Las Vegas� April 21, 2006 � Plano-based ViewCast Corporation today announced the introduction of NiagaraSCX 5.0, the latest version of its remote control and monitoring software application for Osprey�-based encoders.

NiagaraSCX 5.0 software incorporates digital rights management (DRM) for Windows Media�, MPEG-4 /H.264 and MPEG-2 encoding standards. The software will be bundled with the Niagara streaming systems and is planned to ship in May 2006.

�NiagaraSCX 5.0 offers a tremendous set of tools and capabilities for broadcasters managing a �farm� of multiple streaming encoders, allowing them to simultaneously view multiple encoders on multiple machines,� said Dave Stoner, president and COO of ViewCast. �With multiple access methods � NiagaraSCX 5.0 explorer and XML programming � the software affords greater flexibility and control of encoding parameters like encoding profile, bit rate, capture resolution, capture attributes, preprocessing options and authored information. Users can view and set encoding parameters, start and stop the encoding process and receive notification of identified error conditions with a remote control.�

NiagaraSCX allows users to capture broadcasts live, store them to a file and convert MPEG or analog video content to streaming format. The software is meant to benefit those looking for control without compromising on flexibility while managing a large number of encoders.

In addition to Microsoft�s� Windows Media & RealNetworks� players, the H.264-capable software can be played on the Apple� QuickTime� player.
