影响。为此在系统中采用了Dante音频传输网路,在传输协议完全支持AoIP网络。该网络的工作模式下系统完全支持单播和组播的音频网络混合使用,为系统配线的灵活性提供了强大的支持。Dante网络的传输延时以及音频质量可以满足广播电视台的要求。简要介绍了AES/EBU的传输接口。

It is very important to Radio and television broadcast systemthat is Reliability, flexibility and real-time transmission. In this article, we introduce a complete set of audio backup system. The system supports a variety of backup and replace mode, even in the extreme failure mode can also ensure that the live broadcast is not affected. For this reason, the Dante audio transmission network is adopted in the system, and the transmission protocol fully supports the AolP network. In lhe network mode, the system supports unicast and muhicast audio network, which provides strong support for the flexibility of the system. Dante network transmission delay and audio quality can meet the requirements of radio and television stations. In this article, the author briefly introduces the AES/EBU transmission interface
