Definition
Television (TV) is a mass advertising medium which combines moving images and sound. [1]
The signal may be transmitted in a number of ways (terrestrial, cable, satellite, or internet) and is ultimately received by a television set. [1]
Broadcast television (or terrestrial television) is a method of distributing television signals by means of stations that broadcast signals over channels assigned to specific geographic areas. [1]
Cable television is a method of distributing television signals by means of coaxial or fiber-optic cables. Cable subscribers can receive a wide variety of cable television channels, and some cable systems enable subscribers to both receive and send information by means of the cable connection between the cable system office and individual households. Cable television services may also include telephone and internet connection capabilities. [1]
Satellite television is a particular kind of broadcast delivery based on using space satellites to deliver signals. Companies make use of satellites that have been sent out of the Earth’s atmosphere by beaming a signal up to the satellite and delivering it to individual customers via the use of receiving equipment.
