<p>PROBLEM TO BE SOLVED: To provide an MPEG video decoder capable of reducing frame omissions caused in reproduced moving images and improving visibility. SOLUTION: When decided that the occupancy amount Bm of a bit buffer 2 is below a third threshold BTH3 or the bit buffer 2 causes underflow, an underflow control circuit 12 stops the read of pictures from the bit buffer 2 and successively outputs (repeats) video output which is the decoded result of not the picture processed concurrently but the picture read from the bit buffer 2 previously from a decoding core circuit 4.</p> |
