Simple guide to streaming audio and video types
As noted above, the encoder can create several different types of audio and video streams.
Although all are a type of IP video format, each has certain properties that make it more attuned
to a specific streaming video application.
The following chart lists all formats available on ViewCast Niagara encoders. All of these formats
can be used for many different applications.

To determine the data rate you will stream your content, you will need to determine the IP
bandwidth to which your audience has access.
For example, if the access method uses an ISDN connection or less, then you would stream your
video and/or audio at a low data rate such as QCIF at 56kbps. If the access is much greater like a
cable modem or DSL connection, then you can provide a higher quality stream at full resolution
at 2 Mbps. All Niagara encoders provide preconfigured encoding profiles for different bandwidth
connections. The profiles loaded will depend upon how you configure your Niagara encoder on
its initial startup.
