Abstract
A compressed code decoding device of the present invention includes: a decoding section for receiving a plurality of groups of blocks of compressed codes and decoding each of the blocks of compressed codes; a buffer section for storing decoded signals decoded by the decoding section; a reproduction time acquisition section for acquiring a reproduction time at which to reproduce a predetermined one of the blocks; an output section for externally outputting the decoded signals stored in the buffer section; a detection section for detecting that the predetermined block of compressed codes has been decoded and output via the output section; an addition section for, at a time when the detection section detects that the predetermined block has been output, adding a time required for reproducing the predetermined block to the reproduction time acquired by the reproduction time acquisition section so as to produce a synchronization time; a synchronization section for comparing the synchronization time produced by the addition section and a current time so as to determine whether the synchronization time is ahead of or behind the current time; a code discarding section for, if the synchronization section determines that the synchronization time is ahead of the current time, discarding either compressed codes of one of the blocks next to the predetermined block or compressed codes of one of the groups next to the group including the predetermined block; and a reproduction delay section for, if the synchronization section determines that the synchronization time is behind the current time, delaying output of either decoded signals of the compressed codes of one of the blocks next to the predetermined block or decoded signals of the compressed codes of one of the groups next to the group including the predetermined block.
