Abstract:
1. A decoding apparatus comprising: a single decoder for receiving plural coded data, and decoding the respective coded data to output decoded data; and a decoding state holder for holding plural states of said decoder; wherein said decoder is operable to perform processes of selecting coded data to be a target of decoding, from among the plural coded data to be decoded, cyclically decoding divided portions of a predetermined unit of the selected coded data, saving its own state in said decoding state holder at a timing when decoding of a respective one of the divided coded data portions of the predetermined unit is completed, restoring its own latest state from said decoding state holder at a timing when decoding of a respective one of the divided coded data portions of the predetermined unit is started, outputting plural decoding results to the corresponding destinations, and completing a series of the processes within a predetermined period of time corresponding to each coded data.
