Transmitter, receiver and extender system

摘要

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.

主权项

1. A transmitter, comprising:
a signal input terminal for receiving a digital video-audio signal from a source, which comprises a plurality of digital differential signals and a plurality of single-end/low frequency signals; a plurality of first loading units for generating a plurality of first differential mixed signals, each first loading unit including a first multiplex filter for low-pass filtering one of the plurality of single-end/low frequency signals from the source and high-pass filtering one of the plurality of digital differential signals from the source and mixing the filtered single-end/low frequency signal and the filtered digital differential signal to obtain one of the plurality of first differential mixed signals, wherein the filtered single-end/low frequency signal and the filtered digital differential signal are superimposed onto each other and simultaneously present in the first differential mixed signal; and a communication port for outputting the first differential mixed signals.
