Embodiment Construction

[0046] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

[0047] Such as figure 1 As shown, it is the implementation method of real-time desktop cloud, which includes:

[0048] Use the remote desktop protocol to obtain the desktop image and audio data of the virtual machine, and receive terminal device connection requests and peripheral event data; and process it in time when the resolution of the desktop image changes;

[0049] Encode the acquired desktop image and audio data into a multimedia file format and output it;

[0050] Perform streaming processing on the output multimedia file format data to generate streaming media format data;

[0051] Decode streaming media format data and output desktop image and audio data; and

[0052] Send peripheral event data.

[0053] The above method also include...

Abstract

The invention discloses a method and a system for realizing a real-time desktop cloud. The system comprises a terminal module, a server module, a desktop protocol module, a streaming media coding module, a streaming media service module, a portal module, an execution module and a database; the desktop protocol module acquires a desktop image and audio data from the virtual machine of the server module according to a remote desktop protocol, and then the desktop image and the audio data are transmitted to the terminal module for separate displaying and playing after being coded by the streaming media coding module and streamed by the streaming media service module. The terminal module sends an external device event message to the desktop protocol module and finally transfers the same to the virtual machine. The technical scheme of the present invention provides the method for realizing the real-time desktop cloud; a desktop cloud is deployed on a common assembled PC and an Android cellphone serves as the terminal module; the network time delay is about 0.1-0.3 second, and therefore, good real-time performance can be achieved.

Description

technical field [0001] The invention belongs to the technical field of cloud computing, and in particular relates to a desktop cloud implementation method and system with small network delay and strong real-time performance. Background technique [0002] In the field of desktop cloud technology and application, a virtual machine runs on a remote server, and transmits desktop images and audio data to terminal devices (such as PCs, thin clients, mobile terminals, etc.). The terminal device outputs desktop images and audio signals, and at the same time collects peripheral events of the terminal device (such as typing the keyboard, moving the mouse, etc.) and feeds them back to the virtual machine of the remote server, and the updated desktop image and audio data continue to be transmitted to the terminal device . The real-time nature of the desktop cloud refers to the delay between when a peripheral event occurs on the terminal device, the updated desktop image and audio data ...
