摘要：

针对视频监控的嵌入式实际应用,提出了一个基于QT的无线多路视频监控终端软件解决方案。采用QT跨平台开发库设计用户界面及其应用程序,无线传输采用802.11g协议,采用基于MPEG-4的视频编码方案XVID对视频图像信号编码解码,使用RTP/RTCP协议保证流媒体的传输,设计嵌入式Linux进程和线程,保证多路监控的效率和质量,实现一个由软件完成编码解码的无线多路视频监控系统。实验结果验证了方案的可行性,并有较好的监控效果。

关键词: 多路监控, 嵌入式Linux, QT, MPEG-4, RTP协议

Abstract:

For the application of video monitor in embedded system,we propose a solution for wireless multi-video monitor terminal software based on QT.We use QT,a cross-platform lib to design user interface and applications.For wireless transmission,we use 802.11g protocol,for encode and decode of video signal,we use XVID,a MPEG-4 based video coding solution,we also use RTP/RTCP protocol to ensure transmission of stream media.We design embedded linux processes and threads to ensure efficiency and quantity of multi-monitor.Finally,we realize a multi-video monitor system using software to complete encode and decode.Experimental results indicate that this solution is feasible and has well monitor effect.

Key words: multi-channel monitoring, embedded Linux, QT, MPEG-4, RTP protocol
