Broadcasting is the distribution of audio or video content to a dispersed audience via mass media, such as radio and television. It involves the transmission of signals to a vast number of receivers simultaneously.
Key Characteristics / Core Concepts
- One-to-many communication: A single source transmits information to many receivers.
- Mass reach: Broadcasting aims to reach a large, diverse audience.
- Public accessibility: Broadcast content is generally available to the public.
- Transmission medium: Signals are typically transmitted via radio waves or satellite.
- Regulation: Broadcasting is often subject to government regulation.
How It Works / Its Function
Broadcasting involves encoding audio or video content into a signal, which is then transmitted via a chosen medium (e.g., radio waves for terrestrial broadcasting or satellite for satellite broadcasting). Receivers—radios, televisions, or other devices—decode the signal to reproduce the original content. This process allows for simultaneous reception by a wide audience.
Examples
- A local radio station broadcasting a morning news program.
- A national television network airing a primetime drama.
- A satellite provider distributing television channels to subscribers.
