Priority of uplink streams in video switching
First Claim
1. A switching server for controlling uplink video streams in a video conference connecting a first terminal to a plurality of second terminals via the switching server, the switching server being configured for receiving a plurality of uplink video streams from the first terminal via a single transport path and for sending a downlink video stream based on an uplink video stream of the plurality of uplink video streams to each of the second terminals, the switching server further being configured to:
- collect information relating to the use of each of the second terminals, wherein collecting the information further comprises;
(i) transmitting a request to a Home Subscriber Server (HSS) for subscription information regarding each of the second terminals and (ii) receiving the subscription information from the HSS;
determine an order between the plurality of uplink video streams based on the information;
generate instructions for the first terminal to adjust the plurality of uplink video streams based on the order; and
inform the first terminal of the instructions.

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.

20. A switching server for controlling uplink video streams in a video conference connecting a first terminal to a plurality of second terminals via the switching server, the switching server being configured for receiving a plurality of uplink video streams from the first terminal via a single transport path and for sending a downlink video stream based on an uplink video stream of the plurality of uplink video streams to each of the second terminals, wherein the switching server comprises a processor and a memory, the memory containing instructions executable by the processor whereby the switching server is operative to:
-
collect information relating to use of each of the second terminals, wherein collecting the information further comprises;
(i) transmit a request to a Home Subscriber Server (HSS) for subscription information regarding each of the second terminals and (ii) receive the subscription information from the HSS;determine an order between the plurality of uplink video streams based on the information; generate instructions for the first terminal to adjust the plurality of uplink video streams based on the order; and inform the first terminal of the instructions.
