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 ...
