Internet radio is very similar to broadcast radio. It allows listeners to tune in to shows from their computer. Since it is streamed, listeners don’t need to download anything to access the broadcast. Instead, they log onto a particular web site to listen in. This form of communication is sometimes known as webcasting. It is not the same medium as podcasting, since a podcast must be downloaded to the listener’s computer or MP3 player before it can be listened to. The broadcast is sent out over the network and listeners will experience a lag time of up to 10 seconds depending on the server when listening to a broadcast. The lag time occurs because the data is sent out over a TCP/IP (Transmission Control Protocol/Internet Protocol) connection and then reassembled before the user can listen to it. Many Internet radio broadcasts are produced by existing broadcast stations that share their programming with Internet users. They may choose to offer a simulcast of the live broadcast or change
Internet radio is essentially the same as regularly broadcast radio, with a few distinguishing characteristics. Whereas there is a minimal lag time with regular radio because it broadcasts through the air, Internet radio has a lag time of 2.5 to 10 seconds or so, depending on the server. Internet radio is streamed, and so does not involve downloading. You simply log on to the particular site and in it comes.
