随着媒体传播方式的转变,广播电视中心正向融媒体转型,节目制作和发布越来越依赖互联网流媒体信号.传统广播信号调度系统已无法满足网际互连协议(Internet Protocol,IP)化制播的需求.基于此,设计基于软件定义网络(Software Defined Network,SDN)的广播IP音频信号调度系统,分析其优势、架构及未来发展方向.
Design of Broadcasting IP Audio Signal Scheduling System Based on SDN
With the transformation of media communication mode, the radio and television center is transforming into a convergent media center, and program production and release increasingly rely on Internet streaming media signals. The traditional broadcasting signal scheduling system can no longer meet the requirements of Internet Protocol (IP) based broadcasting. Based on this, a broadcasting IP audio signal scheduling system based on Software Defined Network (SDN) was designed, and its advantages, architecture, and future development direction were analyzed.
