【摘要】：人类社会正在逐步的走进信息化社会,计算机应用和发展已经深入到社会的各行各业,经营和管理的网络化,数字化已经成为一项衡量企业的综合实力的标志。同时通过网络投放广告已然成为企业和商家宣传自己的主要手段,但是目前许多公共场所采用的都是单机广告机,其内容的更新都需要人为的去操作,因此它的更新周期比较长,且人工维护费用昂贵,而少部分场所采用的是流媒体技术,即通过网络在线实时的播放,其播放效果往往受到网络连接状况的影响,所以一套广告内容更新快,人工参与的环节较少,播放效果好的系统成为众多商家,企业单位进行广告宣传的新的手段。因此在这样的背景下,通过采用网络技术,实现远程操控广告更新和播放控制是很有前景的。鉴于以上需求,本文结合网络型多媒体播放系统的服务器软件的分析和设计展开论述。首先分析了单机广告机播放、流媒体机播放以及下载到本地后播放这三种方式的特点,最终采用了下载媒体文件到本地后播放的技术方案。本系统由多媒体播放终端设备、网络以及服务器组成,服务器程序设计是系统研发的关键环节。采用visual studio2010为前台开发工具,后台主要应用了sql sever2005数据库,实现服务器与前台终端的通信、设置终端设备的工作参数、读取工作状态、更新媒体播放列表、下发多媒体文件等功能,其中服务器与前台的通信主要通过套接字进行信息的交互,而下发媒体文件时实现了多线程断点续传功能。服务器程序还要求能够操纵数据库以保存、修改、查询多媒体播放终端的相关数据。
[Abstract]:Human society is gradually stepping into the information society, computer application and development has penetrated into all kinds of industries, management and management of the network, Digitization has become a symbol to measure the comprehensive strength of enterprises. At the same time, advertising through the Internet has become the main means for enterprises and businesses to promote themselves, but at present, many public places use single-machine advertising machines. The update of its content needs artificial operation, so it has a long updating period, and the cost of manual maintenance is expensive, while a few places adopt streaming media technology, that is, online real-time broadcast through the network. Its play effect is often affected by the network connection condition, so a set of advertisement content updates quickly, the manual participation link is relatively small, the play effect good system becomes many merchants, Therefore, under this background, it is very promising to use network technology to realize remote control of advertisement update and play control. In view of the above requirements, this paper discusses the analysis and design of the server software of the network multimedia playback system. The system is composed of multimedia playback terminal equipment, network and server. Server program design is the key link of system development. Visual studio2010 is used as the foreground development tool. The background mainly uses sql sever2005 database, realizes the communication between server and foreground terminal, sets the working parameters of the terminal equipment, reads the working status, updates the media playlist, sends the multimedia files, etc. The communication between the server and the foreground is mainly carried out by means of socket, and the multi-thread breakpoint continuation function is realized when sending the media file. The server program also requires that the database can be manipulated to save and modify. Query multimedia playback terminal related data.
