异构视频监控系统媒体资源共享与发现机制研究

Research on Media Resource Sharing and Discovery Mechanism of Heterogeneous Video Surveillance System

本文主要探讨了异构互连视频监控系统中视频媒体的共享与定位问题。根据视频媒体传输时大容量、时间长、高速度等特点,提出了一种多级的监控视频媒体共享与定位方法,该方法从媒体资源的描述、媒体资源的发布、媒体资源的定位三个方面进行研究,主要解决视频监控系统中视频文件和视频流的共享与定位问题,利用P2P相关技术设计原理,制定了通用的监控媒体资源描述规范和多级监控媒体资源搜索算法,以满足多级互连视频监控网中视频资源快速高效的定位需求。

In this paper,we discuss the problem of sharing and locating of video media in heterogeneous inter-connected video surveillance system.According to the video transmission characteristics such as large capacity,long duration and high speed,this paper proposes a multi-level media sharing and locating method for video surveil-lance.This method mainly solves the problem of sharing and locating of video files and video stream.Based on the P2P related technologies,we define a general monitoring media resource description specification and a multi-level moni-toring media resource search algorithm to meet the requirements of fast and efficient video resources discovery in in-terconnected video surveillance systems.
