Patent ID: 8265159

Claim:
A moving picture decoding apparatus which decodes an inputted coded moving picture stream with reference to previously decoded macroblock information that is information on a macroblock basis and includes at least motion vector information, said moving picture decoding apparatus comprising: a judging unit configured to judge whether or not an error is present in the coded moving picture stream; a decoding unit configured to decode a current picture to be decoded included in the coded moving picture stream, so as to generate picture data; and a storage unit configured to store macroblock information of the coded moving picture stream and the decoded picture data in association with each other, wherein said storage unit is configured to store, when said judging unit judges that the error is present, information indicating the presence of the error, in association with the macroblock information, and said decoding unit is configured to modify a decoding operation when the macroblock information is the macroblock information in which the error is present, in the case of decoding the coded moving picture stream in a decoding mode in which decoding is performed with reference to macroblock information of a previously decoded picture.
