高清新闻直播系统设计与应用

Design and Application of High Definition News Live Broadcast System

新闻直播系统,是一种位置相对集中,具有高清化、智能化、规模化的全媒体交互式演播室集群,多个演播室能够共同制作同一节目。该系统可通过资源共享,让系统之间无缝融合,既能独立工作,又能有机整合,为大型电视节目制作提供了创新性的技术手段。目前,新闻直播系统逐渐呈现高清化的特点。为改善新闻直播的效果,各电视台纷纷开展了对高清新闻直播系统的设计与研究。基于此,从蒙城县广播电视台的高清新闻直播系统设计方案入手,分析融媒体直播车系统整体设计理念,分别从视频系统、音频系统、同步系统及其他关联性业务系统入手,探讨直播集成系统的设计架构,并在此基础上,分析系统的应用拓展模式,开展演播室布局的优化设计。

News live broadcasting system is a relatively centralized,high-definition,intelligent,large-scale all-media interactive studio cluster,multiple studios can jointly produce the same rpogram.The system allows seamless integration between systemst hrough resource sharing.It is able to work independently and integraet organically,providing innovative technical means for the production of large-scale television programs.At present,the news live broadcast system is gradually showing the characteristics of high definition.In order to improve the effect of news live broadcast,variousT V stations have carried out the design and research of high definition news live broadcast system.In this context,this paper startsw ith the design scheme of the high definition news live broadcsat system of Mengcheng radio and television station,analyzes the overal ldesign concept of the convergent media live broadcast truck ssytem,discusses the design architecture of the live broadcast integrated system from the video system,audio system,synchronization system and other related business systems,and on this basis,analyzes the application and expansion mode of the system.
