Abstract

A programmable, universal remote control for controlling many different of remote controlled devices, such as televisions, videocassette recorders, and cable boxes is provided. The remote control can be programmed with a code corresponding to a particular manufacturer and model of the remote controlled device to be controlled. The remote control can also display this code on the remote controlled device using preexisting circuitry in the remote control. If the user does not know the particular manufacturer/model code corresponding to the remote controlled device to be controlled, he may sequence through the available manufacturer/model codes in the remote control until an appropriate code is found. Methods are also provided for programming, displaying, and searching for the appropriate manufacturer/model code in the remote control.

Claims

1. A method of displaying a device code on a remote controlled device, the device code being representative of the remote controlled device, the method comprising the steps of:

initiating a display mode in a remote control;

retrieving the device code, the device code being stored in the remote control;

transmitting a program code, the program code being transmitted from the remote control, the program code being representative of the device code; and

changing the remote controlled device to a first state which is displayed in response to receiving the program code, the first state being representative of the device code, the first state being indicative of the device code to a user.

2. A method of displaying information representative of a manufacturer/model code on a remote controlled device as defined by claim 1, wherein the step of initiating the program mode includes the step of selecting at least one button on the remote control.

3. A remote control, the remote control having a display mode, the remote control comprising:

a processing circuit;

a memory device, the memory device being responsive to the processing circuit, the memory device having a device code stored therein, the device code being representative of a remote controlled device, the processing circuit retrieving the device code from the memory device in response to the remote control being in the display mode, the processing circuit generating a program code, the program code being representative of the device code; and

a transmitter, the transmitter being responsive to the processing circuit, the transmitter transmitting the program code to the remote controlled device, the remote controlled device being in a first state which is displayed in response to receiving the program code, the first state being representative of the device code, the first state being indicative of the device code to a user.

4. A remote control as defined by claim 3, wherein the processing circuit includes at least one of a microcontroller, microprocessor, application specific integrated circuit (ASIC), and programmable logic device.

5. A remote control as defined by claim 3, wherein the remote controlled device is a television, the television being able to be tuned to at least one of a plurality of channels, the first state being representative of at least one of the plurality of channels to which the television is tuned.

6. A remote control as defined by claim 3, further including at least one button, wherein the display mode is initiated by selecting the at least one button.

7. A remote control as defined by claim 3, further including at least one button, wherein the program mode is terminated by selecting the at least once button.

8. A remote control as defined by claim 3, wherein the transmitter includes an infrared (IR), light-emitting diode (LED).
