摘要
目前,大型直播节目外场与电视播总控机房之间的信号、数据传输主要以卫星和光纤传输为主,以网络传输为辅,各传输载体相互分离,成本高昂,模式单一。本文探讨利用IP技术实现多种媒体数据实时、多向互通传输的可能性,并通过“all in one”视频服务器完成最简播出应急方案,以降低传输成本,提升信息沟通效率,增强播出安全性。
At present, the signal and the data transmission between the large-scale live program scene and the TV broadcast master control room is mainly based on satellite and optical fiber, supplemented by the network. These transmission media are separated from each other, which of the costs are high, and the modes are single. This paper discusses the possibility of using IP technology to realize real-time multi-directional intercommunication transmission of various media data. This mode completes the simplest broadcast emergency plan through the “all in one” video server, which reduces transmission costs, improves information communication efficiency,and enhances broadcast security.
