Patent ID: 8620148

Claim:
A compressed coded data playback apparatus which reads compressed coded data recorded on a recording medium and plays back said read data, comprising: an identification information acquiring section configured to acquire identification information of the compressed coded data recorded on the recording medium by referring to a management region of the recording medium; and a playback control section configured to attempt decoding the compressed coded data, when failing to normally decode the compressed coded data in accordance with a decoding scheme corresponding to the identification information, by successively switching to other decoding schemes, and configured to play back the compressed coded data in accordance with a switched-to decoding scheme, which has enabled the compressed coded data to be normally decoded as a result of the attempt of decoding, wherein said playback control section comprises: a decoding selecting section configured to select a decoding scheme in accordance with the acquired identification information; a decoding section configured to decode the compressed coded data recorded on the recording medium in accordance with the decoding scheme selected by said decoding selecting section, and to make a decision as to whether or not the decoding performed by said decoding section was carried out normally; and a decoding switching control section configured to successively switch decoding schemes utilized in the decoding section to decode said compressed coded data when the decoding of said compressed coded data performed by said decoding section using previous decoding schemes have been decided by the control section not to be normally done.
