摘　　要：为降低监测系统视频图像的编码系统复杂度,提出一种视频/图像一体化状态监测技术,采用可分级编码方式压缩编码一次即可同时获得较低分辨率的视频流和高分辨率的图片信息,实际应用中可根据带宽情况或者用户需求从编码的可分级视频流中提取较低分辨率的监控视频码流或抽取相应的高分辨率、高质量的I帧图片进行传输。In order to reduce the complexity of the state detection system, a new video/image integration state detection method is proposed in this paper. The strategy encodes the surveillance video of transmission line by SVC （Scalable Video Coding）, then the low-resolution video stream and high-resolution image could be got at the same time. In the practical applications, it could extract the low-resolution video stream or the corresponding high-resolution image from the video stream to send back to the monitoring center of main station, according the network available bandwidth or users＇ specific demand.
