摘要： 传统的远程视频监控系统所需软硬件资源大、视频传输协议和视频采集设备控制协议相互独立,系统传输带宽要求高、时延长、实时性不高。为解决这些问题,利用开放无线监控协议中的信息体结构,将视频信息传输、视频采集设备控制和其他信息融合在一个数据包中,并基于iOS 移动操作系统和H. 264 视频编码标准,设计并实现一种集视频传输与控制于一体的移动视频监控软件。测试结果表明,该移动视频监控软件可有效提高移动视频监控系统的性能,具有控制响应速度快、传输带宽要求低、分辨率自适应以及实时视频播放流畅等特点。

Abstract: For large software and hardware resources required of traditional remote video surveillance system, independence between video transmission protocol and video capture device control protocol, high bandwidth
requirements,large delay,and real-time differential,this paper uses Open Wireless Surveillance Protocol(OWSP) specific information structure,puts the video data transmission,device control,and other information in a packet,and based on the iOS mobile operating system and H. 264 video standard,designs and implements a set of video transmission and control in one of the mobile video monitoring software. Test results show that this monitoring software effectively improves the performance of mobile video surveillance system with fast control response, low transmission bandwidth, adaptive resolution,and real-time video play smooth.
