Abstract

A remote control for communicating commands to a target device having first data that specifies a function supported by the target device. The remote control includes a set of command key indicias, stored within the universal remote control prior to any communications with the target device, each command key indicia being assigned a function identifier. The remote control is adapted to receive the first data from the target device and select a command key indicia from the set of command key indicias that has a function identifier that corresponds to the function specified by the first data. The selected command key indicia is displayable on a display of the universal remote control in association with a command key actuatable to communicate one or more commands to the target device to control the function supported by the target device that is represented by the first data.

Claims

1. A control unit configurable to control one or more functions of a target device, comprising:

a memory in which is stored a plurality of protocols and a plurality of commands;

a plurality of function keys; and

programming responsive to an input for selecting from the plurality of protocols stored in the memory a protocol that is appropriate for communicating with the target device, for transmitting to the target device using the selected protocol a request for configuration information, for receiving from the target device a function indicator transmitted by the target device in response to the transmitted request, for selecting from the plurality of commands stored in the memory a command appropriate for the target device and corresponding to the received function indicator, and for mapping the selected command to a select function key of the plurality of function keys such that activation of the selected function key results in communication of the selected command using the selected protocol to the target device to thereby control a function supported by the target device that is represented by the function indicator.

2. The control unit of claim 1, comprising a display wherein the plurality of function keys are displayed within the display.

3. The control unit of claim 1, wherein the function indicator groups related available functions under a single designator and wherein the programming selects from the plurality of commands a plurality of commands appropriate for the target device and corresponding to the received function indicator and maps each of the selected plurality of commands to a select function key of the plurality of function keys such that activation of a one of the selected function keys results in communication of a one of the selected plurality of commands using the selected protocol to the target device to thereby control a function supported by the target device that is represented by the function indicator.

4. The control unit of claim 1, wherein the function indicator is transmitted to the control unit utilizing an extension of the infrared transmission protocol.

5. A control unit configurable to control one or more functions of a target device, comprising:

a memory; and

programming responsive to an input for transmitting to the target device a request for configuration information, for receiving from the target device a set of function indicators transmitted by the target device in response to the transmitted request, for utilizing the function indicators received from the target device to configure the control unit, and for storing the resulting configuration in the memory for subsequent use in controlling one or more functions of the target device;

wherein at least one of the function indicators corresponds to at least one function to be controlled from a list of controllable functions recognizable by the programming and at least one of the function indicators comprises a code for indicating to the programming that data following the code is a definition of a new infrared code and a corresponding key annotation to which the new infrared code is to be mapped as a part of the resulting configuration.
