DIVISIONAL SCREEN OUTPUT DEVICE FOR A CCTV SYSTEM

摘要

PURPOSE: A device for divisional screen output of a CCTV system is provided to output a screen which is divided into nine areas at the output part of the video by encoding each video signal corresponding to each channel and storing each video signal corresponding to each channel at the memory part using the decoder. CONSTITUTION: The device for a CCTV system comprises a switching part(11) which switches the video signal of the eight channels that is output from the video input part sequentially; a nine channel switching part(20) which switches the video signal of the ninth channel that is output from the video input part; a channel compound part(12) which outputs the video signal at the decoder part as a result of compounding the video signals switched at each of the switching part; and a memory control part which controls the recording and the output of the video signal.
