Abstract:
An electronic device comprising:a) a single infra-red receiver circuit for receiving infra-red energy emitted from remote units and for generating data signals responsive thereto;b) a single external single-pin bus coupled to said infra-red receiver circuit for propagating said data signals; andc) an integrated circuit coupled to said single external single-pin bus for decoding said data signals for an intelligent controller circuit, said integrated circuit comprising:an internal bus coupled to said single external single-pin bus;a keyboard interface coupled to said internal bus to receive said data signals and to identify keyboard data signals, wherein said keyboard interface decodes said keyboard data signals into keyboard control signals for said intelligent controller circuit;a mouse interface coupled to said internal bus to receive said data signals and to identify mouse data signals, wherein said mouse interface decodes said mouse data signals into mouse control signals for said intelligent controller circuit; anda remote-control interface circuit coupled to said internal bus to receive said data signals and to identify remote-control data signals, wherein said remote-control interface circuit decodes said remote-control data signals into remote-control control signals for said intelligent controller circuit.
