    To give one channel to a cable network, you require 1 receiver. So if a cable network have 40 channels, 40 receivers are used.
    They use dual feed-horn to receive H & V pol. on same satellite.

    How did 40 channels run into single cable network? By means of cascading 40 recivers and assigned UHF/VHF for each reciever to feed the signal?

    Sorry for stupid questions but asking from expert is the best way to learn.

    Thank you.

    Thank you.
    As I have said 40 receivers are required, 40 modulators are also required.
    There are various "bands" in the cable line. For example:- Prime Band, X Band, Y band, Z band,S band etc.... Modulators are categorized using these bands. Each receiver is connected to a Modulator via AV cord. The output from modulator is given to "Channel Mixer". A ordinary channel mixer contains 18 ports. This means you can connect 18 modulators to a "channel mixer". You can raise the number of channel mixers as per the Channel numbers in the network. The output from "Channel Mixers" is given to a splitter. The output from that splitter contains all channels. In one word, the cable TV technology is based on Modulators.
    Hope you will understand this.

    Is there any other way or device to by-pass control of channels from the receiver and directly send all channels to Channel Mixer through RF connection? It means, no more control in the receiver using remote control, all channels send to Channel Mixer. If this is possible we need only 1 receiver.

    Sorry, I've never seen a mixer or modulators but just an idea if it possible then we can all be a cable TV provider

    Not yet Receiver companies are also not trying to do this bcoz if they do, the receiver demand will go down and cable operators will not buy 40 receivers to provide 40 channels. instead one is enough.

    It's not possible to give 16 channels on one screen to cable tv customers. If you do that, they will disconnect your service. :P
