Remote controller apparatus and an audio-video combination system using the same
First Claim
1. A combination of a first audio/video apparatus, a second audio/video apparatus and a remote control apparatus, wherein:
- said first audio/video apparatus has a first code output terminal;
said second audio/video apparatus has a second code output terminal and a third code input terminal;
said remote control apparatus comprises;
means for selectively establishing a learning mode and a conversion mode;
means for inputting second code signals directly from said second code output terminal of said second audio/video apparatus via a cable or an infrared signal sensing unit when in said learning mode;
means for inputting first code signals, representing respective command control functions, from said first code output terminal of said first audio/video apparatus controlled by another remote control device via a cable or an infrared signal sensing unit when in said conversion mode;
output means for outputting third code signals to said third code input terminal of said second audio/video apparatus via a cable or an infrared light-emitting unit;
lookup table memory means for storing said second code signals at respective memory locations corresponding to said command control functions controlled by the respective first code signals, so as to form a conversion table in said lookup table memory; and
microprocessor means for converting each of said first code signals into said respective third code signal by using said conversion table to locate said second code signal which corresponds to the command control function controlled by said first code signal and to supply said located second code signal as said third code signal from said output means.

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.
