Abstract

A video call distribution and method provides the user of a video station with access to a video network conferencing station without human operator assistance, even if the communication protocols of the user video station are incompatible with those of the video network conferencing system. Access is provided by remote user transmitted DTMF (or voice) signals, which signals are converted into compatible protocols in real time.

Claims

1. A video call distribution apparatus, comprising:

a video conferencing network of video stations accessible for communication with each other;

at least one user communication station including an interface that generates dual tone modulated frequency (DTME) signals, each of said video conferencing network and said one user communication station having respective communication protocols;

a graphic user interface between the network and remote user communication station that generates real time continuous audio visual data output;

a video encoder that encodes the output of the graphic user interface into video signals;

a transmitter that transmits the video signals in real time to said remote user communication station, so as to produce a video display at the user communication station;

a DTMF converter that converts the DTMF signals to a designation that has a format compatible with the video conferencing network, the designation being indicative of a destination one of the video stations of the video conferencing network, the destination one of the video stations being responsive to the designation to connect with the user communication station;

a video switch; and

a codec that determines whether the communication protocols of said video conferencing network and the user communication station are compatible and, if so, directly connects the video conferencing network with the user communications station, but if not, connects the user communication station with the video switch, the video switch being responsive to connection with the user communication station being established by the codec to transmit a prompt to the user communication station and, in response to a reply to the prompt from the user communication station, placing a call to an appropriate destination one of the video stations.

2. An apparatus as in claim 1, wherein the video switch is responsive to an answer from the destination one of the video stations to disconnect, leaving the user communication station and the destination one of the video stations in contact with each other.

3. A video call distribution apparatus, comprising:

a video conferencing network of video stations accessible for communication with each other;

at least one user communication station including a microphone interface that generates signals indicative of voice;

a graphic user interface between the network and remote user communication station that generates real time audio visual data output;

a video encoder that encodes the output of the graphic user interface into a video signal;

a transmitter that transmits the video signal in real time to said user communication station, so as to produce a video display at the user communication station;

a converter that converts voice into an electrical signal at the user communication station and transmits the same;

voice recognition software that receives the electrical signal and makes a recognition of the destination one of the video stations from the received electrical signal, the destination one of the video stations being responsive to the recognition of the destination by the voice recognition software to connect with the remote user communication station;

a video switch;

a codec that determines whether communication protocols of said video conferencing network and the remote user communication station are compatible and, if so, directly connects the video conferencing network with the remote user communication station, but if not, connects the user communication station with the video switch, the video switch being responsive to connection with the user communication station being established by the codec to transmit a prompt to the user communication station and, in response to a rely to the prompt from the user communication station, placing a call to an appropriate destination one of the video stations.

4. An apparatus as in claim 3, wherein the video switch is responsive to an answer from the destination one of the video stations to disconnect, leaving the user communication station and the destination one of the video stations in contact with each other.

5. A method of distributing a video call, comprising:

providing a plurality of video stations on a video conferencing network, the video stations communicating with each other;

determining whether communication protocols of the video conferencing network and a remote user communication station are compatible;

identifying a designation of a destination one of the video stations from the communication protocols provided the step of determining finds that the communication protocols are compatible with each other;

transmitting a prompt to the remote user communication station provided the step of determining finds that the communication protocols are incompatible with each other;

identifying the designation of a destination one of the video stations from the communication protocols in response to a reply from the prompt by the remote user communication station; and

directly connecting the remote user communication station with the destination one of the video stations in accordance with the designation.

6. A method as in claim 5, further comprising

generating real time audio visual data output with a graphic user interface between the video conferencing network and the remote user communication station;

encoding the output of the graphic user interface into a video signal;

transmitting the video signal in real time to said remote user communication station, so as to produce a video display at the remote user communication station; and

generating dual tone modulated frequency (DTMF) signals with the remote user communication stations the step of making the identification including converting the DTMF signals into a designation having a format compatible with the video conferencing network, the designation being indicative of a destination one of the video stations of the video conferencing network, the step of directly connecting including connecting the remote user communication station with the destination one of the video stations based on the designation.

7. A method as in claim 5, further comprising:

generating real time audio visual data output with a graphic user interface between the video conferencing network and the remote user communication station;

encoding the output of the graphic user interface into a video signal;

transmitting the video signal in real time to said remote user communication station, so as to produce a video display at the remote user communication station;

converting voice into an electrical signal at the remote user communication station and transmitting the same; and

receiving and processing the electrical signal with voice recognition software to recognize a designation of the destination one of the video stations, the steps of making an identification and directly connecting taking place by connecting the remote user communication station with the destination one of the video stations based on the recognition of the designation by the voice recognition software.

8. A method as in claim 6, further comprising the step of placing a call to the destination one of the video stations in accordance with the designation, answering the call with the destination one of the video stations, and, thereafter in response to the answering, establishing the connection between the remote user communication station and the destination one of the video stations.
