Embodiment 1

[0048] The steps of the video conferencing network flow control method are as follows:

[0049] Step 201: Detecting the network traffic condition of the video conference;

[0050] Step 202: According to the video conference network traffic status, judge whether to control the video conference network traffic; if controlled, go to step 203 and step 204;

[0051] Step 203: Notify the non-broadcast source terminal and the non-broadcast source selection terminal to stop sending video data;

[0052] Step 204: Encoding and decoding only the video conference data of the broadcast source terminal and the broadcast source selection terminal;

[0053] Wherein, the execution sequence of step 203 and step 204 is not limited.

[0054] The present invention provides a video conferencing network flow control method. When the network condition is bad, after carrying out the flow control, when the network flow condition recovers to a good condition, the flow control is released, and the data...

Embodiment 2

[0056] After the video conferencing network flow control, the steps to release the flow control are as follows:

[0057] Step 301: Detecting the network traffic condition of the video conference;

[0058] Step 302: According to the traffic status of the video conference network, judge whether to release the control of the video conference network traffic; if the control is released, proceed to steps 303 and 304;

[0059] Step 303: notify all terminals to resume normal video conference data transmission;

[0060] Step 304: Resume encoding and decoding of video conference data of all terminals;

[0061] Wherein, the execution sequence of step 303 and step 304 is not limited.

[0062] Further, the video conference network traffic status is obtained according to the evaluation of the video conference network data receiving and / or sending status;

[0063] For example, it can be determined from one or more of the following:

[0064] Bandwidth occupancy rate, network delay and pack...

Embodiment 3

[0068] Examples of network data reception and / or transmission status are as follows:

[0069] bandwidth utilization network delay Packet loss rate Situation 1 60％ 20ms 5％ Situation 2 30％ 10ms 10％ Situation 3 30％ 5ms 5％ Situation 4 70％ 10ms 8％ Situation 5 20％ 5ms 5％

[0070] Determining the video conference network traffic status according to the above video conference network data receiving and / or sending status may be:

[0071] Video conference network traffic status = bandwidth occupancy rate * 100;

[0072] It is concluded that the video conference network traffic conditions in the above five situations are: 60 in situation 1, 30 in situation 2, 30 in situation 3, 70 in situation 4, and 20 in situation 5.

[0073] Or, according to the comprehensive calculation of some factors of the above-mentioned video conference network data receiving and / or sending status to determine the video conference network traffic ...

Abstract

The invention provides a video conference network flow control method and system. The method comprises the following steps: detecting a video conference network flow condition; judging whether the video conference network flow needs to be controlled according to the video conference network flow condition; if so, notifying a non-broadcast source terminal and a non-broadcast source selection terminal to stop sending video data; and only carrying out encoding and decoding processing on the video conference data of a broadcast source terminal and a broadcast source selection terminal.

Description

technical field [0001] The invention relates to the field of communication, in particular to a method and system for controlling flow of a video conference network. Background technique [0002] With the continuous development of Internet technology and image processing technology, video conferencing system has been gradually developed and applied. The use of video conferencing systems based on multiple network transmissions has greatly improved the convenience of people's work and life communication, especially greatly improved work efficiency and reduced the cost of corporate meetings, and has been gradually popularized and widely used in various fields. [0003] At present, in the commonly used video conferencing system, when a conference is held, all the terminals in the meeting send their own audio and video data to the multipoint control unit (MCU), and the MCU compiles the audio and video data after receiving the audio and video data of each terminal. Decode it and s...
