First Internet Radio Standards Released

September 16, 2009


Using IBC 2009 as a backdrop, the Internet Media Device Alliance (IMDA) unveiled a first-ever "baseline" certification standard set for dedicated Internet radio appliances at Sept. 7 press event.

Identified simply as IMDA Profile 1, the baseline standards identify the following characteristics as essential in all Internet Radio Appliances:

  • Decoding for both WMA and MP3 codecs
  • HTTP streaming with 301 and 302 redirection
  • M3U, ASX and PLS playlist compatibility, with new line separation for URLs in plain text
  • Stereo stream decoding from two streams or mix of two streams

    John Ousby, an IMDA steering committee member and director of broadcaster services for Vtuner called the move an important step for continued rapid growth in online radio.

    An IFA press release describes the standards as essential in reducing time to market for manufacturers while reducing uncertainty among consumers about short-term obsolescence of individual purchases. The organization says it expects products sporting a new certification logo to begin appearing in retail outlets in time for the 2009 Christmas shopping season.
