Analog Devices' JPEG2000 IC Powers Japanese HDTV Broadcast System.


Business Editors/High-Tech Writers

NORWOOD, Mass.--(BUSINESS WIRE)--June 12, 2003

-NHK adopts ADI's JPEG JPEG

, a major national Japanese broadcast company, has incorporated ADI's JPEG2000 image compression chip into its latest Hi-Vision high-definition television (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 ) advancement. This May, NHK Science & Technical Research Laboratories (STRL STRL Sea Trial ) announced the development of the world's first single, real-time encoder/decoder board based on the JPEG2000 standard, enabled by ADI's JPEG2000 chip.

The board compresses Hi-Vision HDTV signals into the JPEG2000 format and allows broadcasters to simultaneously handle signals required by different media, such as TVs, PDAs, and cell phones. Traditional JPEG2000 encoder/decoder systems for HiVision HDTV signals divide an HDTV picture into small sub-images, using 5/3 wavelet transforms, and are housed in large form-factor equipment. Providing JPEG2000 functionality in ICs housed in a small 12 mm x 12 mm package, ADI has enabled STRL to develop a system that employs features of the JPEG2000 standard efficiently. As an example, by using 9/7 wavelet transform technology in the JPEG2000 standard, the ICs are able to process an HDTV picture as a single tile without the need to break it into smaller parts to process. ICs sit on a single PC expansion board, which significantly reduces the space required for the system.

ADI's JPEG2000 Development

Analog Devices is the first company to have developed an IC dedicated to the JPEG2000 standard. ADI's solutions allow the extraction, compression, and transmission of video images at varying resolutions without further signal processing and using half the amount of memory required by the original JPEG standard. ADI's solutions feature the company's SURF(TM) (spatial ultra-efficient recursive filtering) wavelet technology that enables real-time compression and decompression of high-quality moving and still digital images.

202 is an image codec IC supporting the JPEG2000 standard, capable of real-time compression and decompression of high-resolution moving and still digital images. With a flexible interface, the ADV202 can be used with multiple types of video and still image formats and comes in a compact 12mm x 12mm BGA package. The ADV202 will be sampling in July and will be in full production at the end of 2003. For more information, please visit www.analog.com/ADV202.

About the JPEG2000 Standard

JPEG2000, which was established as an international standard in January 2001, is a still image compression standard based on wavelet transforms. The wavelet transform is a technology that processes two-dimensional filtering and sub-sampling (pixel decimation DECIMATION. The punishment of every tenth soldier by lot, was, among the Romans, called decimation. ) in hierarchical and multi-step combinations. Unlike MPEG (Moving Pictures Experts Group) An ISO/ITU standard for compressing digital video. Pronounced "em-peg," it is the universal standard for digital terrestrial, cable and satellite TV, DVDs and digital video recorders (DVRs). 4, JPEG2000 does not require the payment of a patent license fee.
