网络广告机设计与实现
发布时间：2018-07-29 11:43
【摘要】： 随着我国经济的快速发展,广告已经是商家、企事业部门宣传自己的主要手段,利用广告机来发布广告已逐渐被人们普遍认同和接受。但是目前大多数公共场所均采用的是单机广告机,其内容的周期更新比较长且更新过程需要较高人工费用,而少数场所虽然采用流媒体技术,即通过网络在线实时播放,但其播放效果常常受网络不良状况困扰,所以实现一种广告内容更新便捷、人工参与环节少、播放效果好的广告机成为众多商家,企事业单位进行广告宣传新的重要选择。因此在这种背景下,通过采用高效播放器和网络技术,实现远程广告内容更新和控制播放是有意义的。 基于以上需求,本文结合网络广告机设计与分析工作展开论述。首先分析了单机播放、流媒体播放和下载本地后播放各自技术特点,最终采用下载媒体文件到广告机后本地播放的技术方案。然后结合硬件平台,对ARM-Linux嵌入式操作系统进行了分析和移植。接下来介绍了网络广告机媒体播放器Mplayer解码流程、逻辑结构、音视频同步技术、代码结构和配置编译等。最后介绍了SSH协议并将其应用到实际的应用软件中。项目开发经过前期的选题、市场调研、技术分析等阶段,现在已经进入试验阶段且运行测试效果良好。
[Abstract]:With the rapid development of our country's economy, advertising has been the main means for businesses, enterprises and institutions to publicize their own, the use of advertising machine to publish advertising has been gradually recognized and accepted by people. However, at present, most public places are using single-machine advertising machines, whose contents are updated for a long period and require high labor costs. Although a few places use streaming media technology, that is, real-time broadcast online through the network, But its play effect is often troubled by the bad condition of the network, so it is convenient to realize a kind of advertisement content renewal, the artificial participation link is few, the play effect good advertisement machine has become many merchants, the enterprises and institutions carry on the advertisement propaganda the new important choice. In this context, it is meaningful to use efficient player and network technology to realize remote advertising content update and control play. Based on the above requirements, this paper discusses the design and analysis of network advertising machine. Firstly, the technical characteristics of single player, streaming media play and local playback are analyzed. Finally, the technical scheme of downloading media files to local player is adopted. Then combined with the hardware platform, the ARM-Linux embedded operating system is analyzed and transplanted. Then it introduces the Mplayer decoding flow, logic structure, audio and video synchronization technology, code structure and configuration compilation. Finally, the SSH protocol is introduced and applied to the practical application software. The development of the project has entered the experimental stage and the effect of running the test is good after the early selection of topics, market research, technical analysis and so on.
