<p>A moving picture decoding device in which picture data is read from a picture memory (20) 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 (Cb and Cr) 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 (Cb and Cr) signal component data (D2, D3 (or D0 and D1)). . <IMAGE></p> |
