%X A broadcast TV program video surveillance system based on contour detection of station caption is put for- ward.The paper emphasizes the mask capture of opaque station caption,contour detection algorithm and the manage- ment of the system's resource,and at the same time summarizes the basic principles,software structures and the reali- zation.By using multithread programming technology,this system can process video and audio data simultaneously,and can also response to other commands and alarm messages.
