Cable TV

What is Cable TV?
Cable TV (CATV) stands for Cable Television, i.e., a method of providing consumers with access to television programs via coaxial cables or through optical fiber cable located in the subscribers’ premises.

How does it work?
TV Network companies beam their TV shows via satellites. Cable operators (or multi-system operators (MSO)) install head-ends (control centres for cable network) for aggregation of TV channels received from different satellites. They can mix this with content received from other sources such as broadband connections, local channels, etc., to form a bouquet of channels and then distribute to homes using coaxial cable (hence, the name cable TV) network installed either underground or hung over utility poles. To access the cable television services, one needs to subscribe to a cable company which will then connect a simple coaxial cable from the wall outlet to the television sets.
