Embodiment Construction

[0015] The specific implementation of the video window control method and system of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0016] refer to figure 1 , figure 1 Shown is a flow chart of the video window control method of an embodiment, including the following steps:

[0017] S10, acquiring the bottom desktop video signal of each display unit of the multi-screen display device, and synchronously reading the cursor position information, cursor shape information and cursor action information of each display unit;

[0018] The above-mentioned cursor position information can include information such as which video window the cursor in each display unit is on, and which position is located in the corresponding video window; The coordinate system of each window is obtained, as well as the coordinates (x, y) of the cursor. The cursor position information is the coordinates (x, y) of the cursor. During the transmission o...

Abstract

The present invention relates to a video window control method and system. The above video window control method includes the following steps: acquiring and synchronizing the underlying desktop video signal, cursor position information, cursor shape information and Cursor action information; regenerate a cursor graphic moving on the top layer of the output video signal according to the cursor position information and cursor shape information; superimpose the cursor action information on the cursor graphic to obtain a control cursor, and use the control cursor Control the bottom-level desktop video signal and the upper-level acquisition video signal; it can realize the operation of the upper-level acquisition video signal through the cursor corresponding to the bottom-level desktop video signal, which improves the convenience of operation and improves the control efficiency of the video window.

Description

technical field [0001] The invention relates to the technical field of software control, in particular to a video window control method and system. Background technique [0002] Generally, the video window displayed by each display unit on the multi-screen display device needs to be controlled through a corresponding cursor. Usually, the video window above is formed by superimposing the bottom-level desktop video signal and the upper-level collected video signal, but the cursor is generally generated on the bottom-level desktop, so it can only move above the bottom-level desktop video signal, and cannot operate other upper-level collected video For the relevant content in the signal, the video window corresponding to the video signal collected by the upper layer can only be moved, enlarged and other operations by transmitting instructions in other ways, which affects the control efficiency of the above video window. Contents of the invention [0003] Based on this, it is ...
