Abstract
A transmitter includes a signal input terminal, multiple loading units and a communication port. The signal input terminal receives a digital video-audio signal, which comprises multiple digital differential signals and multiple single-end/low frequency signals. The loading units respectively load the corresponding single-end/low frequency signals to the digital differential signals to obtain multiple differential mixed signals. A frequency of the digital differential signals is higher than a frequency of the corresponding single-end/low frequency signals. The communication port outputs the differential mixed signals to a receiver via a network cable.
Claims20
A transmitter, comprising:
- a signal input terminal for receiving a digital video-audio signal, which comprises a plurality of digital differential signals and a plurality of single-end/low frequency signals;
- a plurality of loading units, each loading unit for mixing one of the plurality of single-end/low frequency signals and one of the plurality of digital differential signals to obtain a plurality of differential mixed signals;
- and
- a communication port for outputting the differential mixed signals.
A receiver, comprising:
- a communication port for receiving a plurality of differential mixed signals;
- a plurality of separating units, each separating unit for separating one of the plurality of differential mixed signals into a digital differential signal and a corresponding single-end/low frequency signal;
- and
- a signal output terminal for outputting the digital differential signals and the single-end/low frequency signals as a digital video-audio signal.
A signal extender system, comprising:
- a transmitter for receiving a digital video-audio signal comprising a plurality of digital differential signals and a plurality of single-end/low frequency signals and respectively mixing the plurality of single-end/low frequency signals and the plurality of digital differential signals so as to form a plurality of differential mixed signals;
- and
- a receiver, coupled to the transmitter via a network cable, for receiving the differential mixed signals via the network cable, and separating the differential mixed signals into the plurality of digital differential signals and the plurality of single-end/low frequency signals to obtain and output the digital video-audio signal.
