Device and method for implementing video matrix output display and video matrix equipment

Abstract

The invention discloses a device and a method for implementing output display of video matrix and a video matrix apparatus. The method facilitates operation of the video matrix apparatus, and reduces misoperation rate. The device comprises a television wall initializing module for receiving at least one display unit addition instruction, adding a plurality of display units in a television wall previewing region of a display screen according to a size of a single display unit in the addition instruction, and determining video channel numbers corresponding to the added display units; a mapping relationship establishing module for establishing a mapping relationship between the video channel numbers corresponding to the display units and physical output port identifiers of the video matrix aimed at each display unit; and a video source output module for determining corresponding physical output port identifiers according to the video channel numbers in the received video signal output instruction, and performing output display of video signals output by a selected video source through the corresponding physical output port.

Description

technical field [0001] The present invention relates to the technical field of video monitoring, in particular to a video matrix output display realization device, method and video matrix equipment. Background technique [0002] Video matrix equipment refers to an electronic device that outputs m-channel video signals to n-channel monitoring equipment arbitrarily through the method of array switching. Generally, the input of the video matrix is ​​greater than the output, that is, m>n. Specifically, such as figure 1 As shown, it is a schematic structural diagram of the video surveillance system. The front-end video signal acquisition device outputs the collected video signal to the video matrix device, and the video matrix device outputs the received video signal to the TV wall for display as a video image. Since the input of the video matrix is ​​greater than the output, it is necessary to switch the video source through the video matrix device during specific operations...

AI Technical Summary

Problems solved by technology

Since the number of video sources connected to the video matrix equipment is very large, that is, the number of input video signals is huge, in the prior art, digital identification is used to record video sources and display output channels, and the video output can be selected by configuring the digital symbols of input and output channels by the user It shows that the digital video matrix equipment of digital technology also retains this switching method. Since the current video matrix equipment does not realize visual operation locally, it is necessary to realize the selection of video source and output display through the matrix controller, so as to give users and maintenance personnel It brings great inconvenience to the operation of the video matrix, which may easily lead to misoperation and abnormal configuration
