ALARM RECORDING DEVICE AND A METHOD USING A COLOR BURST SIGNAL IN A TIMELAPSE VCR, ESPECIALLY ENABLING AN OPERATOR TO EASILY IDENTIFY AN ALARMING SECTION BY WATCHING A REPRODUCTION SCREEN

摘要

PURPOSE: An alarm recording device and a method using a color burst signal in a timelapse VCR are provided to alternately record a monitoring video signal where an alarm is generated and an original monitoring video signal, and to display a time when an alarm recording process is started, thereby easily recognizing an alarm recording section by perceiving a color removal voltage change. CONSTITUTION: A multiplexer(104) multiplexes video signals inputted from external cameras, and demultiplexes the multiplexed video signals to video signals of each camera. A combination filter(100) removes a color burst signal from an input monitoring image, and outputs the image. A video switch(102) switches the video signals outputted from the multiplexer(104) and video signals where the color burst signal is removed, and selectively outputs the signals. A video signal processor(103) records the monitoring image video signals of the switch(102) on a recording tape. A timelapse VCR controller(106) alternately inputs the video signals where an alarm is generated and the video signals where the color burst signal is removed, and displays a time when the alarm is generated.
