In an MPEG picture processing apparatus, a for-reconstructed-picture data transfer for picture data relating to the decoding performed in a video decoder is performed between the video decoder and an SDRAM, and a second type data transfer for each second type of data is performed between a local buffer and the SDRAM. The for-reconstructed-picture data transfer is preferentially performed at a fixed data transfer quantity in an optimum transfer time-period of the picture data. To preferably perform the for-reconstructed-picture data transfer, a possible data transfer quantity of each second type of data is limited to a minimum value in the optimum transfer time-period of the picture data, and the limitation for the possible data transfer quantity is weak in a non-limited time-period other than the optimum transfer time-period of the picture data. Therefore, the decoding in the video decoder can be efficiently performed even though the number of second types data is increased or the possible data transfer quantity of one second type of data is suddenly changed. Also, each second type data transfer is performed in the non-limited time-period. Therefore, each second type data transfer can be preferably performed.
