Abstract

The invention provides a screen-span window display method and a screen-span window display device. The screen-span window display method comprises the following steps: determining lengths and widths of target sub blocks according to lengths and widths of screens forming a television wall; equally dividing the screens according to the lengths and the widths of the target sub blocks, and recording corresponding relationships of equally divided sub blocks and screens to which the sub blocks belong; when a screen-span window needs to be displayed in the television wall, determining sub blocks covered with the screen-span window according to the position of the screen-span window in the television wall; according to the sub blocks covered with the screen-span window and the recorded corresponding relationships of the sub blocks and the screens to which the sub blocks belong, determining target screens covered with the screen-span window, and determining the positions of the screen-span window in the target screens; and according to the positions of the screen-span window in the target screens, displaying the screen-span window in the television wall. Through application of the embodiment, the applicability of the display scheme of the screen-span window can be improved.

Description

technical field [0001] The invention relates to the technical field of video surveillance, in particular to a method and device for displaying windows across screens. Background technique [0002] With the rapid growth of social informatization, the demand for information visualization has also expanded rapidly, and at the same time, it is becoming more and more difficult to realize high-end visualization. The information displayed by a single display device is far from meeting the market demand, especially in some important places such as monitoring centers, command centers, and dispatch centers. Therefore, the multi-screen splicing system has become an indispensable core basic system for information visualization. [0003] At present, in the multi-screen splicing system, it is required that the large screens or displays (hereafter take the large screen as an example) to be spliced ​​into a whole (TV wall) must be the same size, and the schematic diagram can be as follows ...
