Problems solved by technology

[0003] However, although this improves the window opening efficiency, due to the large number of signal sources opened at the same time, and the size of the large digital display splicing wall is very large, if there is an abnormality in the window of a certain signal source, the user may not be able to find it in time, which will affect the display. The effect, especially for the demonstration site on important occasions, the display effect is poor and the user experience is poor

Abstract

The invention provides a windowing abnormity handling method and a windowing abnormity handling system for a combination of multiple channels of signals. The windowing abnormity handling method comprises the following steps of acquiring a window image corresponding to a signal source in the combination of the multiple channels of signals when windowing of the combination of the multiple channels of signals is finished; analyzing similarity between the window image and a pre-stored blue screen image to obtain a similarity value; inquiring whether signals exist in a signal channel corresponding to the signal source or not if the similarity value is greater than a preset similarity threshold value; determining that windowing of the signal source is abnormal if the signals do not exist in the signal channel corresponding to the signal source; and outputting a signal source windowing abnormity reminding message to a control PC (personal computer). By the windowing abnormity handling method and the windowing abnormity handling system for the combination of the multiple channels of signals, a user can find out window abnormity problems conveniently in time, and a displaying effect is improved.

Description

technical field [0001] The present invention relates to the technical field of splicing display, in particular to a method and system for abnormal processing of multi-channel signal combination and window opening. Background technique [0002] Existing large-scale control rooms usually use ultra-high-resolution digital display splicing walls as display screens. Due to the large number of connected signals, especially for demonstration sites on important occasions, signal sources are usually pre-combined for quick demonstration. Realize the operation of multiple signal sources opening windows at the same time. [0003] However, although this improves the window opening efficiency, due to the large number of signal sources opened at the same time, and the size of the large digital display splicing wall is very large, if there is an abnormality in the window of a certain signal source, the user may not be able to find it in time, which will affect the display. The effect, esp...
