| Abstract(in English) | Recently, the importance of scalability functions in video codecs such as SNR, temporal and spatial scalability has been increased. Motion JPEG 2000, which is the Part 3 of the JPEG 2000 standard series, has the advanced SNR and spatial scalability. It is achieved by subband division using wavelet transform and Embedded Block Coding with Optimal Truncation (EBCOT). However, the spatial scalability is limited to the cases where decimated resolution is l/2^n of the source image. When the source image has high resolution like Digital Cinema or HDTV, then we cannot get an SDTV or QVGA size image by decoding Motion JPEG 2000 betstream directly. We developed a software "down-conversion" system, which can generate sequences of different resolutions, such as HDTV, SDTV, CIF, QVGA and QCIF, from Digital Cinema-size video sequences. The system combines LL sub-band of source and the Lanczos3 filter. |
