| 摘 要： | 视频信息存储是网络视频监控的关键技术之一.随着视频存储需求的快速增长,人们也更加关注存储的实时、高效、可靠性.以海思的通用媒体嵌入式处理平台为基础,分析、讨论了在嵌入式Linux2.6内核上设计视频存储系统的基本问题.在不干扰编码视频实时传输的前提下,实现建立在移动存储设备上的编码视频存储方法.特别针对USB存储设备的热插拔特性,利用Unix的proc机制,使得视频存储具备即插即用的能力.

| Abstract: | Video storage is one of core technologies of network video surveillance systems.With the rapid growth of demand for video storage,the real time ability,high efficiency,and reliability of video storage are also more concerned.In this paper,the basic issues on designing video storage system were analyzed and discussed,based on the embedded Linux2.6 kernel and the Uniform Multimedia embedded Application Platform.We present a memory method for encoded video that stored on removable storage devices,under the precondition without interference with the real-time transmission.Especially for the hot plug property of USB storage devices,we used the proc mechanism of UNIX to make the video storage system satisfy a plug and play capacity. |
