  • 1.  
  • 2. Internet radio?
    • Internet radio  (also  web radio ,  net radio ,  streaming radio ,  e-radio   webcasting ) is an audio service transmitted via the Internet. Internet radio involves streaming media presenting listeners with a continuous stream of audio that cannot be paused or replayed, much like traditional broadcast media; in this respect, it is distinct from on-demand file serving.
  • 3. How it is different from podcasting?
    • Internet radio is also distinct from podcasting which involves downloading rather than streaming. Many Internet radio services are associated with a corresponding traditional (terrestrial) radio station.
    • Internet radio services are usually accessible from anywhere in the world—for example, one could listen to an Australian station from Europe. Some major networks restrict listening to in country because of music licensing and advertising concerns
  • 4. Advantages
    • Traditional radio station broadcasts are limited by two factors:
    • 1. the power of the station’s transmitter (typically 100 miles)
    • 2. the available broadcast spectrum (you might get a couple of dozen radio stations locally)
  • 5. Advantages
    • Internet radio has  no geographic limitations , The potential for Internet radio is as vast as cyberspace itself.
    • Internet radio is  not limited to audio . An Internet radio broadcast can be accompanied by photos or graphics, text and links, as well as interactivity, such as message boards and chat rooms. This advancement allows a listener to do more than listen.
  • 6. Advantages
    • The cost of getting “on the air” is less  for an Internet broadcaster.
    • Internet radio can  appeal to “micro-communities” of listeners focused on special music or interests .
  • 7. Disadvantage
    •   Since all of these radio stations are visited by listeners looking for free music or entertainment, they do not necessarily contribute to the revenues of the station. Barring a few successful Internet radio stations, no one has had considerable success with advertising generated revenues
    • Internet Crashes
  • 8. How it works????
    • There are two ways to deliver audio over the Internet: downloads or streaming media. In  downloads , an audio file is stored on the user’s computer. Compressed formats like  MP3  are the most popular form of audio downloads, but any type of audio file can be delivered through a Web or FTP site.  Streaming audio  is not stored, but only played. 
  • 9. How it works?????
    • The audio enters the Internet broadcaster’s encoding computer through a sound card.
    • 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.
    • The compressed audio is sent to the server, which has a high bandwidth connection to the Internet.
    • 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.
  • 10. Creating an Internet Radio Station
    • CD player
    • Ripper software (copies audio tracks from a CD onto a computer’s hard drive)
    • Assorted recording and editing software
    • Microphones
    • Audio mixer
    • Outboard audio gear (equalizer, compressor, etc.)
    • Digital audio card
    • Dedicated computer with encoder software
    • Streaming media server
  • 11. Scenario in India
    • Internationally, many of the offline radio players have understood the power of this medium and have live or recorded Internet streaming available. In India, with its numerous music copyright regulations and issues, this phenomenon has not been duplicated. Some radio stations, though, have put up the clippings of their programmes on the Internet for free download.
