Abstract

Methods and devices for remote hosting of applications across operating system are disclosed. In particular, a second application may be launched and run remotely on a remote server running a first operating system, and the screen images of the second application may be rendered in a first application on a terminal device running a second operating system. In one implementation, a launching instruction may be sent by the terminal device through the first application to the remote server. The second application may then be launched in the remote server. Rendering parameters comprising API functions and API parameters may then be obtained in real-time during the running process of the second application. A rendering instruction containing the rendering parameters may then be sent to the first application in the terminal device for instructing the first application to render the screen images on the terminal device.

First claim

What is claimed is:

1. A method for remote application hosting by a server comprising a processor, the method comprising:
receiving a launching instruction sent by a terminal device through a first application running on a first operating system supported in the terminal device, wherein the launching instruction comprises an identifier for a second application;
launching the second application in the server in a second operating system supported by the server according to the identifier, wherein the second operating system is different from the first operating system;
obtaining rendering parameters for rendering a current frame of screen image of the second application in real-time while the second application is running on the server by:
obtaining first rendering parameters for the current frame;
obtaining second rendering parameters for a previous frame of the current frame;
determining whether a similarity between the first rendering parameters for the current frame and the second rendering parameters of the previous frame of the current frame reaches a preset threshold;
using the first rendering parameters as the rendering parameters for the current frame if the similarity does not reach the preset threshold; and
using a differential rendering parameter between the first rendering parameters and the second rendering parameters as the rendering parameters for the current frame if the similarity reach the preset threshold,
wherein the rendering parameters comprise at least one application program interface (API) function and corresponding parameters for rendering the current frame of the screen image of the second application on the terminal device; and

sending a rendering instruction to an access point of the first application running on the terminal device, wherein the rendering instruction comprises the rendering parameters and is used for instructing the first application running on the terminal device to render the current frame of the screen image of the second application according to the rendering parameters.

2. The method according to claim 1 , wherein obtaining the rendering parameters for the current frame of the screen image comprises:
obtaining the at least one API function and the corresponding API parameters for rendering the current frame of the screen image in real-time using a hook function in a running process of the second application.

3. The method according to claim 1 , wherein sending the rendering instruction to the access point of the first application on the terminal device comprises:
sending a rendering instruction of a first type to the terminal device if the rendering parameters comprise the first rendering parameters, the rendering instruction of the first type being used for instructing the first application on the terminal device to render the current frame of the screen images according to the first rendering parameters; and
sending a rendering instruction of a second type to the terminal device if the rendering parameters comprises the differential rendering parameters, the rendering instruction of the second type being used for instructing the first application on the terminal device to render the current frame of the screen image according to the differential rendering parameters and the second rendering parameters.

4. The method according to claim 1 , wherein launching the second application according to the identifier of the second application comprises:
determining the second operating system needed by the second application according to the identifier, identifying a target server running the second operating system as the server from a server cluster, and running the second application on the target server; or
determining the second operating system needed by the second application according to the identifier, identifying a target virtual machine running the second operating system from at least one virtual machine running by the server, and running the second application on the target virtual machine.

5. The method according to claim 1 , further comprising:
responding to an operating instruction to control the screen images of the second application on the server, wherein the operating instruction is generated by capturing, by the terminal device, user operation on rendered frame of screen images on by the first application.

6. The method according to claim 1 , wherein the rendering instruction is an instruction which is subject to data compression processing.

7. A remote application running method implemented by a terminal device and comprising:
sending a launching instruction to a remote server through a first application running on a first operating system supported in the terminal device, the launching instruction comprises an identifier for a second application and causes the remote server to launch the second application on a second operating system running on the remote server, wherein the second operating system is different from the first operating system;
receiving a rendering instruction sent by the remote server, via a access point of the first application running on the terminal device, the rendering instruction carrying rendering parameters, wherein:
the rendering parameters comprise a first rendering parameters for a current frame of screen image of the second application when a similarity between the first rendering parameters and second rendering parameters of a previous frame of the current frame of the second application does not reach a preset threshold;
the rendering parameters comprise differential rendering parameters between the first rendering parameters and the second rendering parameters when the similarity between the first rendering parameters and the second rendering parameters reaches the preset threshold; and
the rendering parameters comprise at least one application program interface (API) function and corresponding API parameters for rendering, on the terminal device in real-time, the current frame of the screen image of the second application running on the remote server;

extracting the rendering parameters from the rendering instruction; and
rendering the current frame of the screen image in real-time through the first application and according to the rendering parameters.

8. The method according to claim 7 , wherein rendering the current frame of the screen image comprises:
determining a type of the rendering instruction received from the remote server; and
extracting the at least API function and the API parameters carried by the rendering instruction through the first application on the terminal if the rendering instruction is of a first type, invoking the at least one API functions in the rendering parameters in sequence, transmitting the API parameters to the at least one API functions, and rendering the current frame of the screen image on the terminal device; or
extracting the differential rendering parameters carried by the rendering instruction through the first application if the rendering instruction is of a second type, obtaining second rendering parameters from a local storage, combining the differential rendering parameters and the second rendering parameters to obtain the at least one API function and the API parameters, invoking the at least one API functions, transmitting the API parameters to the at least one API function, and rendering the current frame of the screen image on the terminal device.
