METHOD FOR RECORDING IN CLOSED CIRCUIT TELEVISION

摘要

PURPOSE: A method for recording for a closed circuit television is provided to record the next frame data in case of a normal recording of a frame data while recording a frame data photographed in a television camera to a video tape for improving a reliability. CONSTITUTION: A recording method comprises: transforming an analog signal photographed in a television camera to a digital signal through an analog/digital converter; storing the digitized frame data to a memory for recording to a video tape; rewinding the video tape to the point of the frame start in case of an end of the recording of the frame data for detecting the recording condition of the frame data; recording the next frame data to the video tape in case of a normal recording of the frame data; and rewriting the frame data to the video tape in case of an abnormal recording of the frame data.
