    摘要： A motion vector holding unit 61 holds motion vector information with respect to a backward reference frame detected beforehand and received from a motion compensation unit 60. A motion vector calculation unit 63 calculates multiple motion vectors for each macro block defined in a coding target frame with reference to the motion vector information with respect to the backward reference frame held by the motion vector holding unit 61 according to each calculation mode of a set of different calculation modes. A motion compensation prediction unit 64 performs motion compensation using motion vectors obtained for each calculation mode, thereby creating predicted images. The predicted images are output to a coding amount estimation unit 65. The coding amount estimation unit 65 estimates the coding amount of the subtraction image, which is the subtraction between the predicted image and the original image, for each calculation mode. A motion vector selection unit 67 makes a comparison between the coding amounts of the subtraction images, and selects the motion vector which provides the smallest coding amount.

    摘要： A motion vector coder performs coding on motion vectors MV0, MV1 and MV2 in the stated order. Initially, the motion vector coder receives the motion vectors MV0-MV2 from a motion vector holder. The motion vector coder codes the motion vector MV0 at the lowest layer 0. Subsequently, the motion vector coder codes (½*MV0-MV1), which is a difference between ½ of MV0 and MV1, instead of coding the motion vector MV1 at layer 1. The motion vector coder then codes (½*MV1-MV2), which is a difference between ½ of MV1 and MV2, instead of coding the motion vector MV2 at layer 2.

    摘要： A data buffer receives and temporarily stores data including a product code enabling error correction in first and second directions. An exclusive-OR operation circuit uses an error amount detected by error correction in the first direction and data stored in a storage element to calculate a first error check result. A PI direction error-checking circuit according to the first error check result performs error check after error correction in the first direction. A PO direction partial error-checking circuit and a PO direction aggregate error-checking circuit use an error amount detected in error correction in the second direction and calculate a second error check result. The first and second error check results are used to generate a final error check result by an exclusive-OR operation circuit.

    摘要： Structure information on picture within a GOP of a coded data sequence is acquired beforehand. At the time of high-speed reproduction, a high-speed reproduction mode judging unit judges by referring to the picture structure information whether a high-speed smooth reproduction is possible or not. If the high-speed reproduction is possible, a high-speed smooth reproduction control unit performs the high-speed smooth reproduction. If not possible, a high-speed skip reproduction control unit performs high-speed skip reproduction. For reverse reproduction, image data for one GPO, for example, are recoded by an MPEG encoder and then the recoded image data are stored in a storage. Then, a coded data amount predicted from the structure information on the picture within the GOP is compared with the capacity of the storage, and a countermeasure such as raising a compression ratio is taken if the estimated coded data amount exceeds the capacity of the storage.

    摘要： A region setting unit 64 sets multiple global regions in a frame image. A bit number adjustment unit 62 adjusts the number of bits of the local motion vectors LMV which are to be obtained for each global region. A local motion vector detection unit 66 detects the local motion vectors LMV with the number of bits adjusted by the bit number adjustment unit 62 in units of macro blocks for each global region. A global motion vector calculation unit 68 calculates the global motion vector GMV which represents the global motion for each global region. A local motion vector difference coding unit 72 calculates the difference ΔLMV, which is the difference between each local motion vector LMV and the global motion vector GMV, for each global region, and performs coding thereof.
