Cable TV starts at the antenna farm. The networks beam their programs via satellite to the local cable company, whereby the different feeds are received from different satellites. Then the feeds are modulated in 200 different channels with 600 MHz. The 200 channels are are then transmitted to a coaxial cable.
The TV signals then work their way down the cable to your house. The cable service provider uses an amplifier along the way in order to boost the signals.
How Channels are Broadcasted
Multiple television programs from all around the world are being broadcasted after they are produced. These programs are then transmitted to the satellites that orbit the earth. These signals are then transmitted back to earth and then transmitted by way of radio frequencies to televisions through coaxial cable or fixed optical fibers.
A cable TV doesn't need the traditional antenna to broadcast programs which, traditionally, were done via radio waves or over-the- air method.
The international programs along with the local signals from local television programs are then processed at the head-end or cable television service companies that provide the service. These signals are then transmitted into the homes of consumers through a network of cables.
How to Get Cable Service
One can subscribe from a cable television service provider to get a cable service to work.
The cable service providers will then ensure that the signals are transmitted through a coaxial cable to the cable outlet in your home. The cable company connects the coaxial cable or an RF cable from the wall directly to your television sets. Your cable ready television set can then be programmed to receive the cable channel broadcasts.
You would need to install a converter box if you own an older style or a non-cable ready TV set. This converter box will allow you to receive cable television broadcasts.
Advantages of Cable Television
