Method and device for processing media streams between a plurality of media terminals and a processing unit all connected to one another over a communication network
The media stream processing device between a plurality of media terminals (UA, UB, UC, UD) and a processing unit (UV) over a communication network. The processing unit (UV) is capable of sending a media stream transmission pause/resume command signal in the format of a RTP/RTCP real-time communication protocol or equivalent intended for at least one media terminal in response to a chosen event.
1. A method for processing media streams between a plurality of media terminals and a processing unit over a communication network, the method comprising, by the processing unit:
receiving, from each of the media terminals, corresponding media streams comprising video transmission and audio transmissions;
monitoring sound activity of each of the media terminals from the audio transmissions;
selecting the N loudest participants based on the monitored sound activity, wherein the selected participants are identified as active participants and non-selected participants are identified as non-active participants;
pausing audio transmissions while permitting video transmissions from the non-active participants by transmitting a first pause signal to the non-active participants to pause the audio transmissions from the non-active participants;
receiving a request from a moderator terminal to permit a selected non-active participant terminal to resume audio transmissions in addition to the video transmissions;
in response to the request, transmitting a resume signal to the selected non-active participant terminal and transmitting a second pause signal to one or more active participants to pause both audio and video transmissions,
wherein the resume signal, first pause signal, and second pause signal are in the form of and RTP/RTCP real-time communication protocol.
2. A method according to claim 1 , wherein the processing unit comprises a module to monitor the sound activity of media terminals.
3. A method according of claim 2 , wherein the processing unit sends a command signal capable of pausing/resuming the transmission of the media stream depending on the sound activity of said media terminal.
4. A method according to claim 1 , wherein the processing unit comprises a reception module capable of receiving a chosen request and is configured to send a command signal capable of pausing/resuming the transmission of the media stream.
5. A device comprising a processor for processing media streams between a plurality of media terminals and the processor over a communication network, wherein said processor is configured to:
receive, from each of the media terminals, corresponding media streams comprising video transmission and audio transmissions;
monitor sound activity of each of the media terminals from the audio transmissions;
select the N loudest participants based on the monitored sound activity, wherein the selected participants are identified as active participants and non-selected participants are identified as non-active participants;
pause audio transmissions while permitting video transmissions from the non-active participants by transmitting a first pause signal to the non-active participants to pause the audio transmissions from the non-active participants;
receive a request from a moderator terminal to permit a selected non-active participant terminal to resume audio transmissions in addition to the video transmissions;
in response to the request, transmit a resume signal to the selected non-active participant terminal and transmit a second pause signal to one or more active participants to pause both audio and video transmissions,
wherein the resume signal, first pause signal, and second pause signal are in the form of an RTP/RTCP real-time communication protocol.
