【摘要】：现代社会中，多媒体信息无处不在，这里的信息媒体涵盖文字、照片、图片、声音、动画和视频等等。近年来，，多媒体在广告宣传领域的应用，加大了广告信息传播的渗透性，得到了人们的青睐。然而，旧的多媒体内容管理系统，对多媒体内容以及终端设备缺乏有效的组织管理，因此企业不得不花费大量的人力财力物力在播放内容管理以及终端设备的管理维护上，严重影响了企业的经济效益和社会效益。本文在深入分析当前媒体播放系统存在问题的基础上，开展了分布式媒体播放系统的研发工作。该系统的建设主要包括两个部分：1）播放客户端管理，主要实现媒体终端的组织、运营管理与维护、以及接收用户定制信息并将其展示到终端设备（数字标牌、LED显示屏等）；2）多媒体内容管理，主要实现播放信息的采集、审查以及分发，为媒体播放客户端提供内容素材。其中，针对播放客户端管理部分，由于媒体终端数量多、覆盖面广而导致媒体终端组织、运营管理及维护低效、困难等问题，本文提出基于树形覆盖网的终端组织模型。该模型将基于树型的覆盖网作为基本拓扑结构，并将整个媒体播放系统划分为若干安全域，有效的解决分布式媒体终端的组织和管理问题；基于该组织模型，本文给出了媒体播放客户端的设计和具体实现。针对多媒体内容管理部分，根据业务需求和系统功能需求，本文给出了多媒体内容管理系统的数据库设计方案、系统架构设计与实现。最后对本系统的设计和开发进行了总结，并对不足之处提出了一些看法和思考。
[Abstract]:In modern society, multimedia information is everywhere, including text, photo, picture, sound, animation and video. In recent years, the application of multimedia in the field of advertising has increased the penetration of advertising information, and has been favored by people. However, the old multimedia content management system lacks effective organization and management of multimedia content and terminal equipment. Therefore, enterprises have to spend a lot of human, financial and material resources on the management of broadcast content and the management and maintenance of terminal equipment. Seriously affected the economic and social benefits of enterprises. On the basis of deeply analyzing the problems existing in the current media playback system, this paper develops the research and development of the distributed media playback system. The construction of the system mainly includes two parts: 1) broadcast client side management, mainly realizes the organization, operation management and maintenance of the media terminal. And receive the customized information and display it to the terminal equipment (digital signboard LED display screen etc.) multimedia content management, mainly realize the collection, review and distribution of playing information, and provide content material for the media playback client. Aiming at the problems of media terminal organization, operation management and maintenance inefficiency and difficulty due to the large number of media terminals and wide coverage, this paper proposes a terminal organization model based on tree overlay network. The model takes the tree-based overlay network as the basic topology and divides the whole media playback system into several security domains to effectively solve the problem of organization and management of distributed media terminals. This paper gives the design and implementation of the media player client. In view of the multimedia content management part, according to the business requirement and the system function demand, this paper gives the database design scheme, the system architecture design and the realization of the multimedia content management system. Finally, the design and development of the system are summarized, and some views and thoughts are put forward.
