ABSTRACT:
In storing decoded image data of a picture into a memory 23, PTS1 and a valid/invalid flag F1 corresponding to the picture are stored at the top boundary address ADR1 of a storage area within the memory 23, ADR1 is temporarily held in a register circuit 211. whether a read address ADR coincides with any one of addresses ADR1 to ADR3 within the register circuit 211 is detected while sequentially reading data from the memory 23 to display a picture. When coincidence is detected, the data read from the memory 23 are retrieved as PTS and F, and control corresponding to a time difference between STC and retrieved PTS is executed if F indicates validity. When coincidence is not detected, the data read from the memory 23 are used as display decoded image data DAT4.
