Patent ID: 7440702

Claim:
A method for communicating a digital image signal including a parallel digital image signal and a reference clock signal, the parallel digital image signal having at least corresponding image signals of RGB, the method comprising: with a transmitter of the digital image signal, generating a clock signal based on the reference clock signal, converting the parallel digital image signal into a serial digital image signal using the clock signal, and converting the serial digital image signal into an optical signal for transmitting; with a receiver of the digital image signal, receiving the optical signal from the transmitter, converting the received optical signal into a serial digital reception signal including electric signals, extracting a clock extraction signal corresponding to the clock signal from the serial digital reception signal, recovering the parallel digital image signal from the serial digital reception signal using the clock extraction signal, recovering the reference clock signal from the clock extraction signal, converting a receiver control signal including a control signal of at least one system of the receiver into a receiver control serial signal using the clock extraction signal, and converting the receiver control serial signal into a second optical signal for transmitting; with the transmitter, receiving the second optical signal from the receiver, converting the received second optical signal into the receiver control serial signal including electric signals, and recovering the receiver control signal from the receiver control serial signal using the clock signal.
