ABSTRACT:
An apparatus decodes data of unknown frame length. The decoding apparatus includes a preliminary decoding part and a decoded data outputting part. The preliminary decoding part decodes data into preliminarily decoded data according to each of the possible frame lengths. The decoded data outputting part selectively outputs data among the preliminary decoding data that correspond to a detected frame length. Accordingly, memory can be efficiently utilized, and decoding efficiency deterioration is prevented.
