A multi-window display and switching method and device

Abstract

The invention discloses a multi-window display and switching method and device, and relates to graphics system drawing, display and operation control technology. The method includes: the graphics engine determines the window attribute value of the multiple business application windows according to The superimposed display order of multiple windows on the screen; when the end user needs to switch the target window to the topmost layer of the screen, the graphics engine replaces the window of the target window with the preset window attribute value for displaying the window at the topmost layer of the screen Attribute value; after the window attribute value is adjusted, reorder the windows so that the target window is displayed at the top of the screen. The present invention can set the display order according to the user's expectation, and enables the user to dynamically switch and activate the surviving windows in the system through the remote controller.

Description

Technical field [0001] The invention relates to drawing, display and operation control of a graphics system, in particular to a remote control-based multi-window display and switching method and related devices. Background technique [0002] In the field of graphics, the multi-windows of the graphics system all adopt a unified display priority, and the display that is started after the display is displayed on it. It is normal for the input peripherals of the desktop with a mouse or touch screen and other touch devices. The windows are displayed in order, and the windows are displayed in order. There will be no difficulty in switching. However, in embedded devices such as digital TV set-top boxes, the multi-window approach basically adopts the idea of ​​parent-child window, that is, first create a window called the main window, and then derive and manage the child windows based on the window. This strategy can only Meet traditional applications. [0003] With the increasing divers...

However, on embedded devices such as digital TV set-top boxes, the multi-window method basically adopts the idea of ​​parent-child windows, that is, first creates a window called the main window, and then derives and manages child windows based on this window. Such a strategy can only Meet traditional applications

[0003] As the value-added services of embedded devices such as set-top boxes and industrial control systems become more and more diversified, the needs of users are also diversified. Some business windows that start later are not expected to be displayed on the top, and the strategic performance bottleneck of the parent-child window cannot be solved. Affecting user experience, multi-process and multi-window graphics system applications similar to desktops have emerged as the times require, but how to set the display order according to user expectations and how to switch between these windows is very difficult
