Abstract

A master device interactively distributes a television signal to a remote device for remote display with low latency between a user input and a television signal change.

Claims

1. A method, comprising:

receiving a plurality of media content in compressed format over a communication medium from a remote location at a master set-top box, the master set-top box operatively coupled to a wireless Ethernet device configured to provide a point coordination function (PCF) by allowing for defined periods of time for the master set-top box to broadcast;

providing a first graphics user interface (GUI), the first GUI comprising selectable entries corresponding to the plurality of media content; and

simultaneously communicating the plurality of media content in compressed format to a second client device, the second client device configured to provide a second GUI having selectable entries corresponding to those presented in the first GUI, wherein communicating the plurality of media content comprises communicating the plurality of media content in encrypted format;

receiving a control command from the second client device through a serial connection at the wireless Ethernet device, wherein the wireless Ethernet device is configured to forward the control command to the master set-top box; and

changing the media content in response to the control command.

2. The method of claim 1, wherein the communicating comprises communicating over a wireless link.

3. The method of claim 1, wherein communicating comprises communicating from a first room of a residence to a second room of the residence.

4. The method of claim 1, wherein receiving comprises receiving over a bidirectional communication medium.

5. The method of claim 1, wherein receiving comprises receiving by a tuner over a communications interface.

6. The method of claim 1, further comprising communicating the second GUI to the second client device.

7. The method of claim 1, further comprising communicating data to the second client device, the second GUI comprising the communicated data.

8. The method of claim 1, wherein the second client device comprises a set-top terminal.

9. The method of claim 1, wherein the second client device comprises a portable electronic device.

10. The method of claim 1, further comprising decoding the one or more content for presentation on a display device.

11. A system, comprising:

a second client device, the second client device comprising a second decoder; and

a first client device, configured as a master set-top box, communicatively coupled to the second client device, the first client device comprising a first decoder and a tuner, the tuner configured to receive a plurality of media content in compressed format from a headend over a communication medium, the first decoder configured to decompress the compressed plurality of media content for subsequent display, the first client operatively coupled to a wireless Ethernet device configured to provide a point coordination function (PCF) by allowing for defined periods of time for the master set-top box to broadcast;

wherein the first client device is further configured to;

provide a first graphics user interface (GUI), the first GUI comprising selectable entries corresponding to the plurality of media content; and

simultaneously communicate the plurality of media content in compressed format to the second client device, the second client device configured to provide a second GUI having selectable entries corresponding to those presented in the first GUI, wherein communicating the plurality of media content comprises communicating the plurality of media content in encrypted format;

receive a control command from the second client device through a serial connection at the wireless Ethernet device, wherein the wireless Ethernet device is configured to forward the control command to the first client device; and

change the media content in response to the control command.

12. The system of claim 11, further comprising a first display device and a second display device coupled respectively to the first and second client devices, the first display device configured to display the first GUI, the second display device configured to display the second GUI.

13. The system of claim 11, wherein the first display device and the second display device each comprise a television set.

14. The system of claim 11, wherein the first client device comprises a set-top terminal.

15. The system of claim 11, wherein the second client device comprises a set-top terminal.

16. The system of claim 11, wherein the second client device comprises a laptop computer with an integrated display.

17. The system of claim 11, wherein the second client device comprises a personal digital assistant.

18. The system of claim 11, wherein the second client device comprises a TV pad.

19. A set-top terminal, comprising:

a tuner configured to receive a plurality of media content in compressed format over a communication medium from a remote location;

a processor configured to;

provide a first graphics user interface (GUI), the first GUI comprising selectable entries corresponding to the plurality of media content; and

wirelessly simultaneously communicate the plurality of media content in compressed and encrypted format to a second client device, the second client device configured to provide a second GUI having selectable entries corresponding to those exactly presented in the first GUI;

wherein the set-top box is operatively coupled to a wireless Ethernet device configured to provide a point coordination function (PCF) by allowing for defined periods of time for the set-top box to broadcast;

wherein the wireless Ethernet device is configured to receive a control command from a second client device through a serial connection and forward the control command to the set-top box.
