Abstract
Systems and methods for optical transmission of one-or-more out-of-band signals associated with audio-video signal communication are described. In one aspect, an optical receiver receives a first out-of-band electrical signal and a second out-of-band electrical signal from a video sink. The first out-of-band electrical signal may correspond to an audio-video stream previously received or concurrently being received from a video source optical transmitter at the optical receiver. The second out-of-band electrical signal may also correspond to the audio-video stream. The optical receiver may combine the first out-of-band electrical signal and the second out-of-band electrical signal into a transmit electrical signal. In one aspect, the optical receiver converts the transmit electrical signal into an optical signal, and transmits the optical signal to an optical transmitter via an optical communication channel.
