Remote control code search method and apparatus
First Claim
1. A remote control apparatus, comprising:
- a signal transmitter;
data entry means for allowing a user to enter data and commands, including one of a plurality of code search commands;
a memory circuit; and
a controller operatively coupled to said signal transmitter, said data entry means, and said memory circuit, said controller causing said signal transmitter to transmit a sequence of remote control signals during a code search mode of operation, said controller storing in said memory circuit an identification information associated with a most recently transmitted signal format in response to user entry of a code search stop command (STOP), wherein said controller causes said signal transmitter to transmit one of a plurality of sets of remote control signals in response to user entry of a first code search command (PLAY), each of said sets of remote control signals comprising a plurality of remote control signals, each one of said remote control signals in each of said sets being associated with a respective one of a plurality of signal formats stored in said memory circuit.

Abstract
A universal remote control and a method for programming a universal remote control allows a user to quickly and easily identify a set of remote control signal formats that include a desired signal format and then individually test the signal formats in the identified set to identify the desired signal format. A reference code, or other identification information, associated with the desired signal format. In the code search mode of operation, the present universal remote control generates and transmits one of a plurality of sets of signal formats stored in a memory circuit (RAM,ROM) in response to the user pressing a first control key (76). The user repeatedly presses the first control key and observes the controlled device to identify a set of signal formats that includes the desired signal format. After the desired set of signal formats is identified, the user presses either a second or a third control key (74,78) to individually transmit each signal format in the identified set of signal formats. The user repeatedly presses the second and third control keys and observes the controlled device to identify the desired signal format.

7. The method for programming a
remote control apparatus to control one of a plurality of devices, comprising the steps of: -
transmitting a sequence of remote control signals to a device to be controlled in response to user entry of a first code search command (PLAY) during a code search mode of operation, the sequence of remote control signals adapted to provide an observable response to a user;
storing the identification information associated with a most recently transmitted signal format in response to user entry of a code search stop command; and
generating and transmitting remote control signals in accordance with the identification information to control the device, wherein the transmitting step comprises transmitting one of a plurality of sets of remote control signals to the signal transmitter in response to user entry of a first code search command, each of the sets of remote control signals comprising a plurality of remote control signals, each of the remote control signals in each of the sets being associated with a respective one of a plurality of signal formats stored in a memory circuit of a remote control apparatus. - View Dependent Claims (8, 9, 10)
