广播电视有线无线融合网中的e MBMS技术及在山东广电的应用

eMBMS Technology in Cable and Wireless Converged Network and Its Application in Shandong Cable TV Network

在移动网络迅猛发展趋势下,视频业务的需求逐渐增大,传统的广播不能覆盖移动和手持终端的视频业务需求。在广播电视有线无线融合网中应用eMBMS技术可以最大程度地覆盖广电用户,不但能够实现无线广播和传输资源的共享,也将提高网络资源的利用率。首先介绍了eMBMS的研究背景及广电的需求,然后对eMBMS技术进行了分析,从技术架构到关键节点为融合网的多播技术进行解释,同时介绍了eMBMS在山东的应用。

As the mobile network develops rapidly,video business demands are gradually increasing,and traditional broadcast cannot cover the demand for video services of mobile and handheld terminals. The application of eMBMS technology in the cable and wireless converged network can cover broadcasting users to the maximum extent,share wireless and transmission resources,and improve the utilization rate of network resources. This paper first introduces the research background of eMBMS and the demand of radio and television,analyzes the eMBMS technology,explains the multicast technology of the converged network from the technical architecture to the key nodes,and then introduces the application of eMBMS in Shandong province.
