Each category has its unique set of requirements that also dictate different user interfaces,
functionality and experiences. The Niagara encoders deliver live video capture, processing, and
delivery.
Figure 106 illustrates the video path starting with the source, like a camera or video player. This
source goes through the Niagara encoders, to the server, across an IP network, to a software
player and displays on a monitor for audience viewing.

Guide to Streaming Audio and Video Types
Niagara encoders can create several different types of audio and video streams. Although all are
a type of IP video format, each retains properties to make it more suitable to a specific
streaming video application. Niagara encoders create video content in a reduced resolution. This
allows users to stream the content across the Internet and play it back on a computer or a
handheld mobile device.
Figure 107 lists all formats supported by Niagara encoders with suggested application uses. You
can use all of these formats for many different applications.
