网络实时视频监控系统中流媒体录像服务器的设计与实现
|
摘要
北邮东兴通信科技有限公司开发的网络实时视频监控系统,已实现网络实时监控的效果,满足了用户基本的监控需求。然而,在实际应用中,系统用户对于系统的功能提出了新的需求：录像功能需求。该需求功能已成为此类监控产品的主流功能,具有重要实际应用意义。
本文分析了流媒体录像服务器的功能需求以及服务器整体结构设计,依照功能组件模块化的原则,将流媒体录像服务器设计为三个模块：录像模块、网络接口模块和流化模块。着重介绍了这三个模块的设计与实现。
本文的主要研究成果如下：
1.通过对H.264视频编解码规范以及h264文件格式研究,解决了监控视频录像的本地可播放文件格式保存的问题。
2.通过研究RTP-OVER-TCP技术,采用TCP传输录像流数据RTP数据包,解决了私网内播放终端的录像观看问题。
3.通过研究RTP视频流数据传输中的延时播放技术,解决监控视频录像流式传输RTP格式数据包封装的问题,并设计自定义文件格式以支持RTP格式数据包封装。
The network real-time video monitoring system developed by BUPT Dongxing Communication Technology Co. LTD has reached the target of network real-time video monitoring, and has fulfilled users'basic requirement for monitoring. However, in practice application, system users proposed the requirements to system functions: requirement for video recording. This demand function has become a mainstream feature of such monitoring products, and has important practical meaning.
This paper analyzes the functional requirements of streaming recording server and server's overall structural design. In accordance with the principle of functional components modularity, streaming recording server can be designed as three modules:recording module, network interface module and streaming encapsulation module. Emphatically introduced of the three modules of the design and implementation.
The main results of this paper's studies are as follows:
1.Through the studies of H.264 video codec specification and 264 file format, solve the issue of monitoring video recording's storage in playable file format in server.
2.By studying the RTP-OVER-TCP technology and transport of recording streaming RTP data packets using TCP, solve the problem of terminal in private network viewing of video playback.
3.By studying the delay playing technology in the RTP video streaming data transmission, solve the problem of RTP format packet encapsulation of monitoring video recording streaming. Design a self-define file format to support the RTP format packet encapsulation.
