Problems solved by technology

However, this method has a long delay and incomplete data, mainly due to the low efficiency of Android reading the framebuffer content of the driver. When the refresh rate is relatively fast, such as the game screen, only half of the system desktop may be intercepted due to the refresh problem. The upper and lower sides of the picture or desktop image data do not match. In addition, this method does not have the resolution adjustment function, and it is only able to obtain the system display image data.
[0006] In these technical solutions, the remote desktop server basically obtains the image data rendered by the system indirectly, and cannot directly participate in the system image rendering and display process, and it is not applicable in the remote desktop image redirection scenario based on the Android system. The main reason is The resolution control function is not implemented for the Android system; obtaining system image data indirectly will cause a large display delay and cause a very poor user experience

Abstract

The invention discloses a remote desktop image redirection system based on an Android system with controllable resolution. The system includes: an Android system server and a remote desktop client, wherein the Android system server includes: an Audio Finger on the system framework layer Process, the image hardware abstraction layer module of the hardware abstraction layer and the remote desktop server end of the system framework layer; The resolution-controllable remote desktop image redirection method realizes two functions of system resolution dynamic control and system display image data redirection, and satisfies the image transmission requirements in the remote desktop environment.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an Android system server, a remote desktop image redirection method and system. Background technique [0002] Traditional remote desktop technology is mainly based on PC operating systems such as Windows, Linux, and MacOS. However, with the large-scale application of smart mobile devices and the popularity of enterprise mobile offices, remote desktops based on mobile operating systems such as Android systems have become more and more popular. Many market demands. Compared with the traditional remote desktop, the remote desktop based on the Android system delivers the entire Android desktop to the user, and has the redirection function of hardware devices such as images, audio, and cameras. [0003] In the Android system, the desktop image is a very important and complex basic function, so in the Android remote desktop environment, the perfection of the image redirection f...
