Abstract
The remote control comprises: input circuitry and structure including a set of keys or pushbuttons for inputting commands to the remote control; infrared signal output circuitry for supplying an infrared signal to a controlled device including IR lamp driver circuitry; a central processing unit (CPU) coupled to the input circuitry and structure and to said signal output circuitry means; a memory coupled to the CPU; code data for generating infrared codes stored in the memory; and data coupling circuitry and structure coupled to the CPU for enabling at least one of instruction codes or of infrared code data for generating infrared codes to be supplied from outside the remote control through the data coupling circuitry and structure directly to the CPU for entry into the memory to enable a user of the remote control to operate a selected controlled device upon inputting commands to the remote control by depressing selected keys of the remote control.
