Broadcast of Internet Radio
Distribution of Internet radio is largely dependent upon streaming technology which typically uses a 'lossy audio codec'. Formats for streaming audio include MP3, HE-AAC, RealAudio, Windows Media Audio, Ogg Vorbis and others. Continuous and serial transmission of audio data occurs over the local network or internet in UDP packets and TCP which are then reassembled at the receiver and are played moments later. This delay is termed as lag which is introduced in various stages of digital audio broadcasting.
