摘要
随着数字技术在传媒领域的广泛应用,构建高效的数字化制播系统成为推进传媒业改革发展的重要环节。以五莲县融媒体中心为例,探讨数字化制播系统建设中的总体框架设计、功能模块规划、网络架构方案及关键技术,分析视频服务器、编码技术、信号交换技术等数字制播关键技术,在此基础上提出数字制播系统总体采用的台网分离、采编播出分离等框架,设计采编子系统、播出子系统和监控子系统三大模块,提出分层设计的网络架构方案。
With the widespread application of digital technology in the media field,building an efficient digital broadcasting system has become an important part of promoting the reform and development of the media industry.Taking the converged media center as an example,this paper explores the overall framework design,functional module planning,network architecture scheme and key technologies of the digital broadcasting system construction.It first analyzes the key technologies of digital broadcasting such as video server,encoding technology and signal exchange technology.On this basis,it proposes the overall framework of separation of network and station,separation of editing and broadcasting adopted by the digital broadcasting system,and designs the three major modules of editing subsystem,broadcasting subsystem and monitoring subsystem.It also proposes a hierarchical network architecture scheme.
