Chapter 32. Streaming Multimedia > Streaming Media Concepts

Streaming Media Concepts

Streaming technology is an attempt to avoid the eternal bandwidth problem. In 1994, RealAudio introduced a way of delivering Internet audio based on the User Datagram Protocol (UDP) rather than the usual Transmission Control Protocol (TCP). UDP technology was later used for transferring video files as well.

UDP technology does not require confirmation of the receipt of all the data; instead, it delivers the file as quickly as possible. This means that a user can begin playing the audio or video file even before the whole file is received. The user's wait time is cut dramatically. Over time, Real has expanded its line of products and services to include a range of enhanced services to bring streaming media to the Web.
