Problems solved by technology

However, in the traditional conference system, the entire screen is generally captured directly at fixed time intervals, and then sent to the participants' web conference clients respectively. When the screen resolution is high in this way, due to the large amount of transmitted data, Often cause serious delays, affect user experience, or even fail to use normally

Embodiment 1

[0026] Embodiment one, combining figure 1 As shown, the method for processing a shared desktop in a conference system includes a shared desktop computer and a participant computer, and is characterized in that it includes the following steps,

[0027] Step 1: Take a screenshot of the screen of the shared desktop computer, and obtain a screen image from the screenshot;

[0028] Step 2: Convert the above screen image from color mode to YUV420 data format, and temporarily store the obtained YUV420 data;

[0029] Step 3: Compress the YUV420 data obtained from the above-mentioned temporary storage in the form of H264 encoding to obtain a compressed video data package. In step 3, since the biggest advantage of H264 is its high data compression ratio, compression coding is performed in the form of H264 coding, and the data volume of the video data compression package is smaller, and H264 has a high compression ratio while also With high-quality and smooth images, because of this, t...

Abstract

The invention relates to a processing method for sharing a desktop in a conference system. According to the method, continuous screenshot is carried out on a screen of a shared computer, thereby obtaining screen image data; and operation such as format conversion, coding compaction, and disassembly of the data into frame data is carried out on the screen image data in sequence. According to the method, the coding compaction is carried out on the data in an H264 coding form, the compacted data is disassembled into discrete frame data with relatively low data volume, the discrete frame data is transmitted to each participant computer in a UDP multicast mode, the participant computers receive the discrete frame data and splice the discrete frame data into complete frames through software, and the complete frames are played on the screens of the participant computers, so the transmitted data volume is reduced, bandwidths are greatly reduced and a data transmission speed is fast. One computer can transmit the same message to a plurality of participant computers, so the plurality of computers share the desktop of the computer at a high speed.

Description

technical field [0001] The invention relates to the technical field of computer network conference system and multimedia data processing, in particular to a processing method of shared desktop in the conference system. Background technique [0002] In the electronic network conferencing system, it is often necessary for participants to share computer desktops to demonstrate personal presentation materials and documents. However, in the traditional conference system, the entire screen is generally captured directly at fixed time intervals, and then sent to the participants' web conference clients respectively. When the screen resolution is high in this way, due to the large amount of transmitted data, It often causes serious delays, affects user experience, and even cannot be used normally. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a conference system processing meth...
