After signal source+adjacent frequency modulator to mixer, for example, 32 channels, 32 signal sources +32 adjacent frequency modulators (with different frequencies) +4 eight-port mixers. After mixing, a 4 cm output is connected to the cable TV signal amplifier and then distributed to each floor. If there are many rooms on each floor, you can add another signal amplifier on each floor and then distribute it to each room through power distribution. Ordinary closed-circuit front-end has a limit on the number of channels, and it is best not to exceed 40 or 50 channels, otherwise there will be interference between channels.
