摘要： While temporal and spatial direct modes are both supported, the amount of temporarily-stored direct-mode prediction information is reduced, thereby reducing the memory bus bandwidth. A motion information generator combines a motion vector for an anchor block with the number of a reference picture of the anchor block, thereby generates motion information of the pixel block. A still-state determination unit determines whether or not the pixel block is considered still based on the motion vector for the anchor block and on the number of the reference picture. A selector selectively stores in a memory either an output of the motion information generator or a determination result of the still-state determination unit as direct-mode prediction information of the pixel block. A motion vector predictor predicts a motion vector for the pixel block in direct mode based on the direct-mode prediction information stored in the memory.

摘要： To correct a bit shift of binary data read from a medium and further enable correction of a bit error caused by mis-correction of the bit shift, a data recovery apparatus according to the present invention comprises: circuits for respectively correcting time at an intersection of a read signal and a slice signal; and a circuit for generating gray bits representing a time cell including an intersection, the time of the intersection being uncorrected and a time cell adjacent to the time cell, positioned in the direction of the intersection being shifted for correction.
