Abstract

A video monitoring system using daisy chain is disclosed. A video monitoring system uses daisy chain, which can display more than four divided screens on one display screen with a simple configuration of the video monitoring system by bypassing video signals captured by a plurality of video cameras through many stages.

Claims

1. An image processing device, comprising:

at least one video input controller for receiving at least one set of digital video data, extracting a synchronous signal from the digital video data, separating the digital video data into luminance component data and chrominance component data, and outputting the synchronous signal and the separated data;

at least one horizontal/vertical scaler for variably downscaling a screen on which to display the video data outputted from the video input controller, in a horizontal and/or a vertical direction according to the number of divided display screens;

at least one input buffer for temporarily storing the screen-downscaled digital video data and then inputting the stored data into a first bypass channel; and

a bypass buffer for collecting first input video data and second input video data, each having a plurality of sets of video data which number as many as the downscaled screens and outputting the collected video data through a second bypass channel.

2. An image processing device, comprising:

at least one video input controller for receiving at least one set of digital video data, extracting a synchronous signal from the digital video data, separating the digital video data into luminance component data and chrominance component data, and outputting the synchronous signal and the separated data;

at least one horizontal/vertical scaler for variably downscaling a screen on which to display the video data outputted from the video input controller, in a horizontal and/or a vertical direction according to the number of divided display screens;

at least one input buffer for temporarily storing the screen-downscaled digital video data and then transferring the stored data into a memory controller;

a bypass buffer for collecting first input video data and second input video data, each having a plurality of sets of video data which number as many as the downscaled screens and transferring the collected video data to the memory controller; and

a memory controller for recording the screen-downscaled digital video data from the input buffer and the digital video data collected from the bypass buffer at respective designated frame memory addresses to configure multi-channel divided screen data, and reading out and displaying the recorded data.

3. The image processing device as set forth in claim 2, further comprising:

an output buffer for temporarily storing the video data of one display screen outputted from the memory controller; and

a video output controller for combining supplementary information with the video data of one display screen outputted from the output buffer and outputting the video data and the supplementary information.
