Background
A Digital Video Recorder (DVR) is a hard disk Recorder, which is often called a hard disk Recorder and also called a DVR because it uses hard disk Video in comparison with a conventional analog Video Recorder. It is a computer system for storing and processing images and has the functions of long-time video recording, sound recording, remote monitoring and control of images/voice. The DVR adopts a digital recording technology, is far superior to an analog monitoring device in the aspects of image processing, image storage, retrieval, backup, network transmission, remote control and the like, represents the development direction of a television monitoring system, and is a preferred product of the television monitoring system on the market. The touch screen display technology is a novel man-machine interaction input mode, and compared with the traditional keyboard and mouse input mode, the touch screen input is more visual. In order to meet the needs of market customers, multi-touch screen displays have been developed, and in cooperation with recognition software, touch screens can also implement handwriting input. The touch screen is composed of a detection component and a touch screen controller which are arranged in front of a display screen. When a finger or other object touches a touch screen mounted on the front end of the display, the touched position is detected by the touch screen controller and sent to the host computer through an interface (e.g., RS-232 serial port, IIC interface, etc.).
In the correlation technique, the DVR generally looks over the monitoring picture through external VGA or HDMI display, through external mouse, the front panel button, infrared remote control controls the DVR, can be more troublesome and loaded down with trivial details when carrying out some complicated operations, for example drag the progress bar when looking for the video and need click mouse or button many times when enlargeing the video picture to there is certain time delay when using mouse or button, user experience is not good. Although the integrated DVR integrates the display screen and the touch screen on the DVR, the size of the screen is limited by the size of the DVR, if the DVR with a smaller size is provided, the size of the display screen is generally 7 inches to 10 inches, the screen is too small to observe a monitoring picture, the heat dissipation performance of the integrated DVR is poorer, and the integrated DVR can cause the overhigh temperature of the integrated DVR after long-time work, so that the service lives of the display screen and the touch screen are influenced. In addition, the integrated DVR has space limitation, and the requirement that a screen is separated from the DVR when a user uses the integrated DVR is not met.
Therefore, the problems that the digital video recorder does not support an external touch device and the user experience is poor exist in the related technology.
In view of the above problems in the related art, no effective solution has been proposed so far.
