摘要
如何建立远程网络视频连接、实现NAT穿透并进行高效的视频流编解码是视频监控系统的研究难点,基于SIP协议建立的网络视频监控系统采用高压缩比的MEPG4视频编码格式,支持IP视频多路并发,利用软交换平台对视频流进行集中管理,实现了网络视频连接建立,视频流编解码、加密、传输,以及智能报警、录像、抓拍、回放等功能。
How to set up a remote network video connections, NAT penetration, efficient video stream encoding and decoding is the research in the field of video monitoring.MEPG4 video encoding formats, which is of high compression ratio, is used in the SIP-based network video monitoring system.The system supports multi-channel IP video, using soft-switching platform for centralized management of the video stream to achieve the establishment of a network video connection, video streaming encoding and decoding, encryption, transmission, and intelligent alarm, video capture, playback and other functions.
