Abstract
Decoding data in a special mode is provided without frequent access to a disk. The reproduced data, corresponding to encoded video frames, is written to a storage memory during a normal mode. Attribute information is stored for each encoded video frame which includes the type of encoding for each encoded video frame and its position within the storage memory. In a special mode, encoded video frames are read from the storage memory in a special sequence. Encoded video frames needed to decode a respective encoded video frame are selectively read from the storage memory according to the attribute information. It becomes unnecessary in the present invention, therefore, to reproduce the data necessary for decoding during a special mode, thereby shortening access to the disk and smoothing reproduction of the encoded video frames during the special mode.
