Problems solved by technology

However, the traditional conference system directly captures the entire screen at fixed time intervals, and then directly distributes it to the participants' web conference clients. When the screen resolution is high, the large amount of transmitted data will cause a large Delay, affecting user experience

Embodiment Construction

[0006] The technical solution of the present invention will be described in further detail below in conjunction with accompanying drawing 1 .

[0007] FIG. 1 is a block diagram of various modules involved in screen sharing in a network conference, which includes two parts, a client and a server. Multiple clients can connect to the server. The client consists of an Applet that runs on the presenter's computer and Flash that displays the shared desktop at the side of the meeting participants. Among them, Applet is the main screen data acquisition module, which includes block manager, screen acquisition, block encoding and sending encoding sub-modules. The server side mainly consists of receiving module, session manager, block manager, frame assembler, frame streaming manager and so on.

[0008] The main steps of this desktop sharing process are as follows:

[0009] 1) The Applet calls the block manager to obtain the resolution of the screen.

[0010] 2) The block manager det...

Abstract

The invention provides a method, which has an independent platform and shares a client side computer desktop at high speed for a netmeeting system, and comprises the following steps: a client side computer screen acquisition module intercepts a screen picture and divides the screenshot into a plurality of different areas; the variation of the picture of the frame is compared with the picture of the previous frame, only the changed picture can be encapsulated and sent to the system server; and a server decompresses and assembles small screen images and recompresses the images into Flash monitor flow and then distributes to all client sides participating in a conference. The mode can greatly save bandwidth, improve the shared speed of netmeeting desktop and better satisfy user experience.

Description

technical field [0001] The invention relates to the technical fields of computer network conference system and multimedia data processing. Background technique [0002] In the electronic network conferencing system, it is often necessary for participants to share computer desktops to demonstrate personal documents or programs. However, the traditional conference system directly captures the entire screen at fixed time intervals, and then directly distributes it to the participants' web conference clients. When the screen resolution is high, the large amount of transmitted data will cause a large Latency affects user experience. Contents of the invention [0003] The purpose of the present invention is to provide a method for high-speed sharing of computer desktops in a network conference system, by reducing the total amount of data that needs to be transmitted in the network conference system, to reduce the change of the speaker's desktop on the computers of different par...
