Embodiment 1

[0052] This embodiment provides a remote desktop image processing method for implementing desktop image transmission, such as Figure 2a As shown, the method includes:

[0053] S1. Step of acquiring graphic instructions: in response to an input event triggered by a user operation, acquiring a graphic instruction related to the user operation.

[0054] When the user performs an input operation on the client side through an input device such as a mouse or a keyboard, the server side responds to the input event triggered by the user operation and obtains the graphics instruction based on the Graphics Device Interface (GDI) provided by the operating system , wherein the graphics instruction includes a vector drawing command; when responding to an input triggered by a user operation, image data may also be acquired, and the image data includes image data of a cursor and image data other than the cursor displayed on the remote desktop.

[0055] S2. The step of obtaining cursor info...

Embodiment 2

[0081] like Figure 3aAs shown, this embodiment also provides a remote desktop image processing device, which includes: a graphics instruction acquisition unit 100 , a cursor information acquisition unit 200 , and an identification unit 300 . In the device of this embodiment:

[0082] The graphic instruction acquiring unit 100 is configured to acquire a graphic instruction related to the user operation in response to an input event triggered by the user operation, and send the graphic instruction to the cursor information acquiring unit 200 .

[0083] When the user performs an input operation on the client side through an input device such as a mouse or a keyboard, the server side responds to the input event triggered by the user operation and obtains the graphics instruction based on the Graphics Device Interface (GDI) provided by the operating system . Among them, graphics instructions include vector drawing commands. When responding to an input triggered by a user operat...

Embodiment 3

[0092] combine Figure 1a , the embodiment of the present invention provides a remote desktop server 106a. like Figure 4a As shown, the remote desktop server 106 a is composed of three major components, namely: a hardware platform 150 , a virtual machine monitor platform (Hypervisor) 151 and a virtual machine execution space 152 . in:

[0093] The hardware platform 150 includes a hard disk 160, a CPU 161, a network card 162, and a memory RAM 163 in the physical structure of the remote desktop server 106a. The virtual machine monitor platform 151 and the virtual machine execution space 152 respectively provide the hardware platform and software platform of the virtual machine. The virtual machine monitor platform 151 includes multiple virtual machine monitors 170a, 170b...170n. The virtual machine monitor platform 151 is an intermediate layer between physical hardware and virtual machines, responsible for coordinating the access of each virtual machine to server hardware. ...

Abstract

The invention discloses a method and device for processing remote desktop images, and relates to the technical field of remote desktops. The method for processing the remote desktop images comprises the steps of obtaining a graph command relevant to user operation in response to an input event triggered by the user operation, obtaining cursor information from the graph command, judging the type of a cursor according to the cursor information, and identifying the type of an operation scene of the user operation according to the cursor information and the judged type of the cursor. By means of the method and device, before the remote desktop images are processed, the type of the scene of the user operation can be identified, accordingly, unnecessary spending produced in the process of sending a large number of image data is effectively lowered, and the transmission bandwidth is optimized.

Description

technical field [0001] The invention relates to the technical field of remote desktops, in particular to a remote desktop image processing method and device. Background technique [0002] Remote desktop technology makes it possible to connect and control another device with remote desktop connection function enabled through the network. Remote desktop technology includes not only the display of remote desktop images, but also the transmission of remote sound and the mapping of pluggable hardware, etc. etc., thus delivering a desktop or application experience with rich fidelity. For client devices such as computers or mobile devices in corporate offices, business halls, hospitals, etc., they can be connected to a data center with a large number of servers through a LAN or WAN. After the remote desktop system, each client device can operate the server device in real time through the remote desktop technology, so as to use the resources of the data center more conveniently and...
