Abstract

An image display system capable of displaying two distinct images at the same time. One image is shown on an image display device such as a television or computer monitor which is coupled to the image display system. The other image is shown on a remote control included in an image display system. A docking station is also part of the image display system. It is connected by standard audio-visual coaxial cable to the TV and associated video devices and sends compressed digital video signal information to the video remote control by RF communication. Both the docking station and the video remote control have RF antennas and receivers capable of sending digital RF signals. Digital command and information signals are exchanged between the docking station and video remote control to allow control from the remote control of the functions of the TV and other video devices. The remote control has a learning mode with onscreen feedback making the image display system backward and forward compatible with a wide array of image display devices. The invention is thought to be particularly useful for networked computer televisions.

Claims

2. The remote control system of claim 1 wherein said remote control is a learning remote control.

3. The remote control system of claim 1 wherein said image display device includes said transmitter.

4. The remote control system of claim 1 wherein said image display device does not include said transmitter.

5. The remote control system of claim 1 further comprising at least one image source for outputting said second image signal to said transmitter.

6. The remote control system of claim 1 further comprising:

a controller for selecting said second image signal from a plurality of image signals.

7. The remote control system of claim 6 wherein said controller is responsive to a control signal from the remote control.

8. An image display system capable of displaying two distinct images, said image display system comprising:

a first image source for outputting a first image signal;

a second image source for outputting a second image signal;

a first controller coupled to said first and second image sources for selecting a first selected image signal and a second selected image signal from said first and second image signals;

a image display for displaying a first image corresponding to said first selected image signal chosen from said first image signal and said second image signal;

a first transmitter for transmitting said second selected image signal;

a video remote control (VRC) including;

a VRC receiver for receiving said second selected image signal transmitted by said first transmitter;

a VRC image screen for displaying a VRC image corresponding to said second selected image signal;

a VRC controller for producing control signals based upon inputs by a user; and

a VRC transmitter for transmitting said control signals;

wherein said first controller is responsive to said control signals, and

said first image on said image display and said VRC image on said VRC image screen may be distinct.

9. The image display system of claim 8 further comprising a image device that includes said first image source.

10. The image display system of claim 9 wherein said image device is a television.

11. The image display system of claim 9 wherein said image device is a VCR.

12. The image display system of claim 8 wherein said first image source is a computer network.

13. The image display system of claim 8 wherein said first image source also receives a first audio signal associated with said first image signal.

14. The image display system of claim 8 wherein said first transmitter and said VRC receiver operate in a frequency range between approximately 5.15 GHz and 5.85 GHz.

15. The image display system of claim 8 wherein said first transmitter and said VRC receiver operate in a wavelength range between approximately 0.8 μ

m and 1.2 μ

m.

16. The image display system of claim 8 wherein said image screen displays input options of said VRC controller corresponding to said control signals for selection by said user.

17. The image display system of claim 16 wherein said VRC image screen is touch sensitive such that said input options can be selected by said user by touching portions of said VRC image screen.

18. The image display system of claim 16 wherein said display of said input options on said VRC image screen is a soft key display.

19. The image display system of claim 8 further comprising a docking station including said first transmitter.

20. The image display system of claim 19 wherein the docking station further includes said second image source.

21. A learning remote control comprising:

a receiver for receiving an original command signal sent by an original remote control, wherein the signal corresponds to an original command of said original remote control;

a memory coupled to said receiver for storing said original command signal;

circuitry for associating the original command signal with a desired command; and

a feedback mechanism for indicating whether said original signal has been successfully saved in said memory for association with the desired command,

wherein the feedback mechanism includes a display device for displaying information relating to the storage of the command signals.

22. The learning remote control of claim 21 wherein the display device of the feedback mechanism displays a first label for said desired command.
