Abstract:
1. A digital optical interface device comprising: a DVI or HDMI input interface configured to electrically connect to a DVI or HDMI receptacle of a digital source device to receive input TMDS electrical signals from the digital source device, the input interface comprising a serializer for serializing the TMDS signals into a electrical serialized signal and an optical transmitter configured to receive the electrical serialized signal and convert the electrical serialized signal to an input optical signal, the optical transmitter further configured to transmit the input optical signal to an input optical fiber; a coupler configured to couple the input optical signal with at least two optical output fibers coupled to the input optical fiber by the coupler; wherein each optical output fiber is coupled to a respective output interface, each output interface being configured to electrically connect to a different DVI or HDMI receptacle of two different digital sink devices, each output interface comprising an optical receiver configured to receive the input optical signal from a respective one of the at least two optical output fibers and convert the input optical signal to an output serialized electronic video signal that is received by respective deserializers of the respective output interface, each deserializer deserializing the respective output serialized electronic video signal back into the TMDS electrical signals that are suitable for use by a respective one of the DVI or HDMI digital sink devices, wherein the digital optical interface device is configured to communicate the same signals from the digital source device to at least two digital sink devices.
