Problems solved by technology

[0003] For the system display management component, the added virtual resource nodes and real resource nodes are equal, and the system will connect resource nodes and target nodes as needed when displaying. If the connection is unsuccessful, the display will fail, resulting in system function missing
[0004] The inventor found through research on the prior art that virtual resource nodes and virtual target nodes are illegal for real display drivers and display hardware. If there are virtual resource nodes or virtual target nodes in the display path without filtering display driver, will crash the system

Abstract

The embodiment of the invention discloses an image-displaying method and device in a displaying system. In the scheme provided by the embodiment of the invention, a real resource node is used as an object, a virtual target node corresponding to the real resource node is searched, and the virtual target node corresponding to the real resource node is replaced by a real target node to radically avoid the possibility of forming the virtual target node and the real resource node in a displaying path, thereby displaying faults caused by the appearance of the virtual target node in the displaying path are avoided, and system breakdown caused by the appearance of the virtual target node in the displaying path is radically avoided.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an image display method and device in a display system. Background technique [0002] With the release of VISTA and subsequent versions of WIN7, the new display model WDDM has been adopted under WINDOWS, and the traditional windows desktop has also become a D3D program. The use of virtual display devices under XP does not support D3D, which makes the method of using virtual display devices to realize virtual screen becomes unfeasible under the WDDM architecture. The current common method is to add virtual resource nodes and virtual target nodes under the display Adaper instance, use the capability of the graphics card hardware to generate resource data, and then intercept the resource data for remote display. [0003] For the system display management component, the added virtual resource nodes and real resource nodes are equal, and the system will connect resourc...
