Welcome to Niagara SCX
The exclusive ViewCast Niagara SCX streaming media management software supports Adaptive
encoding for Adobe® and Apple® HTTP (live streaming to iPhones® and iPads®), Adobe Flash®
H.264, H.264, H.263, MPEG-4 and Windows Media® (Silverlight™ compatible) SD and HD. It
provides an optimal method for managing live video broadcasting over the Internet and to
mobile devices. It allows you to set up, monitor, and control remote or distributed Niagara SCX
streaming encoder systems positioned throughout your enterprise or anywhere in the world –
all from your desktop. Niagara SCX is included on all ViewCast encoding appliances.
At the heart of Niagara SCX 6.2 is the new “iPhone Live Media Publisher” component, which
includes built-in MPEG-2 Transport Stream file segmenting and HTTP-based upload capabilities.
The “iPhone Live Media Publisher” multiplexes encoded audio and video packets into multiple
GOP-aligned, simultaneously output, and MPEG-2 Transport Stream (M2TS) files. AAC audio
encoder and H.264 video encoder configuration is easy with profiles included in Niagara SCX 6.2.
The M2TS files, along with their associated manifest files, are uploaded to major Content
Delivery Networks (CDNs) using CDN-specific authentication. Content protection is available via
built-in AES-128 encryption.
This manual focuses on the Niagara SCX client interface. For information on the web interface,
