Abstract

A universal multimedia access apparatus for accessing any of a plurality of multimedia applications provided by a multimedia network. The universal multimedia access apparatus accesses a predetermined one of the plurality of multimedia applications using an application-specific module interfaced thereto, the application-specific module being selected from a plurality of application-specific modules. The universal multimedia access apparatus comprises a transceiver and a processing unit. The transceiver communicates multimedia information between the multimedia network and the application-specific module, and communicates with the multimedia network in any one of a plurality of communication modes. The processing unit is operative to identify the application-specific module interfaced thereto and the predetermined one of the plurality of multimedia applications associated with the application-specific module, and operative to command the transceiver to communicate with the multimedia network in a mode associated with the predetermined one of the plurality of multimedia applications.

Claims

1. A universal multimedia access apparatus for use with multimedia applications provided by a multimedia network, the universal multimedia access apparatus comprising:

a first application specific module including a first interface and a second interface associated with an application specific device, the first application specific module associated with a first multimedia application;

an application independent module detachedly coupled to the first application specific module via the first interface, the application independent module comprising;

a transceiver to communicate multimedia information between the multimedia network and the first application-specific module; and

a processing unit in communication with the transceiver and the first application-specific module, the processing unit operative to identify the first application-specific module and the first multimedia application associated with the first application-specific module after the first application specific module is coupled to the application independent module, and operative to command the transceiver to communicate with the multimedia network in a mode associated with the first multimedia application.

2. The universal multimedia access apparatus of claim 1 wherein the first application-specific module includes an application-specific transceiver for communicating the multimedia information with the application specific device and wherein the application independent module is connected to a second application specific module.

3. The universal multimedia access apparatus of claim 1 wherein the multimedia information includes at least one of audio signals, image signals, data signals, and control signals.

4. The universal multimedia access apparatus of claim 1 wherein the first application-specific module comprises a telephone application-specific module and the application specific device comprises a telephone.

5. The universal multimedia access apparatus of claim 1 wherein the first application-specific module includes a data application-specific module and the application specific device comprises a computer.

6. The universal multimedia access apparatus of claim 1 wherein the first and a second application-specific module includes an image application-specific module and the application specific device is selected from the group consisting essentially of a camera, a video playback device, a video recording device, and a video display device the application specific device communicating image signals with the multimedia network.

7. The universal multimedia access apparatus of claim 1 wherein the first application-specific module includes a control application-specific module for communicating control signals with the multimedia network.

8. The universal multimedia access apparatus of claim 1 wherein the first and a second application-specific module are different applications selected from the group that includes a telephone application-specific module which interfaces with a telephone for providing a phone service via the multimedia network, a data application-specific module which interfaces with a computer for communicating data with the multimedia network, an image application-specific module which interfaces with at least one of a camera, a video playback device, a video recording device, and a video display device for communicating image signals with the multimedia network, and a control application-specific module for communicating control signals with the multimedia network.

9. The universal multimedia access apparatus of claim 1 wherein the first application specific module is in wireless communication with a second application specific device.

10. The universal multimedia access apparatus of claim 1 wherein the processing unit includes a microprocessor and a plurality of memory devices coupled thereto by a data and control bus, the plurality of memory devices including a read-only memory for storing an operating program and utilities accessed by the microprocessor, a random-access memory for storing session data, and an electrically erasable programmable read-only memory for storing data over a plurality of sessions.

11. The universal multimedia access apparatus of claim 10 wherein the first application-specific module is interfaced thereto via the data and control bus.

12. The universal multimedia access apparatus of claim 1 wherein the transceiver includes a wireless modem for communicating the multimedia information with the multimedia network.

13. The universal multimedia access apparatus of claim 1 wherein the transceiver includes a radio frequency cable modem for communicating the multimedia information with the multimedia network.

14. A multimedia system comprising:

a first universal multimedia access device comprising a first application specific module, a first application independent module, a first application specific transceiver and a second application specific transceiver, the universal multimedia access device in communication with a multimedia network;

a first application device in communication with the universal multimedia access device, the universal multimedia access device communicating with the first application device via the first application specific transceiver; and

a second application device in remote communication with the universal multimedia access device, the first universal multimedia access device communicating with the second application device via the second application specific transceiver.

15. The multimedia system of claim 14 wherein the second application specific transceiver comprises a video transmitter.

16. The multimedia system of claim 15 wherein the second application specific transceiver is in communication with the multimedia network.

17. The multimedia system of claim 15 wherein the video transmitter and the video receiver communicate over frequencies selected by a frequency reuse pattern.

18. The multimedia system of claim 16 further comprising a second universal multimedia device in communication with the multimedia network.

19. The multimedia system of claim 14, further comprising a second universal multimedia device in communication with the multimedia network.

20. The multimedia system of claim 19 further comprising a third application device in communication with the second universal multimedia access device.
