ABSTRACT:
A video signal provider multiplexes digital video signals for four channels and provides a signal the bandwidth of which is limited to 6 MHz by RF-modulation. An analog video signal provider provides another signal the bandwidth of which is limited to 6 MHz by RF-modulation. A digital audio signal provider multiplexes digital audio signals for 32 channels and provides another signal the bandwidth of which is limited to 6 MHz by RF-modulation. Such signals are combined and transmitted through a coaxial cable 14 to a controller. In this example, such signal providing apparatus can provide a maximum of 84 channels (=126 MHz (the bandwidth for video signal of the coaxial cable)/6 MHz.times.4 ch), which number is significantly larger than the 20 channels provided in the prior art.
