摘　　要：针对传统视频监控系统存在视频流畅性较低、监控数据传输成功率低、误码率高等问题,提出基于数字媒体DSP的远程网络视频监控系统。系统硬件设计中,上位机采用LabVIEW编程实现,用于控制摄像支撑设备转动、镜头参数调整以及视频数据播放与远程显示控制等功能;下位机使用数字媒体DSP为核心处理器,建立含有视频数据采集输入、传输以及摄像支撑设备控制等模块。系统软件设计中,详细介绍了远程网络视频监控系统中视频图像运动目标检测算法。实验结果表明,所提系统能有效实现流畅清晰的视频远程网络传输,视频数据传输成功率可达到98.467%,误码率最低为0.006 35%,能够满足实际远程网络视频监控的需要。A remote network video monitoring system based on digital media DSP is proposed to solve the problem of low video fluency,low success rate of monitoring data transmission and high bit error rate in the traditional video monitoring system.In the hardware design of the system,the upper computer is programmed with Lab⁃VIEW,which is used to control the rotation of camera support equipment,lens parameter adjustment,video data playback,remote display control and other functions.The digital media DSP is used in the lower computer as the core processor to build the modules including video data acquisition input,transmission and camera support device control.In the system software design,the detection algorithm of the video image moving target in the remote network video monitoring system is introduced in detail.The experimental results show that the proposed system can effectively realize smooth and clear video remote network transmission,whose success rate of video data transmission can reach 98.467%,and minimum bit error rate is 0.00635%,which can meet the needs of actual remote network video monitoring.
