Patent ID: 7738792

Claim:
A receiver, comprising: a single infrared (IR) sensor, which is coupled to sense an IR signal carrying data and to produce an electrical signal responsively to the IR signal; and multiple receiver channels arranged to accept the electrical signal from the single IR sensor, each receiver channel configured to process the electrical signal in accordance with a different, respective IR remote control protocol so as to extract the data, and to output the extracted data to a host system; wherein at least one of the receiver channels comprises a run-length port circuit, which is arranged to format the data carried by the electrical signal in a run-length format and to output the data in the run-length format to the host system; and wherein the host system has active and sleep operational states, wherein the run-length port circuit is disabled when the host system is in the sleep operational state, and wherein the at least one of the receiver channels further comprises a wake-up port circuit, which is arranged to monitor the electrical signal and, when detecting that the electrical signal conforms to the respective IR remote control protocol, to activate the run-length port circuit.
