Digigami Ships MPressionist HDTV 3.0: Testing and Analysis for HDV, ATSC HDTV, DVB and HD-DVD MPEG-2 Video
Posted Jun 30, 2005 Print Version     Page 1of 1

Digigami today announced it is now shipping MPressionist HDTV 3.0 for Macintosh OS X (BSD unix-based) workstations, its flagship diagnostic testing and analysis tool for HDV/DTV/DVB device designers, and quality assurance, broadcast, and software engineers working with standard (SD) and high-definition (HD) MPEG-2 bitstreams.

The product, in it's third major revision, combines bitstream syntax analysis, bitstream standards conformance, encoder performance feedback, statistical bitrate/compression diagnostics and comparative picture analysis tools into an environment designed to increase engineering productivity by linking the engineer's technical expertise and MPEG knowhow with the bitstream syntax and actual moving picture frames. The toolset, which combines a demultiplexing/analysis preprocessing pass with true random access to the bitstream, makes it possible to understand and visualize all aspects of compressed MPEG-2 video, including the spatial/visual, statistical and syntatical elements.

First developed as an internal tool to bootstrap HD encoder development at Digigami, since it's initial public 1.0 release the feature set has grown to encompass a wider variety of testing and diagnostic activities. The product is now in use in codec development, quality assurance, compression service bureaus and post-production facilities, educational and training institions, and broadcast environments.

Built on top of the industrial-strength BSD unix platform of Macintosh OS X, the product works in conjunction with other tools customers have already developed in-house. Because the underlying OS is unix-based, the engineer has access to all the standard unix tools that are commonly used in the professional/engineering workplace. The ability to run on Macintosh hardware also means HD engineers can connect one or more 30" Apple Cinema displays and work with multiple 1920x1080i MPEG-2 HD bitstreams simultaneously.

When dealing with a complex problem space such as HD MPEG-2, the ability of an operator to increase their own knowledge of the domain depends almost exclusively on comparative analysis. It is by objective comparison, and through the identification of key and useful differences, that one's own knowledge expands. Whether it's comparing the statistical bitrate graph of two bitstreams, comparing the relative sizes of I,B and P-frames, comparing gop_header values, comparing source video quality to compressed MPEG quality, or comparing well-formed bitstreams with problematic ones, MPressionist HDTV provides both the visualization tools which lead to intuitive leaps along with the factual bitstream data that is driving the display. Problems are resolved sooner, reducing time-to-market, decreasing support costs, and increasing the productivity of key design and engineering personnel.

The new 3.0 version of Digigami "MPressionist HDTV" is available now for $2997.00 USD. Registered users of version 2.0 are entitled to a free upgrade. Site licenses, educational and volume discounts are available. Digigami is a privately held company headquartered in the greater Los Angeles area. Digigami was founded in 1994 and released its first MPEG-1/MPEG-2 encoder, MegaPEG, in 1996 along with an early Netscape plug-in that provided streaming video in AVI, QuickTime and MPEG formats. For the past 10 years, Digigami has been continuously improving its MPEG compression technology; MPressionist.X Pro HD and MegaPEG.X Pro HD are the most recent additions to the Digigami line.
