Press Release: September 14, 2004 DivXNetworks Partners With Plextor to Release First DivX Certified PC-Based Personal Video Recorder Users Can Pause Live TV and Record Favorite Shows on Personal Computers; DivX Encoding Offers 300% More Compression than MPEG-2 FREMONT, Calif. – DivXNetworks, Inc., the company that created the revolutionary, patent-pending DivX® video compression technology, and Plextor® Corp., a leading developer and manufacturer of high-performance digital media equipment, today announced that the Plextor ConvertX™ PX-TV402U Personal Video Recorder (PVR) with built-in TV tuner is the first official DivX Certified™ Personal Video Recorder to reach the market. The new ConvertX PX-TV402U captures and encodes broadcast, cable, or satellite TV onto a computer hard drive. Users can watch, pause, and record live TV, or use an integrated electronic programming guide to schedule recordings with a single mouse click. In addition to encoding programs, movies, and sports events from a TVsource, ConvertX also supports capturing home video from such sources as camcorders, DVD players, and VCRs through its built-in composite and S-Video inputs. Before certifying ConvertX, the DivXNetworks expert team of video engineers subjected the device to a rigorous testing process to ensure high performance and interoperability with all versions of DivX video. The ConvertX Model PX-TV402U will be available in late September for $199 at www.divx.com/hardware. “Plextor video capture products have been popular with the DivX user community ever since they were first introduced early in 2004,” said Bill Holmes, Director of Product Management for Consumer Electronics at DivXNetworks, Inc. “With the introduction of the PX-TV402U, now people can record TV on their PC using the DivX format. Its support of the DivX Home Theater, Portable and HandHeld profiles makes the PX-TV402U perfect for people who want to play back their programs on DivX Certified DVD players, PDAs, cell phones or personal video players. “The ConvertX PX-TV402U supports traditional compression formats like MPEG-1, MPEG-2 and MPEG-4, but the addition of the DivX format puts this product ahead of the competition,” said Howard Wing, Vice President of Sales and Marketing, Plextor. “Millions of people around the world are using the DivX format and with DivX Certification of the PX-TV402U, they can be confident that the programs they record can be played back in their DivX Certified player.” With the launch of the DivX Certified Program for encoding devices, DivXNetworks includes a full DivX software development kit, rigorous certification testing, and marketing and sales support focused on helping third party development and OEM partners create DivX Certified hardware encoding solutions.
