A host captioning device converts the presenter's speech to text and communicates the text to and for presentation by an audience member's client device. The communication session between the host captioning device and the client device is established by an invitation request from the host captioning device in response to a registration request from the client device. The captioning information may be communicated in real time as text. The host captioning device either connects to a network or provides one itself, thereby serving as an access point for the client devices. ## Claims ### Claim 1 A method of communicating caption information to a client device, comprising: sending an invitation to the client device for establishing a communication session in response to a registration message received from the client device; and sending caption information to the client device via the communication session. ### Claim 2 (depends on 1) The method of claim 1 wherein the sending of the caption information to the client device is in real time ### Claim 3 (depends on 1) The method of claim 1 further comprising: sending a Session Initiation Protocol (SIP) INVITE request to the client device for establishing a SIP session in response to a SIP REGISTER request received from the client device. ### Claim 4 (depends on 3) The method of claim 3 further comprising: sending the caption information to the client device using Real-Time Transport Protocol. ### Claim 5 (depends on 1) The method of claim 1 further comprising: receiving an audio signal representing the speech of a live presentation: and converting the audio signal to text for sending to the client device. ### Claim 6 (depends on 1) The method of claim 1 wherein the invitation to the client device is automatically sent on registration of the client device. ### Claim 7 A system for providing caption information to a client device, comprising: a communications module configured to: send an invitation to the client device for establishing a communication session in response to a registration message received from the client device; and send caption information to the client device via the communication session. ### Claim 8 (depends on 7) The system of claim 7 further configured to: send the caption information to the client device real time. ### Claim 9 (depends on 7) The system of claim 7 further configured to: send a Session Initiation Protocol (SIP) INVITE request to the client device for establishing a SIP session in response to a SIP REGISTER request received from the client device. ### Claim 10 (depends on 9) The system of claim 9 further configured to: send the caption information to the client device using Real-Time Transport Protocol. ### Claim 11 (depends on 7) The system of claim 7 further configured to: receive an audio signal representing the speech of a live presentation; and convert the audio signal to text for sending to the client device. ### Claim 12 (depends on 7) The system of claim 7 wherein the invitation to the client device is automatically sent on registration of the client device. ### Claim 13 A method of receiving caption information from a captioning device, comprising: sending a registration message to the captioning device; receiving an invitation message from the captioning device for establishing a communication session in response to the registration message sent to the captioning device; and receiving the caption information from the captioning device via the communication session. ### Claim 14 (depends on 13) The method of claim 13 further comprising: receiving the caption information from the captioning device in real time. ### Claim 15 (depends on 11) The method of claim 11 further comprising: sending a Session Initiation Protocol (SIP) REGISTER request to the captioning device; and receiving a SIP INVITE request from the captioning device for establishing a SIP session in response to the SIP REGISTER request sent to the captioning device. ### Claim 16 (depends on 15) The method of claim 15 further comprising: receiving the caption information from the captioning device using Real-Time Transport Protocol. ### Claim 17 (depends on 13) The method of claim 13 further comprising: presenting the caption information received from the captioning device. ### Claim 18 A system for receiving caption information from a captioning device, comprising: a communications module configured to: send a registration message to the captioning device; receive an invitation from the captioning device for establishing a communication session in response to the registration message sent to the captioning device; and receive caption information from the captioning device via the communication session. ### Claim 19 (depends on 18) The system of claim 18 further configured to: receive caption information from the captioning device in real time. ### Claim 20 (depends on 18) The system of claim 18 further configured to: send a Session Initiation Protocol (SIP) REGISTER request to the captioning device; and receive a SIP INVITE request from the captioning device for establishing a SIP session in response to the SIP REGISTER request sent to the captioning device. ### Claim 21 (depends on 20) The system of claim 20 further configured to: receive the caption information from the captioning device using Real-Time Transport Protocol. ### Claim 22 A method of facilitating the communication of caption information, comprising: advertising the Internet Protocol address or network name of a host device for at least one client device to register with the host device to receive real-time captioning information of a live performance via a multi-party conversation.
