METHODS OF BROADCASTING


The first form of electronic broadcasting began with the advent of Théâtrophone ("Theatre Phone") system.

was a telephonic distribution system available in portions of Europe that allowed the subscribers to listen to opera and theatre performances over the telephone lines.

It was invented by Clément Ader (French inventor) in the year 1881 in Paris.

TELEPHONE BROADCAST


EVOLUTION OF TELEPHONE

2000-2016


Radio broadcasting is a unidirectional wireless transmission over radio waves intended to reach a wide audience.

Audio signals sent through the air as radio waves from a transmitter, picked up by an antenna and sent to a receiver.

Radio stations can be linked in radio networks to broadcast common radio programs, either in broadcast syndication, simulcast or sub-channels.

RADIO BROADCASTING


It is a telecommunication medium used for transmitting sound with moving images.

Television broadcast is a mass medium for entertainment, education, news, and advertising.

TELEVISION BROADCAST

EVOLUTION OF TV


Cable radio or cable FM is a concept similar to that of cable television (a system in which television programs are transmitted to the sets of subscribers by cable rather than by a broadcast signal.), bringing radio signals into homes and businesses via coaxial cable.

It is generally used as cable TV was in its early days when it was "community antenna television", to enhance the quality of terrestrial radio signals that are difficult to receive in an area. However, cable-only radio outlets also exist.

CABLE RADIO BROADCAST

A direct-broadcast satellite (DBS) is a type of artificial satellite which usually broadcasts satellite television signals for home reception.

The signals are received via an outdoor parabolic reflector antenna usually referred to as a satellite dish and a low-noise block downconverter (LNB - is the receiving device mounted on satellite dishes used for satellite TV reception, which collects the radio waves from the dish.)

A satellite receiver then decodes the desired television program for viewing on a television set.
