Coded image data having a DTS (decode time stamp) appended for each frame are written into an input buffer. A portion of the storage area of the input buffer is scanned to produce identification information (ID) for each frame of image data. For each frame of image data, the ID, DTS, storage location in the buffer and coding type are held in the form of a mapping table. The system time clock (STC) is compared with the DTSs in the table. When a match occurs, the storage location for the corresponding frame of image data is read from the table and sent to a decoder, which in turn reads the corresponding image data from the buffer and decodes it.
