Abstract
A learning type IR function code transmitter includes a memory storing the IR function codes of a large variety of different brands of transmitters. The learning transmitter includes an IR receiver and a microprocessor for detecting IR function codes transmitted from a teaching transmitter. The memory is searched when an on/off IR function code is required from the teaching transmitter. If a match is found between the received IR function code and one of the stored IR function codes, and if a unique set of IR function codes corresponding to the identified brand of teaching transmitter IR function codes exists, the transmitter keyboard is configured to operate with the function codes that correspond to the teaching transmitter. Provision is made for teaching one or more certain IR function codes to selected keys of the learning transmitter where such certain IR function codes are not found in the memory.
