DV Digital Camcorder Technology Offered by QuArc; Videris - DV Video Encoder/Decoder Enables Creation and Playback of Digital Camcorder Movies.Business Editors/High-Tech Writers IP 2000 Booth 319 SANTA CLARA Santa Clara, city, Cuba Santa Clara (sän`tä klä`rä), city (1994 est. pop. 217,000), capital of Villa Clara prov., central Cuba. , Calif.--(BUSINESS WIRE)--March 20, 2000 Digital video innovator QuArc, Inc. today announced the newest member of its Videris(TM) technology family: Videris - DV(TM), its DV-based encoder/decoder core intellectual property (IP) for use in IEEE (Institute of Electrical and Electronics Engineers, New York, www.ieee.org) A membership organization that includes engineers, scientists and students in electronics and allied fields. 1394 and digital camcorder semiconductor products. DV is the international standard used in digital camcorders to compress and decompress To restore compressed data back to its original size. (compression, data) decompress - To reverse the effects of data compression. video information. The company will be showing its digital video technology at IP 2000 in Booth 319 of the Santa Clara Convention Center on March 21, 2000. "DV Digital Camcorders with IEEE 1394 have set the standard in mobile digital video recording," said Ron Richter, QuArc, Inc.'s Vice President Sales and Marketing. "But in order for future Firewire and Digital TV appliances to be compatible with them, you'll need a technology bridge that can playback pre-recorded digital movies with high quality. Videris - DV is that bridge." About Videris - DV Videris - DV supports a wide range of digital video compression Encoding digital video to take up less storage space and transmission bandwidth. See video codec and data compression. video compression - Compression of sequences of images. standards and formats, including DV25 (DV SD), SMPTE (Society of Motion Picture and Television Engineers, White Plains, NY, www.smpte.org) A professional society for motion picture and TV engineers with more than 9,000 members worldwide. It prepares standards and documentation for TV production. 314M 25 and 50 Mbps (DVCPRO-25 & 50), and DV SDL (Specification and Description Language) A modeling language used to describe real time systems. It is widely used to model state machines in the telecommunications, aviation, automotive and medical industries. for long play. In addition to the SMPTE and Matsushita standards, Videris - DV implements QuArc's DV extension (QDV QDV Quick Disconnect Valve QDV Quick Decisive Victory (TM)), which provides user-level control over the compression ratio compression ratio Degree to which the fuel mixture in an internal-combustion engine is compressed before ignition. It is defined as the volume of the combustion chamber with the piston farthest out divided by the volume with the piston in the full-compression position ( for optimizing storage space or improving encoding quality. The result is real-time, studio-quality encoding and multi-stream video decoding. Typical uses of Videris - DV include consumer and professional video editing, digital camcorders, digital TV and VCRs, and Firewire appliances that support video.
Features of Videris - DV include:
-- SMPTE and Matsushita DV standards implementation
-- Multiple video stream decoding
-- Adaptive quantization algorithm support for high-quality
encoding
-- 8 to 80 Mbits/sec. user-setable compression
-- CIF and square pixel format support for NTSC & PAL
-- Small size (60 - 75k gates + 2,048 bytes SRAM)
Customers who wish to integrate QuArc's core video IP into their semiconductor products receive: A gate-level netlist, bit-accurate "C" Model, functional test bitstreams, Verilog simulation shells and support scripts, full documentation and example adaptive quantization algorithm software. (Verilog source code is optional.) Videris - DV comes as an encoder/decoder or decoder-only core IP, and will be available to licensed customers in July of 2000. About the Videris Family Videris - DV builds upon the success of its associated technology, Videris - HD. Videris - HD is QuArc's powerful video decoder, capable of processing HDTV (High Definition TV) A set of digital television (DTV) standards that offer the highest resolution and sharpest picture. Although some HDTV sets are available in standard (rather square) screen sizes, the overwhelming majority of sets are wide screen, which eliminates MPEG-2 video data or up to eight DSS/DVB video streams using its Multi-Video TV(TM) technology (MVTV(TM)). The Videris - HD decoder requires only 70k-90k gates with 1,600 bytes of SRAM See static RAM. SRAM - static random-access memory . Typical applications for Videris - HD include high-definition & digital TV receivers, set-top-boxes, PC graphics, games, digital and high-end analog VCRs, MPEG-2 digital still or movie cameras, studio-quality video editing and Internet appliances. Videris - HD supports both 4:2:0 and 4:2:2 formats for standard and high-definition decoding. About QuArc Founded in January of 1998, Santa Clara, California-based QuArc, Inc. is a privately held company privately held company A firm whose shares are held within a relatively small circle of owners and are not traded publicly. that specializes in video hardware and software intellectual property development and licensing. The company is both a fabless and chipless hardware supplier. QuArc's family of Videris(TM) digital video products includes high-definition MPEG-2 decoding (Videris - HD) and DV encoding/decoding (Videris - DV). QuArc has leveraged its extensive digital video and audio expertise to produce the patented architecture, high performance and low gate count reflected in its digital video technology.
