Patent ID: 7369157

Claim:
A video monitoring system for configuring and displaying a multiplexed image consisting of a plurality of pictures each corresponding to a video signal captured by each of video cameras, comprising: A/D (Analog/Digital) converters, each of which converts a channel video signal outputted from the corresponding video camera into digital video data and outputs the digital video data through a video source channel; one or more slave video signal processors coupled in a daisy chain manner, each of which scales down digital video data of individual channels outputted through the video source channels from each of the A/D converters, outputs the scaled-down digital video data to a first bypass channel of the slave video signal processor, re-collects digital video data outputted through a first bypass channel of a preceding slave video signal processor and collected digital video data outputted through a second bypass channel of the preceding slave video signal processor, and outputs the re-collected data to a second bypass channel of the slave video signal processor; a master video signal processor that scales down the digital video data of individual channels outputted through a video source channel from the A/D converters, records on a frame memory the scaled-down digital video data and digital video data outputted from first and second bypass channels of a previous slave video signal processor, and configures and outputs video data corresponding to a multiplexed image; and a D/A (Digital/Analog) converter for converting the video data corresponding to the multiplexed image into an analog video signal and outputting the analog video signal to a video display device.
