The Design And Implementation Of Vedio Simultaneous Broadcast System

Guangdong Nanfang New Vision Media Co.,Ltd, the holding subsidiary of Nanfang Daily,has made initial achievement in the test broadcasts of Guangzhou outdoor LED in 2009. To further extend market share and increase the amount of outdoor LED display, we will connect every single LED display into a network to realize the effects of multi-terminal and multi-zone cyber-sync-output and real-time update through high-end technical background support by Guangxin Information Industry Co.,Ltd as well as create a LED broadcast network with commercial and public service advertising. The LED broadcast network program is jointly constructed by Guangxin Information Industry Co.,Ltd, Nanfang Daily Group and Yuexiu Group through combination of assets and mutual advantages to make win-win.This paper will mainly focus on analysis, design and the use of the system. Video broadcasting system is a platform system with multimedia network information publishing and LED Display Management to realize the real-time cyber-broadcasting of advertisements and outdoor news.There are media resource management system, management platform on inofrmation issues of media resource, strategy management on media player, LED broadcasting integrated control platform and media player terminal in the system from the view of application system.The system provides the public with perfect meida programme content, play control management and intellgent management function in automatic generation as required.It also supports inter-cut function and other play control function like screensaver as well as diverse demands in broadcasting strategy to bring security, high efficiency and convenience in security control and centralized management of LED broadcasting network.The information of advertisement broadcasting in the system could be broadcasted in every period of time or zone.The system has realized remote multipoint distibuted playing, real time synchronization of content and centralized control through the processing of voice and multi-media video by Internet system. It also has realized the process secruity from uploading on m edia to broadcasting through different technological means like check in content production, data transmission and media player to ensure the integrity, authenticity and non-repudiation of the content.The platform adapts multi-level system to ensure advancement, stability and maintainability of the structure. Meanwhile, it also makes integrated analysis on the basis of full sense of customer demands and normative design to the system with advanced methods of data modeling to ensure organic integrity of the system.This paper also simply describes the differences of two domestic ad applications and some thoughts about the ad applications in the internet.
