Abstract

Impulse radio links are applied as the wireless means for allowing the separation of traditionally wired audio/video displays from their sources of information. This wireless separation affords an enhanced information system architecture in which a remote user interface can select from a variety of information and/or entertainment sources. The data bandwidth and superior performance of impulse radios in a high RF multipath environment open these previously hardwired interfaces to a wireless implementation. For example, untethered television is provided.

Claims

1. (canceled)

2. A system, comprising

a tuner adapted to receive a signal;

a video display physically separate from the tuner;

a first UWB transceiver;

a second UWB transceiver coupled to the video display and operable to receive a signal to therby drive the video display; and

a third UWB transceiver, coupled to the tuner, operable to determine the position of the second UWB transceiver based on the first UWB transceiver and the second UWB transceiver, and transmit the signal to the second transceiver based on the position of the second UWB transceiver.

3. The system of claim 2, wherein the third UWB transceiver is operable to transmit the signal as a time-modulated ultra-wideband impulse signal.

4. The system of claim 2, wherein the third UWB transceiver is further operable to transmit the signal to the second UWB transceiver based on an identity of the second UWB transceiver.

5. The system of claim 4, wherein the third UWB transceiver determines the identity of the second UWB transceiver using a key.

6. The system of claim 2, wherein the signal is compressed by the third UWB transceiver and decompressed by the second UWB transceiver.

7. A method, comprising

receiving a signal at a tuner;

determining the position of a first UWB transceiver based on a second UWB transceiver and a third UWB transceiver;

transmitting the signal to the first UWB transceiver based on the position of the first UWB transceiver;

receiving the signal at the first UWB receiver; and

driving a video display physically separate from the tuner using the signal.

8. The method of claim 7, wherein the signal is transmitted as a time-modulated ultra-wideband impulse signal.

9. The method of claim 7, wherein the signal is transmitted to the first UWB transceiver based on an identity of the first UWB transceiver.

10. The method of claim 9, further comprising determining the identity of the first UWB transceiver using a key.

11. The method of claim 7, further comprising compressing the signal and decompressing the signal.
