Abstract

A multimedia transaction between a local and a remote transaction systems (10 and 12) is facilitated by a multimedia interface (16) within each system. The multimedia interface (16) associated with each transaction system serves to signal a telephone (18, 20) associated with the other transaction system to go off hook while the transaction systems are exchanging data when a voice conversation between the transaction systems is desired. Further, the multimedia interface (16) serves to convert the analog speech from the telephone of its associated transaction system into digital voice packets for transmission with the digital signals to the other the transaction system. Also, each multimedia interface converts the digital voice packets received at its associated transaction system from the other transaction system into analog voice information for receipt at the associate telephone.

Claims

1. A method for facilitating a multimedia transaction between a first and second party across a communications channel, comprising the steps of:

establishing a data link across the communications channel between a first computer associated with the first party and a second computer associated with the second party;

exchanging non-voice digital data between the first and second computers;

going off-hook on a first telephone directly connected to the first computer so that the first telephone communicates directly with the first computer;

transmitting a signal from the first computer to the second computer to cause the second computer to signal the second party to go-off-hook on a second telephone directly connected to the second computer so that said second telephone, once off-hook, now communicates directly with said second computer;

receiving analog voice information at the first and second computers from the first and second telephones, respectively;

converting, at the first and second computers, the analog voice information into digital voice packets for transmission with the digital data to each of the second and first computers, respectively, and

converting, at each of the first and second computers, the digital voice packets into analog voice signals for receipt by each of the first and second telephones, respectively, while said first and second computers are exchanging non-voice digital data.

2. The method according to claim 1 wherein the digital data and the digital voice packets are transmitted across the communication channel in an analog format.

3. The method according to claim 1 wherein the digital data and the digital voice packets are transmitted across the communication channel in a digital format.

4. The method according to claim 1 wherein the data link is established across the communications channel through interconnected networks.

5. The method according to claim 4 wherein the interconnected networks comprise the INTERNET.

6. The method according to claim 1 wherein the digital data includes text.

7. The method according to claim 1 wherein the digital data includes graphics.

8. The method according to claim 1 wherein analog voice information from each of the first and second telephones is transmitted via each of the first and second computers, respectively, to a Public Switched Telephone Network, without any conversion to digital voice packets, during intervals other than when a data link is established across the communications channel between the first and second computers.

9. A method for facilitating a multimedia transaction between a first and second party across a communications channel, comprising the steps of:

communicating data across the communications channel between a first computer associated with the first party and a second computer associated with the second party so that the first and second computers exchange non-voice digital data between themselves;

carrying a signal from the first computer to the second computer in response to an off-hook condition of a first telephone directly connected to the first computer so that the first telephone communicates directly with the first computer, the signal carried from the first computer to the second computer causing the second computer to signal the second party to go-off-hook on a second telephone directly connected to the second computer so that said second telephone, once off-hook, now communicates directly with said second computer;

receiving from the first and second computers digital voice packets for transmission to the second and first computers, respectively, the digital voice packets received from the first and second computer representing analog speech signals from the first and second telephone sets digitized by said first and second computers, respectively, and combined with the digital data to each of the second and first computers, respectively, the digital voice packets passing between the first and second computers while said first and second computers exchange non-voice digital data.
