We are pleased to make available another release of NVR's digital media
development kit, version 2.0.3.  You should already have a license key.
If you don't, please contact us at support@nvr.com.


This version has several fixes for bugs and some important improvements
over version 2.0.2.  In particular:
   - Support added for Alias PIX files
   - Support added for playing XING sequences that have illegal syntax
     (extra picture info and non-increasing temporal references)
   - 400% speed improvement for RGB --> Y/Cr/Cb conversion in the compressor
     and imageop (you'll want this if you are compressing any rgb files,
     such as SGI rgb files).
   - the deinterlace operator (in imageop and the compressor) was broken
     in version 2.0.2.  You would only notice this if you are compressing
     abekas or other interlaced files.

The 2.0.x version is a significant improvement over our last major release,
1.0.4.  Briefly, this software offers:
   - MPEG video compression
   - image processing and compatibility with many image file formats,
     including JPEG, TIFF, SGI RGB and others.
   - MPEG audio compression
   - compatibility with a variety of audio files, including AIFF, AIFC
     Sun Audio and Parallax movie files.
   - MPEG system multiplexing
   - real-time, synchronized playback of any combination of video and audio
     files.   This means you can play back MPEG video files with AIFF, or
     you can play back MPEG system streams containing MPEG video and
     MPEG audio.  And everything in between
   - a variety of tools for converting image file formats and audio file
     formats.
   - a real-time video/audio recording program (Sun and Parallax hardware
     required)

The software package is available in several pieces via anonymous ftp to

URL=ftp://nvr.com/pub/NVR-software/
    [192.82.231.50]

Look in /pub/NVR-software for the license 
agreement and README file.  It also contains about 25 megabytes of data and 
software, so first fetch the README file and read it to decide what you 
need.  If you only need the software, you should get one of

    SGI-Product-2.0.3.tar.Z
    Sun-Product-2.0.3.tar.Z

depending on the kind of hardware you have.
