Problems solved by technology

[0007] However, the remote frame buffer technology can only provide remote desktop image information, but cannot extract window information from the desktop image information, that is, it cannot restore the window of the application program on the local client, making the control of the server-side application program on the client side Feelings can't be as real as they are on the server side

Embodiment Construction

[0024] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

[0025] Such as figure 2 As shown, it is a schematic diagram of the overall framework for implementing the remote frame buffer-based window restoration method of the present invention.

[0026] Compared with the general framework of the remote frame buffer technology in the prior art, the window restoration method based on the remote frame buffer of the present invention includes steps (combining figure 2 steps 1-5 of and image 3 ):

[0027] Step 301: extracting image frame buffer data from the X11 data generation layer on the server side;

[0028] Step 302: capture the application window information data from the X11 layer window manager at the server end, the application window information data includes the ID, coordinates, status and type of the window; wherein, the ID of the window is the unique identification of the window, and the coordinates...

Abstract

The invention discloses a window restoring method based on remote frame buffering. The method includes steps of extracting image frame buffering data from an X11 data generation layer of a server side; capturing application window information data from an X11 layer window manager of the server side, wherein the application window information data include identities (IDs), coordinates, states and types of all application program windows which are in operation on the server side; transmitting the image frame buffering data and the application window information data from the server side to a local client side; and restoring images of the application program windows which are in operation at a long distance according to the image frame buffering data and the application window information data in the local client side. By means of the window restoring method based on remote frame buffering, long-distance application windows can be checked and controlled on the local client side so that virtualization of application programs is achieved.

Description

[0001] technical field [0002] The invention relates to the communication field, in particular to a window restoration method based on remote frame buffer. [0003] Background technique [0004] Such as figure 1 The above is a schematic diagram of an overall framework of a traditional remote frame buffer technology. Remote frame buffer technology, commonly referred to as RFB technology internationally, is a mature technology that can access remote computer desktop environments. The application of RFB technology on unix / linux and other operating systems is mainly based on the x11 standard visualization environment. RFB technology includes related links such as collection, encoding, transmission, decoding and restoration of desktop images. [0005] For the desktop image information on the remote server side: the image frame buffer data on the remote server side is extracted from the X11 data generation layer (the bottom layer), encoded by the encoding layer, and then trans...
