Abstract

A universal remote control unit for controlling the operation of a plurality of devices such as a cable box, a television, a video device, and an audio device, includes a processor having a plurality of operating modes, a first mode push button for initiating a mode change, and a plurality of second mode push buttons corresponding respectively to a plurality of devices for enabling a user to select one of the plurality of operating modes. The processor is operable in a selected one of the plurality of operating modes, upon activation of one of the second mode push buttons within a predetermined amount of time of activation of the first mode push buttons. The universal remote control unit is effective to reduce the likelihood of unintentionally changing the operating mode. In addition, the universal remote control unit may also be effective to readily allow a user to readily determine the current operating mode of the universal remote control unit by pressing the first mode push button, and selectively turn on/of the devices using the second mode push buttons.

12. A system for receiving cable television, the system comprising:

a cable box; and

a universal remote control unit of claim 1 for remote control of said cable box.

13. A method for operating a universal remote control unit having a plurality of operating modes for remotely controlling a plurality of devices, each of the plurality of operating modes corresponding to a different one of the plurality of devices, the method comprising:

providing a first mode means and a plurality of second mode means for enabling a user to select the plurality of operating modes; and

operating the universal remote control unit in one of the plurality of operating modes upon activation of one of the second mode means within a predetermined amount of time of activation of the first mode means.

14. The method of claim 13 further comprising controlling transmission from a transmitter to turn on/off at least one of the plurality of devices upon activation of at least one of the plurality of second mode means.

15. The method of claim 13 further comprising controlling transmission from a transmitter to turn on/off at least one of the plurality of devices upon activation of at least one of the plurality of second mode means after the predetermined time.

16. The method of claim 13 further comprising controlling transmission from a transmitter in response to a user-preprogramed selection of a plurality of functions of controlling the devices upon activation of one of the second mode means.

17. The method of claim 13 wherein the first mode means and the plurality of second mode means comprise a plurality of push buttons.

18. The method of claim 13 further comprising indicating a current operating mode upon activation the first mode means.

19. The method of claim 18 wherein the indicating a current operating mode comprises the second mode means comprising a plurality of illuminable push buttons.

20. The method of claim 18 wherein the indicating a current operating mode comprises illuminating one of the plurality of illuminable push buttons for the predetermined amount of time upon activation of the first mode means.

21.
