Abstract

For use with a video camera, a television set and a communications network capable of carrying voice and video data, a multimedia telephone that includes a network interface for coupling the multimedia telephone to the communications network. The multimedia telephone further includes a first module, coupled to the network interface and including a user interface for communicating audio information with a user and first module wireless communication circuitry. The multimedia telephone still further includes a second module separable from the first module, coupled to the network interface and including a video input, connectible to the video camera, for receiving video information from the video camera, a video output, connectible to the television set, for transmitting other video information to the television set, and second module wireless communication circuitry coupled to the camera input and the television output and wirelessly couplable to the first module wireless communication circuitry. The first and second module wireless communication circuitry cooperate to establish a wireless communication link between the first and second modules. The multimedia telephone is embodied in the first and second modules to allow the first module to be separate from the second module and proximate the user.

Claims

1. For use with a video camera, a television set and a communications network capable of carrying voice and video data, a multimedia telephone, comprising:

a network interface for coupling said multimedia telephone to said communications network;

a first module, coupled to said network interface and including a user interface for communicating audio information with a user and first module wireless communication circuitry; and

a second module separable from said first module, coupled to said network interface and including (a) a video input, connectible to said video camera, for receiving video information from said video camera, (b) a video output, connectible to said television set, for transmitting video information to said television set, and (c) second module wireless communication circuitry coupled to said camera input and said television output and wirelessly couplable to said first module wireless communication circuitry, said first and second module wireless communication circuitry cooperating to establish a wireless communication link between said first and second modules, said multimedia telephone embodied in said first and second modules to allow said first module to be separate from said second module and proximate said user.

2. The multimedia telephone as recited in claim 1 wherein said network interface is associated with said first module and said wireless communication link is a wireless video communication link.

3. The multimedia telephone as recited in claim 1 further comprising:

a user interface for communicating audio information with said user, and

a key pad unit interface for receiving dialing information from said user.

4. The multimedia telephone as recited in claim 1 wherein one of said first and second module wireless communication circuitry includes audio/video coder/decoder (CODEC) circuitry.

5. The multimedia telephone as recited in claim 1 wherein said user interface comprises a handset.

6. The multimedia telephone as recited in claim 1 wherein said wireless communication link is a radio frequency (RF) link.

7. The multimedia telephone as recited in claim 1 wherein said video camera is contained in a chassis separate from said second module.

8. For use with a video camera, a television set and a communications network capable of carrying voice and video data, a method of operating a multimedia telephone, comprising the steps of:

coupling a network interface of said multimedia telephone to said communications network;

activating a first module, coupled to said network interface and including a user interface for communicating audio information with a user and first module wireless communication circuitry; and

establishing a wireless communications link with a second module separable from said first module, coupled to said network interface and including (a) a video input, connectible to said video camera, for receiving video information from said video camera, (b) a video output, connectible to said television set, for transmitting video information to said television set, and (c) second module wireless communication circuitry coupled to said camera input and said television output and wirelessly couplable to said first module wireless communication circuitry, said first and second module wireless communication circuitry cooperating to establish said wireless communication link between said first and second modules, said multimedia telephone embodied in said first and second modules to allow said first module to be separate from said second module and proximate said user.

9. The method as recited in claim 8 wherein said network interface is associated with said first module and said wireless communication link is a wireless video communication link.
