Compressed coded data playback apparatus, and decoding/playback method of compressed coded data in the same apparatus

摘要

A playback control section 5 obtains identification information (an extension) of compressed coded data recorded on a recording medium 1 or input information designating a decoding scheme from outside; tries decoding, unless the decoding performed in accordance with the identification information obtained or with the decoding scheme corresponding to the input information is carried out normally, with successively switching to other compatible decoding schemes; and performs playback based on the decoding scheme that enables normal decoding.
