Ok I'm going to ask this plain and simple "how does cable television get into my tv"?

Question

where does it start (the source)?

and all the in between until it goes to my cables and into my T.V.

Answer 1

It starts at your local cable company.  Drive by there and take a look at the sattelite dishes all around the place.

Then it runs over the cable wires to your house.  Pretty simple.

Answer 2

the people in Hollywood send signals out by satalite to your local cable company then the signals is sent by cable to your house with the help of little tiny nano bots pushing the signal down the cable line
