Method for handling larger number of people per conference in voice conferencing over packetized networks
View Patent ↗The present invention is directed to a system and method for handling larger number of people per conference in voice conferencing over packetized networks. A method for providing a conferencing session may include receiving inputs from a number of participants in a conferencing session. The received inputs are combined into an output packet including at least two sub-packets. The sub-packets having payloads including mixed received inputs from the number of participants. The payloads of at least two of the sub-packets contain different mixed received inputs.
1. A method for providing a conferencing session, comprising:
receiving inputs from a number of participants in a conferencing session;
determining a number of prominent inputs from the received inputs, the inputs being determined as prominent based upon voice clarity and voice loudness;
combining prominent inputs into an output packet including a first sub-packet and a second sub-packet, wherein the first sub-packet has a first payload and the second sub-packet has a second payload, the first payload and the second payload including inputs combined from at least a portion of the received inputs from the number of participants, wherein the first payload includes at least one received input that is not included in the second sub-packet; and
configuring the sub-packets in the output packet so that upon receipt of the output packet by a participant, the participant examines the packets and output a first examined sub-packet which does not include an indication that the sub-packet includes content received from the participant, the output packet being configured as a UDP packet which encapsulates the first sub-packet and the second sub-packet, the first sub-packet and the second sub-packet configured as RTP packets.
2. The method as described in claim 1 , wherein the determined prominent inputs are utilized to provide the first payload for the first sub-packet and the second payload for the second sub-packet.
3. The method as described in claim 2 , wherein inputs are determined as prominent based upon a characteristic including at least one of signal strength and prominence history.
4. The method as described in claim 1 , wherein the second sub-packet includes at least one received input that is not included in the first sub-packet, wherein the at least one received input that is not included in the first sub-packet includes a next most prominent received input.
5. The method as described in claim 1 , wherein the first sub-packet and the second sub-packet include headers indicating originating participants of the first payload and the second payload.
6. The method as described in claim 1 , further comprising transmitting the output packet to at least a portion of the number of participants in the conferencing session utilizing a multicast IP address.
7. A method for providing a conferencing session, comprising:
receiving inputs from a number of participants in a conferencing session;
determining a number of prominent inputs from the received inputs, the inputs being determined as prominent based upon voice clarity and voice loudness;
combining prominent inputs into an output packet including at least two sub-packets, the sub-packets having payloads including mixed received inputs from the number of participants, wherein the payloads of at least two of the sub-packets contain different mixed received inputs; and
configuring the sub-packets in the output packet so that upon receipt of the output packet by a participant, the participant examines the packets and outputs a first examined sub-packet which does not include an indication that the sub-packet includes content received from the participant, the output packet being configured as a UDP packet which encapsulates the first sub-packet and the second sub-packet the first sub-packet and the second sub-packet configured as RTP packets.
8. The method as described in claim 7 , wherein the determined prominent inputs are utilized to provide the payloads for the sub-packets.
9. The method as described in claim 8 , wherein inputs are determined as prominent based upon a characteristic including at least one of signal strength and prominence history.
10. The method as described in claim 7 , wherein the sub-packets include headers indicating originating participants of the first payload and the second payload.
11. The method as described in claim 10 , wherein the headers are contributing sources (CSRC) headers.
12. The method as described in claim 7 , further comprising transmitting the output packet to at least a portion of the number of participants in the conferencing session utilizing a multicast IP address.
13. A conferencing system suitable for providing a conferencing session to a plurality of participants, comprising:
a multipoint conferencing unit communicatively coupled over a packetized connection to a plurality of input/output devices as utilized by a number of participants so as to enable the participants of a conferencing session to interact, wherein the multipoint conferencing unit is configured to
receive inputs from the input/output devices in a conferencing session;
determine a number of prominent inputs from the received inputs, the inputs being determined as prominent based upon voice clarity and voice loudness;
combine prominent inputs into an output packet including a first sub-packet and a second sub-packet, wherein the first sub-packet has a first payload and the second sub-packet has a second payload, the first payload and the second payload including inputs combined from at least a portion of the received inputs from the number of participant, wherein the first payload includes at least one received input that is not included in the second sub-packet; and
configure the sub-packets in the output packet so that upon receipt of the output packet by a participant, the participant examines the packets and outputs a first examined sub-packet which does not include an indication that the sub-packet includes content received from the participant, the output packet being configured as a UDP packet which encapsulates the first sub-packet and the second sub-packet, the first sub-packet and the second sub-packet configured as RTP packets.
14. The conferencing system as described in claim 13 , wherein the determined prominent inputs are utilized to provide the first payload for die first sub-packet and the second payload for the second sub-packet.
15. The conferencing system as described in claim 14 , wherein inputs are determined as prominent based upon a characteristic including at least one of signal strength and prominence history.
16. The conferencing system as described in claim 13 , wherein the second sub-packet includes at least one received input that is not included in the first sub-packet, wherein the at least one received input that is not included in the first sub-packet includes a next most prominent received input.
17. The conferencing system as described in claim 13 , wherein the first sub-packet and the second sub-packet include headers indicating originating participants of the first payload and the second payload.
18. The conferencing system as described in claim 13 , wherein the multipoint conferencing system further transmits the output packet to at least a portion of the number of participants in the conferencing session utilizing a multicast IP address.
