Combined windowing and outputting method and device for multipath signals

Abstract

The invention discloses a combined windowing and outputting method and a device for multipath signals, and the method comprises the following steps: grouping the received multipath signals based on a preset grouping mode; respectively performing multipicture segmentation simulation on each display area corresponding to each grouping based on the received segmentation mode; and respectively combining each signal output to each display area of each grouping after multipicture segmentation simulation into an output signal at one path, and outputting the output signal to a window corresponding tothe display area for displaying. In the scheme of the invention, the multipath signals can be displayed once with no need of opening a corresponding window for each signal source; once windowing operation can enable the multipath signals to be displayed on one window, thus greatly lowering the operations of opening and closing windows, and saving the windowing time for a large screen; and grouping management of the multiple signals can be realized by opening a few of windows, thus reducing time and resources for carrying out output management on the multipath signals.

Description

technical field [0001] The invention relates to the technical field of display output, in particular to a multi-channel signal combination windowing output method and device. Background technique [0002] In the current field of display output technology, especially the VW (ultra-high resolution digital display video wall system) industry, it is usually necessary to output and display a group of signal sources, and when outputting and displaying a group of signal sources, it is usually one by one To perform windowing operation on these signal sources, one signal source corresponds to one window. However, in many current application fields, such as the monitoring field, there is a need to display multiple output signals on one display wall. In this case, windows are opened for the multiple signals one by one. It is acceptable when the number of windows is small, but in the case of a large number of signal sources, such as in the field of video surveillance, the number of sig...

However, in many current application fields, such as the monitoring field, there is a need to display multiple output signals on one display wall. In this case, windows are opened for the multiple signals one by one. It is acceptable when the number of windows is small, but in the case of a large number of signal sources, such as in the field of video surveillance, the number of signal sources usually has dozens, hundreds or even more numbers, one by one Opening so many windows requires a lot of system resources, and it takes a lot of time and resources to maintain these windows, and because there are a lot of signal sources, if too many windows are opened at one time, it is not conducive to signal monitoring
