In choosing the right streaming format for your needs, you should first consider the audience for
your content. What common player will they use to watch your content? This determines the
format of the stream you create for your audience.
To determine the data rate you need for streaming your content; you must determine the IP
bandwidth for your audience access.
For example, if the access method uses an ISDN connection or less, then you stream your video
and/or audio at a low data rate such as QCIF at 56 kbps. If your audience has faster and more
reliable access, like a cable modem or DSL connection, then you can provide a higher quality
stream at full resolution at 2 Mbps.
Niagara encoders provide preconfigured encoding profiles for different bandwidth connections.
The profiles loaded depend on how you configure your Niagara encoder on its initial startup.
