Abstract:
A method relating to a video conference connecting a first terminal to a plurality of second terminals via a switching server is disclosed. The switching server receives a plurality of uplink video streams from the first terminal via a single transport path, and the switching server sends a downlink video stream based on the uplink video streams to each of the second terminals. The method involves the steps of collecting information relating to the use of each of the second terminals and determining an order between the uplink video streams based on the information. The method further involves the steps of generating instructions for the first terminal to adjust the plurality of uplink video streams based on the order, and informing the first terminal of the instructions. A switching server and a first terminal involved in the method are also disclosed.
