3. Internet Radio Programs  Internet Radio = Alternative Radio  Wide range of styles to meet a wide range of audience types  News, Music, Graphics from all over the world available across the net  Finding a Niche  Appealing to a target audience for increased capital or market share  Many cyber stations offer specific programming in order to do this  Internet Radio = Alternative Radio  Wide range of styles to meet a wide range of audience types  News, Music, Graphics from all over the world available across the net  Finding a Niche  Appealing to a target audience for increased capital or market share  Many cyber stations offer specific programming in order to do this

4. Internet Radio Programs, Continued…  Web-Only Radio: Networks and Stations  Many internet radio stations exist only on the web  Cost Comparison:  Cyberstation vs. Conventional Over-the-Air Station  $10K vs. > $250K  Other than cost, why?  No legal licensing or insurance requirements  The internet is totally unregulated and as such internet radio is unsanctioned by government rule  Web-Only Radio: Networks and Stations  Many internet radio stations exist only on the web  Cost Comparison:  Cyberstation vs. Conventional Over-the-Air Station  $10K vs. > $250K  Other than cost, why?  No legal licensing or insurance requirements  The internet is totally unregulated and as such internet radio is unsanctioned by government rule

5. CyberMusic  Audio-on-Demand  Transforms the internet into a music marketing Mecca  Most major record labels support and influence the use of the internet as a major source for “free” music to the public  Great marketing tool  Studies show record sales climb exponentially when certain clips are pre-released on the Web.  Audio-on-Demand  Transforms the internet into a music marketing Mecca  Most major record labels support and influence the use of the internet as a major source for “free” music to the public  Great marketing tool  Studies show record sales climb exponentially when certain clips are pre-released on the Web.

6. Internet Radio and the FCC  Big Brother’s listening, but not touching  The FCC has not stipulated any licensing requirements for web radio  Truly uncensored  Complete freedom for both artists and producers  This could change, though.  Big Brother’s listening, but not touching  The FCC has not stipulated any licensing requirements for web radio  Truly uncensored  Complete freedom for both artists and producers  This could change, though.

7. Internet Radio and the FCC, Continued…  The music industry and RealAudio influence on the net.  With increasing speed and accuracy, combined with streaming technology, the music industry is concerned about piracy.  Streaming technology is such that no file is ever copied, so music files are “temporary.”  There are ways to copy files “permanently,” but come on...you cant have your cake and eat it too...  Music Industry benefits from making audio available online  The music industry and RealAudio influence on the net.  With increasing speed and accuracy, combined with streaming technology, the music industry is concerned about piracy.  Streaming technology is such that no file is ever copied, so music files are “temporary.”  There are ways to copy files “permanently,” but come on...you cant have your cake and eat it too...  Music Industry benefits from making audio available online

8.  Internet Radio is not, like its counterpart, subject to ownership restrictions  FCC regulates how many over-air stations can be owned by any one company…not so for Web Radio.  Internet Radio is much less restrictive when compared with broadcast radio.  You want to start a web radio station, start one:  No One Cares...  Internet Radio is not, like its counterpart, subject to ownership restrictions  FCC regulates how many over-air stations can be owned by any one company…not so for Web Radio.  Internet Radio is much less restrictive when compared with broadcast radio.  You want to start a web radio station, start one:  No One Cares...

9. Producing an Internet Radio Show  Internet Radio vs.. Broadcast Radio  Both can be produced similarly, but with one fundamental difference: Digitizing  Digitizing: The process of converting analog files into 1s and 0s in a digital file format.  Encoding: storing a digital file in several different formats, depending on the need for the digital output.  Internet Radio vs..

10.  Encoding methods:  Two basic types...  Use dedicated Hardware, called an Encoder.  Limited functionality of resource (computer).  Use any computer with a Sound Card and appropriate software for file conversion  Encoding compresses large files so that memory allocation is considerably smaller than normal, allowing for ease of transfer over the network, and lessening download times.  Encoding methods:  Two basic types...  Use dedicated Hardware, called an Encoder.  Limited functionality of resource (computer).  Use any computer with a Sound Card and appropriate software for file conversion  Encoding compresses large files so that memory allocation is considerably smaller than normal, allowing for ease of transfer over the network, and lessening download times.

11.  Internet Radio Signal Path  Original file (analog/digital)  Digitizing  Encoding  File transfer  Server storage  Replication server  Providing mulitfeeds  IP Multicasting  Signal replication which occurs on the Internet  Internet Radio Signal Path  Original file (analog/digital)  Digitizing  Encoding  File transfer  Server storage  Replication server  Providing mulitfeeds  IP Multicasting  Signal replication which occurs on the Internet Producing an Internet Radio Show, Continued…

12.  File Transfer  Downloading  Storing a file in a digital format on a client computer for multiple usage  audio.wav  Streaming  Files are used in “real-time” but not stored digitally on the client computer  The server sends digital data in a continuous “loop” until the client disengages it’s connection  Uses Encoding and Reading technologies  File Transfer  Downloading  Storing a file in a digital format on a client computer for multiple usage  audio.wav  Streaming  Files are used in “real-time” but not stored digitally on the client computer  The server sends digital data in a continuous “loop” until the client disengages it’s connection  Uses Encoding and Reading technologies Producing an Internet Radio Show, Continued…

13.  Program Delivery  Internet radio delivers live radio through streaming technology  Production process of Internet Radio and Broadcast Radio are virtually the same, with two exceptions:  Mode of delivery  Signal processing  Program Delivery  Internet radio delivers live radio through streaming technology  Production process of Internet Radio and Broadcast Radio are virtually the same, with two exceptions:  Mode of delivery  Signal processing Producing an Internet Radio Show, Continued…

17. What the future brings...  Internet Radio is easy to set up, maintain, and program.  It’s likely that there will be more Internet Radio “stations” than Broadcast Radio stations in the near future  Internet Radio is easy to set up, maintain, and program.  It’s likely that there will be more Internet Radio “stations” than Broadcast Radio stations in the near future

18. What the future brings, Continued…  The many aspects of Internet Audio  Web Radio is just one.  Corporate Information Systems  Web Kiosks (virtual news stands)  Inter-geographical training sites  Long-distance education centers  UH Pioneering in Web Courseware  With increasing technology, Internet Radio is aiding the transformation of cyberspace into a “multimedia social environment.”  The many aspects of Internet Audio  Web Radio is just one.  Corporate Information Systems  Web Kiosks (virtual news stands)  Inter-geographical training sites  Long-distance education centers  UH Pioneering in Web Courseware  With increasing technology, Internet Radio is aiding the transformation of cyberspace into a “multimedia social environment.”
