摘要

In a moving picture decoding apparatus compliant with a coding standard, such as CABAC of H. 264 and the like, for coding of a stream including arithmetic coded data, a first type variable length decoding section performs first variable length decoding including arithmetic decoding to input stream data to generate first stream data beforehand. The first recording control section records a key frame which is selected from the first stream data not needing arithmetic decoding and is necessary in special playback in a first recording region. In decoding, the recorded key frame not needing arithmetic decoding is used, a decoding time is reduced. Accordingly, even when a moving picture stream for special playback such as multiple-fold speed playback is performed, reverse playback and the like, as smooth special playback as known special playback of a moving picture signal which does not include arithmetic coded data can be achieved.
