Method and system for transmitting a multimedia stream
DCFirst Claim
1. A method, wherein a gateway is capable of communicating with a first terminal and a second terminal, the method comprising:
- the gateway or the first terminal using a first protocol to exchange first multimedia session information between the first terminal and the gateway, wherein the exchange of the first multimedia session information sets up a first media stream from the first terminal, and wherein the first multimedia session information includes a type of media;
the second terminal using a second protocol to receive a trigger provided by the gateway or first terminal, wherein the trigger is to initiate an exchange of second multimedia session information between the gateway and the second terminal, and wherein the trigger serves to inform the second terminal of availability of a new multimedia stream;
in response to receiving the trigger, the second terminal using a third protocol to initiate the exchange of the second multimedia session information between the gateway and the second terminal, wherein the exchange of the second multimedia session information sets up a second media stream to the second terminal in which the second terminal participates; and
the second terminal receiving the second media stream, wherein the second media stream is associated with the first media stream.

Abstract
A method is described for transmitting a multimedia stream from a first terminal and receiving an associated second multimedia stream at a second terminal. The first and second terminal are connected to at least one gateway for enabling the transmission of the stream and the receiving of the associated stream. The method comprises: —initiating the exchange of first multimedia session information between the first terminal and the gateway, using a first protocol; —providing a trigger to the second terminal to initiate the exchange of second multimedia session information between the second terminal and the gateway, using a second protocol; —in response to providing the trigger, the second terminal initiating the exchange of second multimedia session information between the second terminal and the gateway, using a third protocol; —transmitting a first multimedia stream from the first terminal and receiving a second associated multimedia stream at the second terminal.

16. An article of manufacture including a non-transitory computer-readable medium, having stored thereon software instructions that, if executed by a computing device, cause the computing device to perform operations comprising:
-
using a first protocol to initiate an exchange of first multimedia session information between a first terminal and a gateway, wherein the exchange of the first multimedia session information sets up a first media stream from the first terminal, and wherein the first multimedia session information includes a type of media; using a second protocol to provide a trigger to a second terminal, wherein the trigger is to initiate an exchange of second multimedia session information between the gateway and the second terminal, and wherein the trigger serves to inform the second terminal of availability of a new multimedia stream; using a third protocol to conduct the exchange of the second multimedia session information between the gateway and the second terminal, wherein the exchange of the second multimedia session information sets up a second media stream to the second terminal in which the second terminal participates; and using the first protocol to transmit a response to the first terminal, wherein the response causes the first terminal to begin transmission of the first media stream from the first terminal, wherein the second media stream to the second terminal is associated with the first media stream from the first terminal.

17. A gateway comprising:
-
a communication interface; and memory that stores software instructions that, when executed by the gateway, cause the gateway to; (i) exchange first multimedia session information with a first terminal using a first protocol, wherein the exchange of the first multimedia session information sets up a first media stream from the first terminal, and wherein the first multimedia session information includes a type of media, (ii) provide a trigger to a second terminal, wherein the trigger is provided using a second protocol, in response to which the second terminal is able to initiate exchange of second multimedia session information with the gateway, and wherein the trigger serves to inform the second terminal of availability of a new multimedia stream, and (iii) exchange second multimedia session information with the second terminal, using a third protocol, wherein the third protocol is different from the first protocol, wherein the exchange of the second multimedia session information sets up a second media stream to the second terminal in which the second terminal participates. - View Dependent Claims (18, 19, 20, 21, 22)
