Problems solved by technology

In this way, when there are too many input video sources, the user needs to frequently switch the MVR screen to call out the input video source that needs to be previewed, which increases the workload of the operation.
In addition, when the use scene is complex, the user needs to arrange the access sequence of the input video sources reasonably, otherwise it may not be possible to preview all the input video sources being used in one page layout, which increases the difficulty of use

[0046] see figure 1 , the first embodiment of the present invention proposes a multi-screen monitoring method. Such as figure 1 As shown, the multi-screen monitoring method includes, for example, steps S11 to S13.

[0047] Step S11: receiving the area information sent by the video processor;

[0048] Step S12: Perform zooming and splicing processing on the target video source according to the area information to form a spliced ​​picture;

[0049] Step S13: Send the spliced ​​picture to the video processor, so that the video processor adds the spliced ​​picture to the area to be supplemented in the monitoring picture to form a multi-picture monitoring picture and output the multi-picture monitoring picture for display.

[0050] Specifically, the area information mentioned in step S11 includes information such as the screen layout of the area to be supplemented and the screen resolution of the area to be supplemented, for example. The video processor mentioned in step S11 i...

[0064] see Figure 4 , the third embodiment of the present invention provides a multi-screen monitoring method. Such as Figure 4 As shown, the multi-screen monitoring method includes, for example, steps S31 to S35.

[0065] Step S31: receiving the video source interface information sent by the source expander;

[0066] Step S32: according to the video source interface information, a monitoring screen with an area to be supplemented is formed;

[0067] Step S33: Send the area information of the area to be supplemented to the source expander, so that the source expander performs zooming and splicing processing on the target video source according to the area information to form a spliced ​​picture, and send the spliced ​​picture ;

[0068] Step S34: receiving the spliced ​​picture, and adding the spliced ​​picture to the to-be-supplemented area of ​​the monitoring picture to form a multi-picture monitoring picture;

[0069] Step S35: Outputting the multi-screen surveillanc...

Abstract

The invention relates to a multi-screen monitoring method, a multi-screen monitoring device and a multi-screen monitoring system. The method comprises the following steps: receiving area information sent by a video processor; scaling and splicing a target video source according to the region information to form a spliced picture; and sending the spliced picture to the video processor, so that thevideo processor adds the spliced picture to a to-be-supplemented area of a monitoring picture to form a multi-picture monitoring picture and outputs the multi-picture monitoring picture for display. The multi-picture monitoring method provided by the invention avoids excessive input video sources from increasing the user operation amount, and reduces the use difficulty.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a multi-screen monitoring method, a multi-screen monitoring device and a multi-screen monitoring system. Background technique [0002] The MVR (Multi Video Review) function refers to compressing and splicing the input video source of a video processor into a 1080p picture, which is output through the HDMI interface or DVI interface. Users can receive 1080p images through the display, and monitor the status of the input video source in the video processor intuitively and in real time. [0003] With the exponential increase in the application demand for large-screen display, people have put forward more and more refined requirements for video splicing products. For example, the resolution of input video sources is increasing, the number of input video sources is increasing, and new layer processing requirements such as shadows, deduction maps, masks, and special-shaped windows ar...
