Abstract
A moving picture decoding device in which picture data is read from a picture memory responsive to a motion vector to perform decoding the motion-compensated moving picture and in which the picture data is also read in a pre-set sequence for display. With the present moving picture decoding device, the combination of data, that is a word format, for a word simultaneously read from four memory devices (DRAMs), is set so as to be different for the motion compensation and for display. That is, during motion compensation, simultaneous reading of a word consisting of luminance (Y) signal component data D0, D1, D2 and D3 is time-divisionally changed over to simultaneous reading of a word consisting of chroma (C.sub.b and C.sub.r) signal component data D2, D3, D0 and D1. During display, two luminance data D0 and D1 (or D2 and D3) are read out simultaneously with the chroma (C.sub.b and C.sub.r) signal component data D2, D3 (or D0 and D1).
