What is Streaming Media?
Streaming media is media that is consumed (read, heard, viewed) while it is being delivered. Streaming
is more a property of the delivery system than the media itself. The distinction is usually applied to media
that is distributed over computer networks; most other delivery systems are either inherently streaming
(radio, television, Internet TV) or inherently non-streaming (books, video cassettes, audio CDs).
Cisco Digital Media Encoder 2200 is designed specifically for streaming audio and video media over an
IP network.
