【摘要】：视频通信随着网络科技的不断发展以及人们生活、工作的需求,已经从最初的模拟视频通信经过第二代数字视频通信,发展到现在的网络数字视频通信,而且从视频采集、视频编解码以及数据传输等技术都日趋成熟。本论文基于国家第二代信源标准AVS,分别在达芬奇平台和FPGA平台设计实现了物联网视频传感服务器；在Linux平台研究开发设计了软交换中间件系统；在不同平台下设计了客户端软件；形成基于广域网的物联网视频云系统。 AVS物联网视频云系统支持我国自主音视频标准AVS,可实现对视频信号的实时采集、编码压缩、网络存储、广域网传输和解码显示；支持SIP做会话发起协议、RTP/RTSP做网络实时传输和流传输协议,从而将AVS编码器扩展为物联网上的AVS视频传感服务器；开发研制了软交换中间件系统,可在广域网上的M个AVS视频传感服务器和N个客户端之间,实现无阻塞的媒体流软交换,其中,分布式中间件的设计,实现了将M个AVS视频传感服务器现场获取的历史视频数据纪录存储在网络上,满足用户任何地点、任何时间随意观看来自M个AVS视频传感服务器获取的实时视频流和历史视频数据；设计配置了OpenSIPS开源服务器作为整个系统的SIP服务器,协助SIP穿透NAT网关,穿越局域网限制,并且提供代理、注册、认证、计费等功能；设计了Linux平台多画面显示客户端、Windows平台多画面显示客户端以及OMAP3530嵌入式客户端,充分满足了不同需求的用户,形成物联网视频传感服务云系统。该系统可广泛应用于博物馆、大型商场、分布楼宇或交通卡口等场合的视频监控。
[Abstract]:With the continuous development of network technology and the demand of people's life and work, video communication has developed from the initial analog video communication through the second generation of digital video communication to the present network digital video communication, and from the video capture, Video coding and decoding and data transmission technology are increasingly mature. This paper designs and implements the Internet of things video sensor server on the platform of Da Vinci and the platform of FPGA based on the national second generation source standard AVS, and develops the softswitch middleware system on the platform of Linux. The client software is designed on different platforms and the Internet of things video cloud system based on WAN is formed. AVS Internet of things video cloud system supports our own audio and video standard AVS, can achieve real-time video signal acquisition, coding and compression, network storage, WAN transmission and decoding display; The AVS encoder is extended to the AVS video sensor server on the Internet of things by supporting the SIP session initiation protocol and the RTP/RTSP network real-time transmission and streaming protocol. A softswitch middleware system is developed, which can realize non-blocking media stream softswitch between M AVS video sensor servers and N clients in WAN. The record of historical video data obtained by M AVS video sensor server is stored on the network to satisfy any user. Viewing real-time video streams and historical video data from M AVS video sensor servers at any time; Design and configure OpenSIPS open source server as the SIP server of the whole system, assist SIP to penetrate the NAT gateway, traverse the limitation of LAN, and provide proxy, registration, authentication, billing and other functions. The multi-screen display client of Linux platform, the multi-screen display client of Windows platform and the embedded client of OMAP3530 are designed, which fully meet the different needs of users and form the Internet of things video sensing service cloud system. The system can be widely used in video surveillance of museums, shopping malls, distributed buildings or traffic bayonets.
