Problems solved by technology

To operate the Graphical User Interface GUI (Graphical User Interface), you must configure a mouse for operation. In engineering, the mouse is generally placed in the cabinet. If there are many NVRs, there are many mice, which is easy to confuse. Affected by the length of the mouse cable, the operation is inconvenient

Embodiment Construction

[0029] In order to describe the technical content, achieved goals and effects of the present invention in detail, the following descriptions will be made in conjunction with the embodiments and accompanying drawings.

[0030] The most critical idea of ​​the present invention is: the scheme adopts the remote mouse event sent by the remote terminal 2 and receives the local mouse event, and creates a virtual input device to simulate the mouse, resolves the local mouse event or the remote mouse event into target data, and reads The data can also be displayed by the mouse, and the real-time data stream can be uploaded to the remote terminal 2 by responding to the request of the remote terminal 2, so that the remote mouse can simultaneously control multiple network hard disk video recorders, reduce costs and realize centralized control of the front-end display output.

[0031] Please refer to figure 1 , a kind of NVR remote control screen method of the present invention, comprises t...

Abstract

The invention discloses a network video recorder (NVR) remote screen control method, screen control device and screen control system. The method includes the following steps that: S01, receiving a remote mouse event transmitted by a remote terminal and a local mouse event; S02, creating a virtual input device simulation mouse, parsing the local mouse event or the remote mouse event into target data, and injecting the target data to a core to drive the simulation mouse; S03, reading YUV data responding to the mouse events in the core and displaying the simulation mouse; S04, encoding the displayed YUV data to form a real-time data stream; and S05, responding to a request of the remote terminal and uploading the real-time data stream to the remote terminal. According to the network video recorder (NVR) remote screen control method, screen control device and screen control system of the invention, a plurality of network video recorders can be controlled remotely through the mouse, and therefore, and configuration cost can be reduced, and centralized control on front end display output can be realized.

Description

technical field [0001] The invention relates to screen control technology in video surveillance, in particular to an NVR remote screen control method, control device and control system. Background technique [0002] At present, the video surveillance system implements decentralized control and centralized management, and the centralized management of the front-end NVR reflects the current media stream and parameter configuration, but for the remote network video recorder NVR (Network Video Recorder,) local GUI (Graphical User Interface) output Centralized management has not yet been implemented. NVR (Network Video Recorder) displays output on the screen through HDMI (High Definition Multimedia Interface) and VGA (Video Graphics Array). To operate the Graphical User Interface GUI (Graphical User Interface), you must configure a mouse for operation. In engineering, the mouse is generally placed in the cabinet. If there are many NVRs, there are many mice, which is easy to conf...
