NVIDIA and InterVideo Deliver WHQL Certified Software DVD Playback for RIVA TNT


WinDVD's Breakthrough User Interface Combined with Leading Graphics Technology Delivers Consumer-Quality Software DVD Solution to Mainstream
SANTA CLARA, CA – APRIL 29, 1999 – NVIDIATM Corporation (NASDAQ: NVDA) and InterVideo, Inc. announced today that InterVideo's WinDVDTM software DVD player, when combined with NVIDIA's RIVA TNTTM 3D processor, has received Windows® Hardware Quality Labs (WHQL) certification for high quality, full frame rate software enabled DVD playback. This new DVD software playback solution is the first to successfully pass Microsoft's rigorous test requirements and achieve the WHQL logo of certification for the RIVA TNT. The WHQL certification was run on a MicronTM Millennia® Pentium® II 450 MHz system.

WinDVD's impressive list of features includes an advanced intuitive user interface, software video window scaling, software and hardware sub-picture alpha blending, software video signal de-interlacing, and software color and brightness control. WinDVD includes state-of-the-art support for VCD disc and MP3 audio file playback, DVD region control and the most powerful and responsive DVD navigator in the industry.

"We've proven that consumer-quality software DVD playback is possible on standard PCs equipped with our RIVA TNT family of processors," stated Dan Vivoli, vice president of product marketing at NVIDIA. "Combined with WinDVD's outstanding user interface and navigation system, this new offering is the consummate DVD player for the mainstream PC market."

"The WHQL logo is the PC equivalent of the Good Housekeeping Seal of Approval," noted Joe Monastiero, vice president of sales and marketing at InterVideo. "The combination of InterVideo's and NVIDIA's technical expertise in software DVD and graphics processors is exemplified in being the first to achieve WHQL."

WHQL Approval Required For Software DVD Products
The WHQL logo has become a de-facto standard for software enabled DVD playback systems and many major U.S. system manufacturers now require the logo before shipping software DVD solutions. Microsoft's WHQL tests ensure software DVD players offer a compliant implementation of DirectShowTM APIs, support for a proper DVD navigation and a bug-free user experience. Unlike competitive solutions that require the usage of proprietary-based hardware implementations for DVD playback, the WinDVD and RIVA TNT combination is a standards-based solution that has been optimized to ensure high quality DVD playback.

WinDVD supports all of the industry-standard DVD APIs, including DirectShowTM, DirectDrawTM and DirectSoundTM, and is legacy compatible with the MCI interactive title standard. In addition, InterVideo has a unique application interface layer to allow WinDVD to quickly support any graphics adapter with DVD hardware-assist features, like motion compensation and IDCT. WinDVD's architecture is uniquely modular and tightly tailored to the DVD specification and the intricacies of the PC system environment, providing the most seamless navigation experience available. WinDVD is available for licensing to OEMs directly and distribution for system integrators.
