Abstract:
1. A digital signage system, comprising: a transmitting device adapted for coupling to one end of a cable, the cable including a first, a second, a third and a fourth pair of differential transmission lines, the transmitting device receiving a video signal, transforming the video signal to a first, a second, and a third pair of differential signals, and transmitting the first, second, and third pair of differential signals to the first, second, and third pair of differential transmission lines, respectively; and a receiving device adapted for coupling to another end of the cable, for receiving the first, second, and third pair of differential signals from the first, second, and third pair of differential transmission lines of the cable, and transforming the first, second, and third pair of differential signals to the video signal, wherein the receiving device receives a remote-captured video signal, generates a processed remote-captured video signal which contains the remote-captured video signal, and transmits the processed remote-captured video signal to the transmitting device via the fourth pair of differential transmission lines of the cable.
