Abstract

The embodiment of the present invention discloses an input signal segmentation method and device based on the output of the mosaic wall. After judging that there is an intersection between the output signal of the window and the display screen, the embodiment of the present invention divides the initial coordinates, height and width of the input signal and numbering, modifying the divided input signal according to the parity of the initial coordinates of the numbered input signal, so as to reasonably and effectively support the division of the input signal whose width or height is an even number.

Description

technical field [0001] The invention relates to the field of video wall output, in particular to an input signal segmentation method and device based on video wall output. Background technique [0002] The large-screen video wall is generally composed of several rows and columns of display screens, and multiple signal windows can be opened in the large screen. The signal of the large-screen video wall signal window is the acquisition signal of the processor's acquisition card, which is controlled by the main control to the corresponding output card for processing and then output, so the output signal has a linear relationship with the input signal. Each signal window may span multiple display screens. At this time, when processing, the input signal needs to be divided according to the linear relationship, so that the output signal of the display screen spanning each window has a corresponding input signal. When the width or height of the input signal that needs to be segmen...
