Android system service terminal and remote desktop image redirection method and system

Abstract

The invention discloses a remote desktop image redirection system based on the controllable resolution of the Android system. The system includes an Android system service terminal and a remote desktop client, wherein the Android system service terminal includes an Audio Finger process of an emergency response system framework layer, an image hardware abstraction layer module of a hardware abstraction layer, and a remote desktop service terminal of a system framework layer, and the remote desktop client includes a second communication module and an image display module. The invention further provides a remote desktop image redirection method based on the controllable resolution of the Android system by using the system, the two functions, namely system resolution dynamic control and system display image data redirection, are achieved, and the image transmission requirement in the remote desktop environment is met.

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...

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
