PROBLEM TO BE SOLVED: To eliminate the problem of abnormal display of a moving image caused by the lack of received data or by editing incompletely compliant with standards or the problem of non-display of a normal moving image or the lack of a normal moving image.SOLUTION: While the N-1'th GOP_N-1 immediately preceding the N'th GOP_N in a plurality of GOPs is lacking or deleted, a first bidirectional prediction picture of the N'th GOP_N is made decodable. A determination device 38 determines the value of prediction direction information included in the header of a macroblock included in the first bidirectional prediction picture. When the prediction direction information is a forward prediction or a bidirectional prediction, the determination device 38 generates a signal indicating that supply of decoding results to a display device by a display controller 39 be disabled. When the determined prediction direction information is a reverse prediction or an independent prediction, the determination device 38 generates a signal indicating that supply of decoding results to a display device by the display controller 39 be enabled. |
