【摘要】：广东南方报业新视界传媒有限公司是南方日报控股子公司,于2009年在广州户外LED单点试播取得初步效益,为了进一步扩大市场占有率,增加户外LED屏数量,通过广新信息公司打造的高端IT技术后台支持,将单个LED显示屏组成网络,实现LED多终端多区域联网同步输出以及内容实时更新的效果,打造集商业广告和政府公益广告于一体的LED联播网,由广新信息公司、南方报业集团、广州越秀企业集团有限公司等合作共同建设LED联播网项目,通过强强联合优势互补,达到共赢。本文主要研究视频联播系统的分析、设计和实现。视频联播系统是为实现户外资讯及广告联网实时联播而进行开发的一个多媒体信息联网发布与LED大屏播放管理的平台系统。从应用系统层面看该系统包括:媒体资源管理系统、媒体资源内容发布管理平台、媒体播放策略管理、LED联播集控平台以及媒体播放终端等几大模块。系统提供完善的媒体节目内容的发布及播放控制管理,能根据节目的播放要求进行播表进行自动生成等智能化的播表管理功能,支持插播功能及屏保控制等特殊播放控制和多种多样的播放策略的要求,为LED联播网的安全控制与集中管理工作带来安全性、高效性和便利性,提高播放安全性和工作效率。视频联播系统的广告联播信息可以做到分时,分段,分区联网播放;该系统通过互联网络系统对语音、视频多媒体进行处理,实现远程多点分布式播放、内容实时同步和集中控制;通过在内容制作审核、数据传输和媒体播放环节采取不同的技术手段确保播放内容的完整性、真实性和不可否认性,实现从媒体上传到最终播出的过程安全。平台采用多层次体系结构,保证体系结构的先进性、稳定性和可维护性,同时充分理解用户的需求,并在此基础上对需求进行整合分析,再利用先进的数据建模的方法对系统进行规范设计,保证整个系统的有机完整。文章除了研究视频联播系统的分析设计外,还对目前国内视频联播系统的应用作了简单比较;并对视频联播系统以后在互联网上的应用进行了初步的设想。
[Abstract]:Guangdong Southern newspaper New Vision Media Co., Ltd. is a holding subsidiary of Nanfang Daily. In 2009, it obtained preliminary benefits in Guangzhou Outdoor LED single point trial, in order to further expand its market share. Increase the number of outdoor LED screens, through the high-end IT technology backstage support created by Guangxin Information Company, will form a network of single LED display screen. LED multi-terminal multi-area network synchronous output and content real-time update effect, build a commercial advertising and government public service advertising in one of the LED network, by Guangxin Information Company, Southern newspaper Group. Guangzhou Yuexiu Enterprise Group Co., Ltd. and other cooperation to build a joint LED broadcast network project, through the strong and strong to complement each other to achieve win-win. This paper mainly studies the analysis of video broadcast system. Design and implementation. The video intercast system is a platform system of multimedia information network publishing and LED large screen playback management, which is developed to realize outdoor information and advertising network real time broadcast. From the application system level. The system includes:. Media resource management system. Media resource content release management platform, media play strategy management LED broadcast centralized control platform and media broadcast terminal and other modules. The system provides perfect media program content release and play control management. According to the broadcast requirements of the program, the automatic generation of broadcast table and other intelligent broadcast table management functions can be carried out, supporting special play control, screen saver control and a variety of playing strategy requirements. It can bring security, high efficiency and convenience for the security control and centralized management of LED network. Sub-area network play; The system processes voice and video multimedia through the Internet system, realizes remote multi-point distributed play, real-time synchronization and centralized control of content. Through the content production audit, data transmission and media play link to take different technical means to ensure the integrity, authenticity and non-repudiation of the content. The platform adopts multi-level architecture to ensure the advanced nature, stability and maintainability of the architecture, and fully understand the needs of users. On this basis, the requirements of the integration analysis, and then use advanced data modeling method to standardize the design of the system to ensure the organic integrity of the whole system. In addition to the study of the analysis and design of video broadcast system. The application of domestic video co-broadcasting system is also compared. In addition, the application of video co-broadcasting system in the Internet is preliminarily envisaged.
