Internet Radio Broadcast - Basic glossary

Other Articles Available

------------- -------------

We have been receiving a big amount of e-mails and phone calls asking for advice on setting, configuring, programing and promoting internet radio stations, therefore, we had decided to write a series of articles about this interesting and not well documented subject, in order to familiarize our users with tools and services currently available that are used to broadcast Internet Radio, or simply, to help enthusiastic beginers to develop their own online radio stations.

While the concept of transmission of radio and television on the Internet is relatively new, this has become a popular choice for both radio producers as for the general public

There are many different scenarios in which broadcasting traditional radio stations on Internet is an invaluable service to loyal listeners and, at the same time, it helps the station to increase the number of listeners, that allows them to explore new sources of income, in many cases international, by reaching audiences only available to radio stations with bigger coverage area or short wave broadcasting.

One of the reasons that led us to built this website, develop our software (world TVRT) and has been serving us as motivational propelling during the last years of hard work and research is the need for migrants to keep in touch with their native countries, if we have in mind that the number of migrants could reach several hundred of millions worldwide, we can, easily deduct that the posibilities offered by this new comunication concept are countless.

I have mentioned just one group of potential beneficiaries of this technology, but there are many more uses such as languages students or journalist, etc

I believe that the best way to understand this subject begins with some basic concepts about related terms used by internet broadcasters therefore I start this guides with a small glossary (but it will grow each time that we add a new chapter to our guide)... Let's begin...

  • Internet Radio or e-Radio : is an audio broadcasting service transmitted via the Internet

  • Webcast is a live media file distributed over the Internet using streaming media technology. In other words, webcasting is the transmission of linear audio or video content over the Internet. using a technology knows as "streaming media" that allows to take a single content source and distribute it to many simultaneous listeners or viewers

  • Simulcast: fusion of two words "simultaneous broadcast", refers to programs or events broadcast across more than one medium, or more than one service on the same medium, at the same time, in our case it refers to traditional radio stations and television channels that broadcast their signals over Internet.

  • Broadcasting: is the distribution of audio or video signals to an audience.

  • Streaming Media: is media that uses multiple forms of information content (e.g. audio, animation, video, interactivity) to inform or entertain audience and that is continuously received and displayed by the end-user while it is being delivered by the broadcaster (provider).

  • Poadcast: is a digital media file, or a series of such files, that is distributed over the Internet using syndication feeds for playback on portable media players and personal computers. In other words a poadcast is a specific type of webcast which, can mean either the content itself or the method by which it is syndicated.

  • Streaming: One of the most common ways to distribute internet radio is via streaming technology using a lossy (low loss) audio codec. Some popular formats are MP3, Ogg, Vorbis, Windows Media Audio (WMA) and Real Audio.

The definitions and explanations about stream speed, number of users, simultaneous conections, file format, etc, will be explained in detail the first time that they are mentioned in our guide, in this way we can expalin them using practical examples
