Abstract: A service control is downloaded and installed. First software information installed by the user system is uploaded by the service control to a cloud server side. The first software information includes a software list, or the software list and personalized configuration files of each software. When needing to restore the user system, second software information of the user system is obtained from the cloud server side. Software of the user system is installed, based on the second software information obtained from the cloud server side.

Abstract: The invention provides a method and device for video predictive encoding.

Abstract: A method, system and apparatus for uploading and downloading a caption file are disclosed. The method includes: receiving, by a caption server, file information of a multimedia file and file information of a caption file corresponding to the multimedia file from a client end player; determining, by the caption server, whether the caption server has the caption file according to the file information of the caption file and transmitting a status message indicating whether the caption server has the caption file to the client end player, to enable the client end player to upload the caption file when determining according to the status message that the caption server does not have the caption file. In the solution of the present disclosure, the client end player can upload and download the caption file automatically. The user does not need to search for and download the caption file manually, which improves the user's experience and saves resources of the caption server.

Abstract: An embodiment of the invention provides a method for video predictive encoding. Firstly, extract a pixel block from current frame, divide the pixel block into a principal set of pixels and a complementary set of pixels; encode the principal set of pixels, output code stream of the principal set of pixels, obtain a reconstruction value of the principal set of pixels; interpolate to reconstructed pixel values, which include the reconstruction value of the principal set of pixels, take a result as predictive value of the complementary set of pixels, execute an intra-frame predictive encoding for the complementary set of pixels, output code stream of the complementary set of pixels, obtain a reconstruction value of the complementary set of pixels; and finally combine the reconstruction value of the principal set of pixels and the reconstruction value of the complementary set of pixels, and obtain a reconstruction value of the pixel block.

Abstract: Embodiments of the present invention provide a method and apparatus for voice communication based on an IM system. The method includes: a) establishing a tone-modified voice communication channel between second IM client and first IM client; b) processing inputted original voice information through tone modification to obtain tone-modified voice; sending the tone-modified voice to the first IM client via the tone-modified voice communication channel. According to embodiments of the present invention, the voice information collected in the IM system is first processed through tone modification, thereby tone-modified voice communication based on the IM system is implemented.

Abstract: The embodiment of the present invention provides a method for establishing P2P connection, comprising the steps of: a first terminal initiating connection sends a message to a second terminal to be connected, wherein the message contains the address of the first terminal; the second terminal reads the address of the first terminal initiating connection upon receiving the message, and initiates a P2P connection to the address of the first terminal. The embodiment of the present invention also provides another method for establishing P2P connection, through which both UDP P2P connection and TCP P2P connection can be established.

Abstract: The present invention relates to video communication technology and discloses a system and method for generating animated video images. The present invention provides a system for generating animated video images, including a video image capture module, an animation capture module and an overlay module, for the purpose of overcoming the disadvantages of current video interaction system, such as poor video interaction experience and dull images. The present invention also provides a method for generating animated video images, comprising capturing video images, obtaining animation frames and overlaying the video images with the animation frames.
