The next-generation picture coding standard, the JPEG2000, has rich features of high-compression efficiency and scalable handling of images, and so is expected to be used not only for still pictures, but also for compressing video with high quality. We have constructed a prototype codec of JPEG2000 with compact PC extension card size and applied it to HDTV motion picture recording following the Motion-JPEG2000 format. The codec compresses the HDTV signals in an intra-field manner using the core technology of IR 9x7 Wavelet conversion of the JPEG2000 Part-1 Standard, processing a single tile per field. The codec consists of a single PC extension board attached to a PCI 64-bit bus. This paper outlines the architecture of the codec and its coding performance by the experiment.
