Abstract

A target device including a first tuner to output first signals from a first channel to an output device of the target device, a second tuner to selectively output second signals from a second channel to a remote control device, and an autonegotiation module to exchange data with the remote control device. The remote control device is configured to control the target device. The data exchanged with the remote control device relates to capabilities of at least one of the target device and the remote control device. The data includes at least one of an output resolution of the target device, a display size of the remote control device, a display resolution of the remote control device, and a processing power of the remote control device. The second tuner outputs the second signals to the remote control device based on the data exchanged with the remote control device.

Claims

1. A target device, comprising:

a first tuner configured to

tune to a first channel, and

output first signals from the first channel to an output device of the target device;

a second tuner configured to

tune to a second channel, and

selectively output second signals from the second channel to a remote control device,

wherein the remote control device is configured to control the target device; and

an autonegotiation module configured to

exchange data with the remote control device,

wherein the data relates to capabilities of at least one of (i) the target device and (ii) the remote control device,

wherein the data includes at least one of

an output resolution of the target device,

a display size of the remote control device, and

a display resolution of the remote control device, and

wherein the second tuner is configured to output the second signals to the remote control device based on the data exchanged with the remote control device.

2. The target device of claim 1, further comprising a control module configured to perform at least one of data reduction and data compression on the second signals prior to sending the second signals to the remote control device.

3. The target device of claim 1, further comprising a wireless interface configured to receive commands from the remote control device to adjust operation of the target device.

4. The target device of claim 1, further comprising:

a wireless interface configured to transmit streaming data to the remote control device,

wherein the streaming data include at least one of streaming video data and streaming audio data.

5. The target device of claim 1, further comprising a wireless interface configured to:

transmit voice over Internet protocol (VOIP) data to the remote control device, and

receive voice data from the remote control device.

6. The target device of claim 1, wherein at least one of the second signals includes at least one of:

a status information of the target device;

a channel guide; and

close captions.

7. The target device of claim 1, wherein the target device caches data at the remote control device.

8. The target device of claim 1, further comprising a user input interface configured to allow a user to adjust operation of the target device.

9. The target device of claim 1, wherein the data exchanged with the remote control device includes at least one of:

a memory size of the remote control device,

a cache size of the remote control device,

a function supported by the remote control device, and

a remote function supported by the target device.

10. A system comprising:

the target device of claim 1;

the remote control device; and

an access point configured to

receive commands to control the target device from the remote control device, and

transmit the commands received from the remote control device to the target device.

11. A method, comprising:

tuning to a first channel and a second channel;

outputting first signals from the first channel to an output device of a target device;

selectively outputting second signals from the second channel to a remote control device, wherein the remote control device is configured to control the target device;

exchanging data with the remote control device, wherein the data relates to capabilities of at least one of (i) the target device and (ii) the remote control device, wherein the data includes at least one of

an output resolution of the target device,

a display size of the remote control device, and

a display resolution of the remote control device; and

outputting the second signals to the remote control device based on the data exchanged with the remote control device.

12. The method of claim 11, further comprising performing at least one of data reduction and data compression on the second signals prior to sending the second signals to the remote control device.

13. The method of claim 11, further comprising receiving commands to adjust operation of the target device from the remote control device.

14. The method of claim 11, further comprising:

transmitting streaming data to the remote control device,

wherein the streaming data include at least one of streaming video data and streaming audio data.

15. The method of claim 11, further comprising:

transmitting voice over Internet protocol (VOIP) data from the target device to the remote control device, and

receiving voice data from the remote control device.

16. The method of claim 11, wherein at least one of the second signals includes at least one of:

a status information of the target device;

a channel guide; and

close captions.

17. The method of claim 11, further comprising caching data for the target device at the remote control device.

18. The method of claim 11, further comprising adjusting operation of the target device using a user input interface of the target device.

19. The method of claim 11, wherein the data exchanged with the remote control device includes at least one of:

a memory size of the remote control device,

a cache size of the remote control device,

a function supported by the remote control device, and

a remote function supported by the target device.

20. The method of claim 11, further comprising:

transmitting commands to control the target device from the remote control device to an access point, and

transmitting the commands from the access point to the target device.
