Abstract

In a home system in which a TV receives video from various sources over directional wireless links such as 60 GHz links, a mirror apparatus is provided that can be configured to physically steer a signal toward a receiver on the TV to optimize received signal strength. In this way, RF energy that otherwise would be radiated in non-productive directions away from the receiver is reflected toward the receiver.

Claims

1. Apparatus comprising:

TV chassis;

TV display supported on the chassis;

TV tuner receiving video signals;

TV processor communicating with the tuner and display to cause the video signals from the tuner to be presented on the display;

wireless data receiver receiving wireless video signals from a network; and

reflector assembly positioned to redirect, to the wireless data receiver, wireless video signals that otherwise would be at least partially blocked from the wireless data receiver by the chassis.

2. Apparatus of claim 1, wherein the reflector assembly is supported on the chassis in line of sight with the wireless data receiver.

3. Apparatus of claim 1, wherein the wireless data receiver does not communicate with the TV tuner.

4. Apparatus of claim 1, wherein the reflector assembly is movable on the chassis.

5. Apparatus of claim 1, wherein a control processor controls position of the reflector assembly.

6. Apparatus of claim 5, wherein the control processor controls position of the reflector assembly to establish an index of adequate signal at the receiver at least to satisfy a threshold, the index of adequate signal being communicated on a backchannel different than a main channel over which the wireless video signals are transmitted.

7. Apparatus of claim 5, wherein the control processor is established by one or more of the TV processor, and processor associated with the wireless data receiver on a transmitter sending information to the TV.

8. Apparatus of claim 1, wherein the reflector assembly is established by a microelectromechanical systems (MEMS) assembly comprising at least a digital micromirror device (DMD).

9. Device, comprising:

video display;

antenna receiving directional wireless signals;

processor receiving the signals for presentation on the display; and

mirror assembly reflecting the signals toward the antenna.

10. The device of claim 9, further comprising:

a TV chassis, the display being a TV display supported on the chassis;

a TV tuner receiving video signals;

a TV processor communicating with the tuner and display to cause the video signals from the tuner to be presented on the display; and

the antenna being implemented in a wireless data receiver receiving the directional wireless signals from a component.

11. The device of claim 10, wherein the mirror assembly is supported on the chassis in line of sight with the wireless data receiver.

12. The device of claim 9, wherein the mirror assembly is movable.

13. The device of claim 9, wherein a control processor controls position of the mirror assembly.

14. The device of claim 13, wherein the control processor controls position of the mirror assembly to establish an index of adequate signal at the receiver at least to satisfy a threshold.

15. The device of claim 13, wherein the control processor is established by one or more of a TV processor, and a processor associated with the antenna.

16. The device of claim 9, wherein the mirror assembly is established by a digital micromirror device (DMD).

17. A system in which a TV receives video over a directional wireless 60 GHz link, in which a mirror apparatus is provided that can be configured to physically steer a signal toward a receiver on the TV to optimize received signal strength, RF energy that otherwise would be radiated in non-productive directions away from the receiver being reflected toward the receiver.

18. The system of claim 17, wherein the mirror apparatus is established by a digital micromirror device (DMD).

19. The system of claim 18, wherein the DMD is mounted on a rear edge of a chassis of the TV.

20. The system of claim 17, wherein a control processor controls position of the mirror apparatus to establish an index of adequate signal at a receiver associated with the TV at least to satisfy a threshold, the index of adequate signal being sent on a link different from a link over which the video is sent.
