Preface: About This Guide
2 ViewCast
The major difference between the two versions is that Niagara SCX Pro contains MPEG-4 encoding
technology and Niagara SCX Standard does not. Its basis remains anchored on an international
standard that is rapidly becoming the format of choice for streaming Internet video. Chapter 10 of
this publication more fully explains the MPEG-4 features, available only in Niagara SCX Pro. The
MPEG-4 implementation in SCX follows the guidelines of ISO/IEC 14496-2 specifications that
make the system compatible with the most popular third-party MPEG-4 implementations that use
the MPEG-4, Simple Profile and/or Advanced Simple Profile.
Audience
The audience for this guide includes anyone who uses or administers the Niagara SCX software.
They should have a basic technical understanding of their media-encoding environment and some
basic experience with streaming media principles and practices. They should also understand and use
Microsoft Windows.
