ADI ANNOUNCES BREAKTHROUGH MPEG FULL-MOTION CHIP

 ARLINGTON HEIGHTS, Ill., April 7 /PRNewswire/ -- Dramatically boosting the capabilities of PC computers and other converging multimedia technologies, the first real-time Motion Picture Expert Group (MPEG) encode and decode chip that performs full motion compression at 30 frames per second has been developed by Audio DigitalImaging Inc., a wholly owned subsidiary of ADI Technologies Inc. (OTC: ADIKF).
 The MPEG I single chip parallel processor operates in full duplex mode sustaining simultaneous encode and decode, and will be unveiled in May at the computer trade show, COMDEX/Spring '93, in Atlanta, under the name Apogee I.
 The Application Specific Integrated Chip (ASIC) designated Apogee I performs real-time compression of higher resolution data rates up to 27Mbits or more per second, which falls well within the new proposed MPEG II Standard Data Rate. Regardless of the data rate compression level chosen, compressed video quality remains equal or superior to S-VHS. The chip is capable of handling source material originating from live camera, video tape or film input for compression in real time.
 In addition to its adherence with MPEG standards, the Apogee I embodies many proprietary enhancements that permit deeper video compression levels of approximately 2:1 over MPEG I standards. The chip addresses a double buffer DRAM configuration enabling the additional component of multiple special digital special effects. These ASIC features are designed to aid text overlays with chroma keying, movable and scaleable window placements, zooms, fades, wipes and rotations, etc.
 Because the Apogee I is compatible with CD-ROM Interactive, and can provide still or "freeze frame" video as well as full motion, suitable applications could include PC or workstation authoring terminals for multimedia applications, video camcorders, digital VCRs and camcorders, laser printers, color copiers, video studio editing terminals, as well as consumer devices such as home and arcade video games.
 Although the Apogee is a true ASIC application without any microcode considerations, the chip will offer many user selective features through its register selections, i.e. resolution sizes, maximum data rates, field or frame, field and frame, etc.
 "We wanted to offer more than a standard MPEG compression chip," said Jean Monroe, ADI chairman and chief executive officer. "By addressing the commercial and consumer markets now with a cost- effective single chip capable of fulfilling product voids, we have met our challenge and perhaps exceeded the industry's expectations."
 These voids, Monroe said, include an affordable CD-ROM authoring workstation; a low-cost desk top, full duplex teleconference PC board; real-time MPEG compression for Windows applications; and a realistic low-cost decode-only chip for those applications needing to meet cost limitations. Examples would be terminals used for educational purposes as well as commercial cable TV decode boxes and CD I video games.
 ADI is engaged in discussions with several national and international Original Equipment Manufacturers regarding the Apogee I, which will be available for shipment in chip or PC board form in July.
 Performance factors of the ASIC will include I/O for all CCIR601 standard resolutions of NTSC, PAL and SECAM. Unique to all other MPEG compression products in the market, the Apogee I offers three high levels of pre-process filtering in addition to performing compression in real-time, resulting in an approximate 1.2Mb per second or less data rate which is well within the prescribed MPEG I data rates.
 A stand-alone sister chip, the Apogee-DC, is dedicated to perform decode plus real-time simultaneous scan rate conversions from CCIR601 resolutions to S-VGA in resolutions up to 1280 X 1024.
 "There is no facet within the video compression industry that our Apogee I chip cannot address in a high quality yet cost-affordable way," Monroe said.
 The product is designed by Jeffrey Frederiksen, known as the "father" of microprocessor video games. His creative use of interactive video graphics led to the inventions of such games as Space Invaders and Gun Fighter.
 Audio DigitalImaging Inc. specializes in the research and development of computer-related compression technologies, considered the largest growth sector in the computer electronics industry. The company develops ASIC chips, PC image compression boards and vertical market software application system products that are proprietary, patented, trademarked and/or copyright protected.
