基于MJPEG的DVR设备手机监控算法

The cellphone supervise the DVR Based on MJPEG

本文介绍了改进后的MJPEG编码用于数字硬盘刻录机(DVR)的手机监控。其中jpeg压缩算法由硬件实现。改进后的MJPEG算法良好的支持了QCIF(176x144)大小的视频,通过TCP协议向网络发送,适用于带宽较低的网络连接。用于大面积监控时,使用GPRS网络,网络状态良好可达到每秒3-5桢。该算法为手机远程监控提供了良好的解决方案。

The paper give a modified Mjpeg encoding, the DVR can be supervised by cellphone. The jpeg Compression Algorithm was implemented on a fpeg. The modified Algorithm support qCif video .Using tcp Protocol transfer video. It suporrt low band net. When using larger scale, GPRS net,in good conduction then five frame per second. This Algorithm is a good method using cellphone supervise the dvr through internet.
