Abstract
Methods and apparatus are provided for generating codes for controlling appliances from a remote controller. One method includes the steps of entering a compressed pointer for accessing a stored protocol and for accessing stored key data corresponding to appliance command keys on the remote controller, decompressing the entered pointer, and storing the decompressed pointer, entering a compressed protocol for generating codes for controlling an appliance, the protocol comprising a pattern fragment for a zero and a one, a zero timing, a one timing, and a carrier frequency, decompressing the entered protocol, storing the decompressed protocol, entering compressed key data, the key data corresponding to appliance command keys on the remote controller, decompressing the entered key data, storing the decompressed key data, accessing the protocol and the key data using the pointer, and generating a code using the pattern fragment for a zero and a one, the zero timing, the one timing, the carrier frequency, and the key data.
