Abstract
An apparatus for remotely controlling audio/video devices from different manufacturers. First code signals are directly input to the remote controller apparatus when it is in a learning mode by way of a cable or an infrared light-emitting unit from a peripheral audio/video device. The first code signals are stored in specified locations of a conversion table in the lookup table memory. Second code signals are input to the remote controller apparatus when it is in a conversion mode from another audio/video apparatus by way of a cable or an infrared light-emitting unit. The second code signals represent command control functions. The conversion of the second code signals to third control signals is accomplished by a microprocessor using the conversion table containing the first code signals. The third code signals are output from the remote controller apparatus to control a peripheral audio/video device. Also, there is disclosed an audio/video combination system using the remote controller apparatus.
