Dynamic linking of codesets in universal remote control devices
View Patent ↗A codeset having function-code combinations is provisioned on a controlling device to control functions of an intended target device. Input is provided to the controlling device which designates a function to be controlled on the intended target device. From a plurality of codes that are each associated with the designated function in a database stored in a memory of the controlling device a first code that is determined to be valid for use in controlling the designated function on the intended target device is selected. When the codeset is then provisioned on the controlling device, the provisioned codeset includes as a function-code combination thereof the designated function and the first code.
1. A method for using a controlling device to command a functional operation of a controlled device, the method, comprising:
storing in a data structure within a memory of the controlling device first information that functions to link a first preset codeset stored in the memory of the controlling device with a second preset codeset stored in the memory of the controlling device and second information that functions to specify which one of the first preset codeset and the second preset codeset is to be accessed to retrieve therefrom a key code for use in generating a command for transmission to the controlled device in response to an activation of an input element of the controlling device whereby, in response to the input element of the controlling device being activated, the controlling device uses the first information and the second information to cause the controlling device to access one of the first preset codeset and the second preset codeset, to retrieve from the accessed one of the first preset codeset and the second preset codeset a key code corresponding to the activated input element, and to use the key code retrieved from the accessed one of the first preset codeset and the second preset codeset to generate the command for transmission to the controlled device.
2. The method as recited in claim 1 , wherein the second information comprises a flagbyte.
3. The method as recited in claim 1 , wherein the first preset code set and the second preset codeset are intended for use in commanding functional operations of the controlled device of a same type and brand.
4. The method as recited in claim 1 , wherein the first preset codeset and the second preset codeset are intended for use in commanding functional operations of the controlled device of a different type.
5. The method as recited in claim 1 , wherein input received while in a setup mode of operation of the controlling device is used to populate the data structure with the first information and the second information.
6. The method as recited in claim 1 , wherein the retrieved key code retrieved from the accessed one of the first preset codeset and the second preset codeset is used to generate the command for transmission to the controlled device via use of an infrared transmitter of the controlling device.
7. The method as recited in claim 1 , wherein the retrieved key code retrieved from the accessed one of the first preset codeset and the second preset codeset is used to generate the command for transmission to the controlled device via use of a radio frequency transmitter of the controlling device.
8. The method as recited in claim 1 , wherein the second information is automatically determined by the controlling device.
9. The method as recited in claim 1 , wherein an auto-scan program is executed by the controlling device to assist in populating the data structure with the first information and the second information.
