Abstract

A “reduced button count” remote control device controls a set of external electronic devices that, collectively, comprise an entertainment system such as a home theater. The remote control device is operable in conjunction with a processor-based subsystem that is programmable to respond to a spoken command phrase for selectively altering an operational state of one or more of the external electronic devices to cause the entertainment system to enter a given activity. The remote control device includes a set of buttons supported within a housing, the set of buttons consisting essentially of a push-to-talk button, a first subset of buttons dedicated to providing up and down volume and channel control, a second subset of buttons dedicated to providing motion control, and a third subset buttons dedicated to providing menu selection control. Preferably, each of the buttons has a fixed, given function irrespective of the particular command phrases or the given system activities. After the push-to-talk button is selected to engage the processor-based subsystem to recognize a spoken command phrase to cause the entertainment system to enter the activity mode, the first subset of buttons is used to provide any required up and down volume and channel control, the second subset of buttons is used to provide any required motion control, and the third subset of buttons is used to provide any required menu selection control.

Claims

1. In a control system for controlling a set of electronic devices that together comprise an entertainment system, the control system having a processor-based subsystem that is programmable to respond to a command phrase for selectively altering an operational state of one or more of the electronic devices, the improvement comprising:

a communications device in electronic communication with the subsystem and including a push to talk control mechanism;

a voice recognizer executable by the processor-based subsystem; and

code executable by the processor-based subsystem in response to actuation of the push to talk control mechanism (a) for generating a control code that mutes at least one audio source in the entertainment system, and (b) for enabling the voice recognizer to recognize at least one command phrase while the audio source is muted.

2. In the control system as described in claim 1, wherein the code executable by the processor-based subsystem also provides an indication of whether the command phrase can be acted upon given a presumed state of the one or more electronic devices.

3. In the control system as described in claim 1 wherein the communications device comprises a set of buttons supported within a housing, the set of buttons consisting essentially of up and down volume and channel buttons, motion control buttons, and menu control buttons.

4. In the control system as described in claim 1 further including a control code emitter responsive to the control code for muting the at least one audio source.

5. In the control system as described in claim 4 wherein the control code emitter is distinct from the processor-based subsystem to facilitate control over one or more of the electronic devices irrespective of their relative placement in the entertainment system.

6. In the control system as described in claim 1 wherein the code executable by the processor-based subsystem operates as a state machine to control the set of electronic devices.

7. In the control system as described in claim 1 wherein the code executable by the processor-based subsystem generates at least one control sequence based on a shadow state of one or more of the electronic devices.

8. In the control system as described in claim 1 wherein the code executable by the processor-based subsystem generates one or more control codes to establish a given activity associated with the electronic devices.

9. A remote control device for controlling a set of electronic devices that together comprise an entertainment system, the remote control device operable in conjunction with a processor-based subsystem that is programmable to respond to a spoken command phrase selected from a set of spoken command phrases, the response selectively altering an operational state of one or more of the given electronic devices, comprising:

a housing;

a mechanism supported within the housing that, upon activation, engages the processor-based subsystem to recognize a spoken command phrase in the set of spoken command phrases; and

input means consisting essentially of a set of manual input devices supported within the housing, wherein each device in the set has a given function that is substantially independent of any spoken command and that is not assignable through any other manual operation.

10. The remote control device as described in claim 9 wherein the set of manual input devices consists essentially of a first subset of buttons dedicated to providing a given set of first control actions, a second subset of buttons dedicated to providing a given set of second control actions, and a third subset buttons dedicated to providing a given set of third control actions.

11. The remote control device as described in claim 10 wherein the first subset of buttons consists essentially of volume and channel controls and the given set of first control actions consist essentially of up and down.

12. The remote control device as described in claim 10 wherein the second subset of buttons consists essentially of motion controls and the given set of second control actions consist essentially of play, rewind, fast forward, pause and replay.

13. The remote control device as described in claim 10 wherein the third subset of buttons consists essentially of menu selection controls and the given set of third control actions consist essentially of up, down, left, right and select.

14. The remote control device as described in claim 9 wherein the processor-based subsystem is supported within the housing.

15. The remote control device as described in claim 9 further including a microphone for receiving the spoken command phrase.

16. The remote control device as described in claim 9 wherein the mechanism is a push-to-talk mechanism.

17. A system for controlling a set of electronic devices that together comprise an entertainment system, comprising:

a remote control device comprising a housing, and a set of buttons, the set of buttons consisting essentially of a push-to-talk button, a first subset of non-programmable buttons dedicated to providing up and down volume and channel control, a second subset of non-programmable buttons dedicated to providing motion control, and a third subset non-programmable buttons dedicated to providing menu selection control;

a processor-based subsystem that is programmable to respond to a spoken command phrase for selectively altering an operational state of one or more of the electronic devices;

wherein, after the push-to-talk button of the remote control device is selected to engage the processor-based subsystem to recognize a spoken command phrase, the first subset of buttons is used to provide any required up and down volume and channel control, the second subset of buttons is used to provide any required motion control, and the third subset of buttons is used to provide any required menu selection control.

18. The system as described in claim 17 further including code executable by the processor-based subsystem in response to actuation of the push-to-talk button (a) for generating a control code that mutes at least one audio source in the entertainment system, and (b) for enabling a voice recognizer to recognize at least one spoken command phrase while the audio source is muted.

19. The system as described in claim 17, wherein the code executable by the processor-based subsystem also provides an indication of whether the spoken command phrase can be acted upon given a presumed state of the one or more electronic devices.
