Programmable appliance remote control
First Claim
1. A system for wirelessly activating an appliance, the appliance responding to one of a plurality of transmission schemes, the system comprising:
- a transmitter operative to transmit a radio frequency activation signal;
at least one user activation input, each activation input identifying a channel;
a programming input;
memory holding data describing a plurality of rolling code transmission schemes associated with a rolling code mode and a plurality of fixed code transmission schemes, at least one fixed code transmission scheme associated with each of at least one fixed code mode; and
control logic in communication with the transmitter, the at least one user activation input, the programming input and the memory, for each channel the control logic maintaining a channel mode set initially to a rolling code mode, the channel mode changing to one of the at least one fixed code mode if the channel is trained to a fixed code received from the programming input, the control logic in response to an assertion of the user activation input associated with the channel generating and transmitting an activation signal based on each transmission scheme associated with the mode maintained for the channel.

Abstract
A universal remote control is provided. For each channel supported, a mode is initially established as rolling mode. For a fixed code appliance, a fixed code is received and stored, and the mode changed to fixed mode. When an activation request is received, the mode associated with that activation input is examined. If the mode is rolling mode, a sequence of rolling code activation signals is transmitted, each based on one of the plurality of rolling code transmission schemes. If the mode is fixed mode, at least one activation signal is transmitted based on a fixed code transmission scheme and including the stored fixed code.

14. A method of controlling an appliance activated by a radio frequency activation signal described by a transmission scheme, the transmission scheme one of a plurality of possible transmission schemes including a plurality of rolling code transmission schemes and a plurality of fixed code transmission schemes, the method comprising:
-
establishing a mode as rolling mode;
if user input indicating a fixed code appliance is entered, receiving a fixed code from the user, storing the received fixed code and changing the mode to fixed mode;
receiving an activation request from a user;
if the mode is rolling mode, generating and transmitting a sequence of rolling code activation signals, each activation signal based on one of the plurality of rolling code transmission schemes; and
if the mode is fixed mode, generating and transmitting at least one activation signal, each of the at least one activation signal based on one of the plurality of fixed code transmission schemes, each of the at least one activation signal including the stored fixed code. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A method of activating a remotely controlled appliance, the appliance responding to an activation signal based on at least one of a plurality of activation schemes, the method comprising:
-
receiving an assertion of one of at least one activation input;
determining if the asserted activation input is associated with a programmed fixed code; and
if the asserted activation input is not associated with a programmed fixed code, transmitting a plurality of different rolling code activation signals each based on a different rolling code activation scheme. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31)
