Abstract
In a packing unit (PU) composed of five sync blocks, Discrete Cosign Transform (DCT) blocks of compressed and encoded data are packed to a sync block. When same DCT blocks are not placed in a sync block, the remaining DCT blocks are temporarily placed in another sync block. In a high speed reproducing mode, a detecting portion detects whether or not the current PU mixes with data of another PU. The detected result is supplied as a flag to an unpacking portion along with a sync block. The unpacking portion removes a sync block that mixes with data of another PU. The unpacked data is supplied to a Bit Rate Reduction (BRR) decoder. The BRR decoder performs a decompressing process.
