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 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).
The Cisco Digital Media Encoder 2000 is designed specifically for streaming audio and video media
over an IP network.

Streaming Infrastructure

Before setting up your new Cisco Digital Media Encoder 2000, it is useful to understand the
complete overview of live streaming video – from video capture to streaming video playback.
There are many applications for capturing video into the computer environment that can range from
DVD authoring to live Web casting. Regardless of the final use of the video, all can be categorized
into three main workflow processes:
• Single video/session capture (i.e. one-off file capture for non-real time delivery)
o Typically the captured file is then processed and/or authored into its final form for
delivery
• Batch video/session capture (i.e. archiving, scheduling and storage)
o Multiple source content is to be digitalized
o Device control is needed for unattended source
o Ability to schedule sessions is needed to capture timed events
• Live video capture, processing and delivery (Web casting)
o Can be single or multiple sources
o Live event at a specific time
o Can be a remote or local capture
o Final content is delivered in real time to viewers
Each category has its unique set of requirements that also dictates different user interfaces,
functionality and experiences. The Cisco Digital Media Encoder 2000 is designed for live video
capture, processing and delivery.
Below is a diagram illustrating the video path starting with the source, like a camera or video player,
going through the Cisco Digital Media Encoder 2000, to the server, across an IP network, to a
software player and displayed on a monitor for audience viewing.
