Two video outputs 150.

Digital video recorders include key functions such as Live, Record, Playback, Backup, Network, and Digital Signage.

Surveillance is a function that displays multiple camera videos and audios on the screen in real time. Playback is a function that retrieves and restores video and audio stored in the storage and displays them on the screen. Digital signage function is output. This function displays the advertisement video specified by the user instead of the monitoring and playback screen.

The input unit 110 receives a surveillance image from at least one camera. The storage unit 120 compresses, processes, and stores the surveillance image received from the input unit 110, and also stores a digital signage image.

In addition, the video output controller 130 receives any image selection information to be output to the display device among the surveillance image, the playback image, and the digital signage image, and displays each display connected to the first and second image output terminals. Video output units 140 and 150 for receiving selection information of a display device to output an image corresponding to the input selection information among the devices, and controlling an image output terminal to which the display device corresponding to the input selection information of the display device is connected. Transmits an image corresponding to the received selection information.

The first video output unit 140 controls the first image output terminal and outputs the image received through the video output control unit 130 to the display device connected through the first image output terminal.

The second video output unit 150 controls the second image output terminal and outputs an image received through the video output control unit to a display device connected through the second image output terminal.

In general, a digital video recorder uses a composite (CVBS) and a VGA output method as main outputs. In the conventional digital video recorder, a video output unit controls both output terminals as shown in FIG. 3. The existing video output method outputs one of the currently operated screens from the monitoring, playback, and digital signage image to the composite and VGA monitor simultaneously. In other words, composite and VGA monitors are the same way that the cloned screen is output. However, this method causes a problem that the same screen is always output to two monitors connected to both output terminals, so that monitoring and playback, monitoring and digital signage image output cannot be output together.

Accordingly, the digital video recorder 100 of the present invention as shown in FIG. 4 constitutes two video output units 140 and 150 so that each of the video output units 140 and 150 has an output terminal (for example, 1 output terminal is a composite terminal, and a second output terminal is a VGA terminal) by separately controlling surveillance video and playback video, surveillance video and digital signage video, etc., to the monitor connected to each output terminal. It has the advantage of being able to perform three main screen output functions (monitoring, playback, digital signage) very effectively using two monitors.

In other words, the output type that can be operated independently is 1. VGA (monitoring) + CVBS (monitoring), 2. VGA (monitoring) + CVBS (playing), 3. VGA (playing) + CVBS (monitoring), 4. VGA (monitoring) ) + CVBS (Digital Signage), 5.VGA (Digital Signage) + CVBS (Surveillance), 6.VGA (Playback) + CVBS (Digital Signage), 7.VGA (Digital Signage) + CVBS (Playback) And the like.

The user selects an image to be output from a surveillance image, a playback image, and a digital signage image, and designates a monitor to output the image. In this case, various methods of displaying the input focus on the output monitor may be set.

For example, pressing and holding a specific button on the digital video recorder 100 or a specific button on the IR remote control for more than a few seconds causes the user's input focus to switch between CVBS and VGA, or when pressing the left and right buttons simultaneously. You can switch between and VGA.

When the user selects any one of the input focus when the input focus is switched between the CVBS and the VGA, the video output controller 130 receives the selection information of the monitor.

Then, the video output controller 130 transmits an image to be output to the video output unit 140 or 150 that controls the terminal (composite or VGA terminal) to which the monitor is connected to be output to the monitor.

In this case, the video output control unit 130 controls the video output terminal to which the display device corresponding to the selection information of the display device which received the surveillance image input to the input unit 110 is connected when the selection information of the surveillance image is input. When the information is transmitted to the video output unit 140 or 150 and the selection information of the playback image is received, the storage unit 120 is searched to restore the compressed and stored surveillance image to the video output unit 140 or 150, and the digital When receiving selection information of a signage image, the storage 120 searches for the digital signage image and transmits the digital signage image to the video output unit 140 or 150.
