【摘要】：近年来,电子、微电子技术发展日新月异,嵌入式设备越来越多的出现在社会生活的各个领域。随着嵌入式设备硬件性能的不断提升、软件技术的不断发展、网络覆盖范围的扩大和建设成本的降低,人们对电子设备的需求已不仅仅局限于文字、图片和声音,网络和视频已经成为现代人生活不可缺少的一部分。因此,具有多功能和高性能的民用消费产品不断涌现出来。目前视频技术已广泛地应用在远程教育、远程医疗、视频会议、在线直播、视频电话和航空航天等多个行业,视频技术已经成为社会发展不可缺少的推动力。嵌入式视频服务器将嵌入式设备与视频技术相结合,可为各应用终端提供实时的视频服务,同时也降低了设备成本,扩大了使用范围。本文致力于嵌入式视频服务器关键技术的研究。阐述了国内及国外视频监控技术的发展现况、发展趋势以及本课题的研究背景及意义。研究了嵌入式系统硬件开发平台、嵌入式Linux开发环境、AAC、MP3和H.264等音视频编码压缩算法和RTSP/RTP/RCP等网络协议。提出了嵌入式视频监控服务器系统的设计方案,并详细介绍了交互协议、音视频信息的采集、视频编码压缩、音视频数据打包、音视频数据发送、定时录像功能和网络客户端音视频播放组件的设计与实现等关键技术。论文的最后一章,针对嵌入式视频监控服务器的研究工作进行了总结,并为后续工作提出了展望和建议。
[Abstract]:In recent years, with the rapid development of electronic and microelectronic technology, embedded devices appear more and more in various fields of social life. With the continuous improvement of hardware performance of embedded devices, the development of software technology. With the expansion of network coverage and the reduction of construction costs, people's demand for electronic devices is not limited to text, pictures and sound, network and video has become an indispensable part of modern life. Currently, video technology has been widely used in distance education, telemedicine, video conferencing, live online. Video technology has become an indispensable driving force for social development in many industries such as video telephony and aerospace. Embedded video server combines embedded devices with video technology. It can provide real-time video service for all application terminals, reduce the cost of equipment and expand the scope of use. This paper is devoted to the research of the key technology of embedded video server, and expounds the current situation of the development of video surveillance technology both at home and abroad. The development trend and the research background and significance of this subject. The embedded system hardware development platform, embedded Linux development environment is studied. MP3 and H.264 audio and video coding compression algorithms and network protocols such as RTSP/RTP/RCP. The design of embedded video surveillance server system is presented, and the interactive protocol is introduced in detail. The key technologies are the acquisition of audio and video information, the compression of video coding, the packaging of audio and video data, the sending of audio and video data, the function of timing video recording and the design and implementation of audio and video playback components of network client. In the last chapter of the paper, the research work of embedded video surveillance server is summarized, and the future work and suggestions are put forward.
