    摘要： A method and device for interleaving bit stream so that a bit stream can be seamless-reproduced from a multimedia optical disk (M) which is used efficiently by recording data shared by a plurality of titles and has a data structure that realizes such a new function as the multi-angle reproduction. The data structure is such that a plurality of video objects (VOB) containing compressed video data are recorded on the multimedia optical disk (M) in the order of reproduction in interleave areas (blocks 4 and 6) and continuous areas (blocks 1, 2, 3, 5, and 7) and a management are (NV) in which data are interleave-recorded together with the video data is provided. The information which specifies the information on the end position of the area from which data are read out continuously and the information on the position where the data can be reproduced next on the disk are recorded in the management area.

    摘要： An image coding apparatus according to the present invention is provided with, as shown in figure 4, a blocking circuit 401 for dividing an input image signal into two-dimensional blocks each comprising plural pixels; a frequency distribution verifier 408 for calculating the average and variance from a plurality of image feature data 402 to 407 and the frequency distribution of each feature data for each block in a predetermined period; a filter characteristic decider 409, a filter circuit 410, and an encoder 411.
    In the image coding apparatus so constructed, the input image signal is divided into local regions each comprising plural pixels, the image feature data of each local region is extracted, the average and the variance of the extracted image feature data are calculated from the frequency distribution of the image feature data for a predetermined period, and a filter characteristic and a quantization step are decided for each local region according to the degree of singularity of each local region. Thereby, the quantity of generated codes can be controlled more precisely as compared with the conventional apparatus, and a portion of the decoded image where coding noise is conspicuous can be locally suppressed.
