Abstract
Any type of media data can be played back on a receiving side regardless of quality conditions of a data transmission line. Therefore, in a differential motion vector limiting unit , the number of cases of the inputting of “1” as quality conditions of a data transmission line is counted and held for each unit time by using an internal timer. In simultaneous with the holding of the counted number, a differential motion vector limiting unit refers to the counted number according to input position information of a to-be-coded macro-block for each picture, and differential motion vector limiting information is determined according to the referred counted number. In a motion compensation predicting unit , a differential motion vector is calculated, and the differential motion vector is compared with the differential motion vector limiting information . In cases where the calculated differential motion vector is beyond the differential motion vector limiting information , the differential motion vector is replaced with the differential motion vector limiting information to set a limit to the differential motion vector, and the motion vector is output to a VLC unit
