Application data supplying method, device and system based on virtual machine

Abstract

The invention discloses an application data supplying method, an application data supplying device and an application data supplying system based on a virtual machine, and solves the problem that a process that the virtual machine supplies application data to a client is influenced by success or failure of the starting of an operating system of the virtual machine in the prior art. According to the device, when detecting that a virtual display card and a virtual sound card of the virtual machine are successfully started, an acquisition module acquires video information in the virtual display card and audio information in the virtual sound card and encodes and sends the information through an encoding module. The acquisition module is independently arranged outside each virtual machine; no matter whether the operating system of the virtual machine is successfully started, the video information displayed on the current interface of the virtual machine and the current played audio information can be sent to the client only if the virtual sound card and the virtual display card are successfully started, so that a user can know the state of the current virtual machine and timely acquire information that the operating system of the virtual machine is successfully started; and therefore, the user can timely operate an application program.

Description

technical field [0001] The present invention relates to the technical field of IPTV, in particular to a method, device and system for providing application data based on a virtual machine. Background technique [0002] With the continuous development of technology, terminals with relatively low configuration can provide users with application data with relatively high configuration requirements, wherein the application data includes audio information and / or video information generated by the running of the application program. This is because in the process of providing application data, the server runs the application program required by the user, encodes the video information currently presented on its own display interface, and the currently played audio information, and sends the encoded video and audio information to The terminal, at this time, the terminal only needs to have the function of decoding and displaying to obtain the audio and video information of the applic...

AI Technical Summary

Problems solved by technology

[0007] According to the current method of obtaining application data by virtual machines, application data can only be obtained after the operating system of the virtual machine is successfully started. unavailable

In the process of starting the virtual machine, when the operating system fails to start normally, and the terminal has established a link with the virtual machine at this time, the virtual machine has been unable to start due to a fault, and the end user cannot obtain the virtual machine. The current display status of the virtual machine causes end users to wait for a long time, and because end users cannot know the current display status of the virtual machine, they cannot know the fault status of the virtual machine, which affects the speed of virtual machine fault recovery
