Digital video recorder connected to a plurality of display screens

Abstract

The invention relates a digital video recorder which is connected with a plurality of displayers; the video recorder is at least connected with a first displayer and a second displayer; the digital video recorder which can display an image data with an image graphic joint VGA format through a picture of the first displayer is provided with a converter which can convert the image data with a serial digital image outputting SDVO format into the image data with the image graphic joint VGA format; and the image data with the image graphic joint VGA format which is converted by the converter is displayed through the second displayer. By combining the converter which can convert the image data with the serial digital image outputting SDVO format into the image data with the image graphic joint with a PCle Express x16 form in a plurality of grooves of the digital video recorder to use, the invention allows that a digital video recorder can be connected with a plurality of displayers, which can allow the user to more effectively search and determine the desired video-graphed images.

Description

technical field [0001] The present invention relates to a digital video recorder connected with multiple displays. In particular, it refers to a digital video recorder connected to multiple monitors in order to receive images captured by a surveillance camera and store them on a hard disk or display them on multiple monitors. Background technique [0002] Generally, a digital video recorder (DVR: Digital Video Recorder) 21 connected to a plurality of monitoring cameras, such as figure 1 Shown, be connected to monitor 20, keyboard (22), mouse (23) etc., and on above-mentioned digital video recorder 21DVR, from a plurality of surveillance cameras, for example from 16 surveillance cameras 10 1 ~10 16 The received images are recorded on a large-capacity recording medium such as a hard disk (HDD). [0003] And, through the above-mentioned 16 monitoring cameras 10 1 ~10 16 The images respectively received are represented by the above-mentioned display 20, for example, as fi...
