Analog Devices Inc. (ADI, Wilmington, MA) announced that NHK (Japan), a major national broadcast company, has incorporated ADI's JPEG2000 image compression chip into its latest Hi-Vision, high-definition television (HDTV) advancement. NHK Science and Technical Research Laboratories (STRL) announced the development of the 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 12mm x 12mm package, ADI has enabled STRL to develop a system that employs features of the JPEG2000 standard efficiently.
