Analog Devices' JPEG2000 IC Powers Japanese HDTV Broadcast System.Business Editors/High-Tech Writers NORWOOD, Mass.--(BUSINESS WIRE)--June 12, 2003 -NHK NHK - Nippon Hoso Kyokai (Japan Broadcasting Corporation) NHK - Nihon Hikikomori Kyokai (anime) NHK - Nihon Hoso Kyokai (Japanese Broadcasting Association) NHK - Normal Human Epidermal Keratinocyte adopts ADI's JPEG2000 compression IC to enable world's first real-time encoder and decoder board for Hi-Vision television applications. Analog Devices Inc. (NYSE: ADI), a global leader in high-performance semiconductors for signal processing applications, today announced that NHK, a major national Japanese broadcast company, has incorporated ADI's JPEG2000 image compression chip into its latest Hi-Vision high-definition television (HDTV) 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 (mathematics) wavelet - A waveform that is bounded in both frequency and duration. Wavelet tranforms provide an alternative to more traditional Fourier transforms used for analysing waveforms, e.g. sound. The Fourier transform converts a signal into a continuous series of sine waves, each of which is of constant frequency and amplitude and of infinite duration. 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 They Used to Be the Norm In earlier PCs, all peripheral controllers were housed on expansion boards, including the disk controller, serial and parallel ports, sound and display. Today, all the peripheral control may be included in the chipset (see PC chipset). In such cases, users still have the option of plugging in their own controllers., 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 See recursion. filtering) wavelet technology that enables real-time compression and decompression of high-quality moving and still digital images. The ADV202 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 (graphics, file format) image formats - There are many formats used to store images in files. GIF, TIFF and JPEG are very common. Others are BIFF, bmp, Clear, FITS, IFF, NFF, OFF, PCX, PNG, TGA, XBM. Some of these are documented on-line at the following sites: The Graphics File Format Page. The NCSA file formats archive. The Avalon repository. 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.

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) in hierarchical and multi-step combinations. Unlike MPEG4, JPEG2000 does not require the payment of a patent license fee.
