How Does Internet Radio Work

We turn on the radio and we instantly hear talk or music. Terrestrial broadcasting is very different than broadcasting on the internet. The audio is sent to the transmitter and is sent over the air where anyone in the signal area can pick it up. The drawback

is a limited reception area.

Internet Radio transmission is different. Here's how it basically works.

  1. The audio enters the Internet broadcaster’s encoding computer through a sound card.

  2. The encoder system translates the audio from the sound card into streaming format. The encoder samples the incoming audio and compresses the information so it can be sent over the Internet.

  3. The compressed audio is sent to the server, which has a high bandwidth connection to the Internet.

  4. The server sends the audio data stream over the Internet to the player software or plug-in on the listener’s computer. The plug-in translates the audio data stream from the server and translates it into the sound heard by the listener.

There are really no limitations. The broadcast can be heard where there is internet access. We will be discussing some complications that can occur with this process in coming blogs.
