Abstract
Digital electronic devices for optical communication of digital video and/or audio signals between a digital source device and a digital sink device. A digital source device includes a transition minimized differential signaling (TMDS) transmitter for receiving control and digital video signals from a source controller and for converting the control and digital video signals into electric TMDS signals. An interface receives a first end of an optical fiber. An optical transmitter converts the electric TMDS signals to at least one optical signal and transmits the at least one optical signal to the first end of the optical fiber. A digital sink device receives the at least one optical signal from a second end of the optical fiber and converts the optical signal into TMDS signals. A TMDS receiver converts the TMDS signals into control and digital video signals and transmits the control and digital video signals to the sink controller.
