Embodiment Construction

[0013] A video mosaic multi-window data distribution method, the method comprising:

[0014] Establish a three-dimensional coordinate system on the splicing screen, and read the video data corresponding to the windows of each display unit;

[0015] According to the physical position of each display unit window in the three-dimensional coordinate system, calculate and record the coordinates of the three-dimensional coordinate system at the edge of each display unit window;

[0016] The video distribution system calculates the superimposed part of each display unit according to the received window edge coordinates of each display unit;

[0017] The video distribution system distributes the video data of each display unit after superimposing part of the video data of each display unit according to the calculation.

[0018] The present invention establishes a three-dimensional coordinate system on the splicing screen, reads and calculates the boundary coordinates of each display ...

Abstract

The invention discloses a video splicing multi-window data distribution method. The method comprises steps that a three-dimensional coordinate system is established on a splicing screen, and video data corresponding to each display unit window is read; according to the physical position of each display unit window in the three-dimensional coordinate system, a coordinate of each display unit window edge in the three-dimensional coordinate system is calculated and recorded; an overlapped portion of each display unit is calculated by a video distribution system according to the received each display unit window edge coordinate; each display unit video data is distributed by the video distribution system according to the overlapped video data of each display unit. The method is advantaged in that the three-dimensional coordinate system is established on the splicing screen, the boundary coordinate of each display unit is read and calculated, the video data is distributed through the video distribution system, video playing is carried out through each display unit, taking out the data of each display unit from the memory is not needed, and data bulk of reading from the memory is saved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of video image processing, and in particular, to a video mosaic multi-window data distribution method. Background technique [0002] Video splicing processor is a device that can display multiple video signal sources on multiple splicing screens arbitrarily. Therefore, each splicing screen often needs to open multiple different windows, and the size and position of the windows can roam and overlap arbitrarily. [0003] Since the splicing screen has a fixed size, when multiple windows are opened, the windows often overlap. At this time, only the content of one of the windows can be displayed, and the part of the blocked window cannot be displayed. However, this part of the data is not actually needed. Contents of the invention [0004] The main purpose of the embodiments of the present invention is to provide a video mosaic multi-window data distribution method, which at least partly...
