In the days when most people had dial-upInternet connections (where you make a connection to your InternetService Provider using a modem to enable what is essentially just a normal telephone call), slow speeds were amajor limitation on what could be done online. If you wanted to listen toan MP3 music track(typically about 5 megabytes in size), you could spend half an hourwaiting for the entire file to download onto your hard drive, then openit up and play it back. Video files (more likely to be 50 megabytes)would take several hours to download this way, so they were notgenerally available on the Net. In those days, it was impossible tolisten to a music or movie file of any size without a long and tediouswait. The problem was essentially a matter of bandwidth: the speed ofan Internet connection (how quickly it can download information) setsa limit to how quickly you can transfer a file.

Photo: Streaming media as it used to be. This is an early version of RealPlayer (the program thatkick-started the streaming media revolution) playing here over a 56 Kbpsdial-up Internet connection. The status bar at the bottom shows the radio station is beingplayed at 44.1 Kbps (over 44,000 binary digits per second), which is wellwithin the limits of the connection. The trick with streaming media is for the player toadapt to the limits of your Internet connection to avoid excessive buffering.Although modern fiber broadband connections have about 1000 times the bandwidth of dialup, buffering can still be an issue because people download much bigger files (HD movies) these days.
Most Internet radio stations use either this kind of adaptive (HTTP) streaming or older-style(RTP) streaming, where programs are downloaded and played simultaneously in your web browser,with a dedicated app, or with a program like RealPlayer, Apple's QuickTime, or the Microsoft Windows Media Player. With a decent broadband connection, you can enjoy audio quality that's not far off the quality you get from a downloadedMP3 sound file (though, as we discuss in our article on MP3, that's never quite as good as you'd get from a CD). As Internet connections have become faster, and more people have broadband, it's become possible to watch videos and TV programs this way too, though unless you stream in high definition over a really fast broadband line, quality is still short of what you'd get from watching TV or a DVD. That'sone reason why online movie stories still sometimes use downloads instead of streaming. 2ff7e9595c
