摘要
网际互连协议(Internet Protocol,IP)化技术凭借高带宽和灵活性等优势,为广播电视传输系统带来了新的可能,特别是在广播电视基带架构层,IP化音频(Audio over IP,AoIP)技术可以发挥重要作用,完成从源信号采集到发射的全过程音视频传输任务。基于此,介绍AoIP的相关概念、标准和应用优势,阐述基带架构的组成层次、采集编码和自动化功能,分析其技术特点。在此基础上,详细探讨AoIP技术在基带系统各层面的应用情况,包括AoIP网络部署、音视频流处理、自动化实现和同步方案等,并说明不同应用的效果。
With the advantages of high bandwidth and flexibility,Internet Protocol(IP)technology has brought new possibilities for broadcast and television transmission systems,especially in the baseband architecture layer of broadcast and television,Audio over IP(AoIP)technology can play an important role,complete the whoel process of audio and video transmission from source signal aqcuisition to transmission.Based on this,this paper introduces the relevant concepts,standards and application advantages of AoIP,expounds the composition level of baseband architecture,acquisition codinga nd automation functions,and analyzes its technical charactersitics.On this basis,the application of AoIP technology in baseband sysetm is discussed in detail,including AoIP network deployment,uadio and video stream processing,automation realization and synchronization scheme,and the effect of different applications is explani ed.
