【摘要】：随着网络技术的飞速发展和液晶显示面板的不断普及,生动的影音视频信息以其独特的视觉感染力受到了越来越多的商家与客户的青睐,在商务楼和商场中随处可见各种形形色色的多媒体面板,各种各样的节目为来往的行人提供了大量的信息,而这些信息的载体正是多媒体资源。目前在该行业内,相关从事多媒体播放的公司所制作的播放系统还比较老旧,特别是在多媒体资源的管理上,大部分采用的还是人工插拔SD卡的形式,无法做到便捷地更新多媒体节目。而随着越来越多智能移动终端的出现和计算机网络的普及,使得多媒体自动播放系统和管理系统必须做出革命性的改变。在上一代多媒体资源管理发布系统的基础上,本文对其做了详尽的分析和研究,提出了新的管理发布系统的开发原型。本文对新一代多媒体资源管理发布系统的研究和阐述,主要分为管理端和播放端两块。管理端将针对视频、图片和文字信息,根据用户的权限,进行便捷的管理和使用,还能够直接通过RS232指令管理远程播放终端和发送多媒体节目。播放端重点放在多媒体资源的请求和资源调度上,为了减小传输造成的带宽压力,研究采用P2P分布式的存储方式,达到降低带宽符合的目的。本课题已实现了初步的系统原型,并在实验室环境中进行了测试和调试,对于在真实网络环境的使用,还需进一步的测试。
[Abstract]:With the rapid development of network technology and the popularization of LCD panel, the vivid audio and video information is favored by more and more merchants and customers because of its unique visual appeal. A variety of multimedia panels can be found everywhere in business buildings and shopping malls. Various programs provide a great deal of information for pedestrians, and the carrier of these information is multimedia resources. At present, in this industry, the playback systems produced by the relevant companies engaged in multimedia broadcasting are still relatively old, especially in the management of multimedia resources, most of which are still in the form of manually plugging SD cards. Can not easily update multimedia programs. With the emergence of more and more intelligent mobile terminals and the popularity of computer networks, multimedia automatic playback systems and management systems must make revolutionary changes. On the basis of the previous generation of multimedia resource management and release system, this paper makes a detailed analysis and research on it, and puts forward the development prototype of the new management and release system. In this paper, a new generation of multimedia resource management and release system is studied and described, which is divided into two parts: the management end and the playback terminal. The management side will manage and use the video, picture and text information conveniently according to the user's authority, and can also directly manage the remote broadcast terminal and send multimedia programs through the RS232 instruction. In order to reduce the bandwidth pressure caused by transmission, P2P distributed storage method is adopted to reduce bandwidth compliance. The prototype of the system has been implemented and tested and debugged in the laboratory environment. Further testing is needed for the use of the real network environment.
