Abstract
A first bit string extracting unit extracts a first bit string. A first bit length judging unit detects a first codeword from the first bit string. A first decoding unit generates a first run-level pair from the first codeword. A second bit string extracting unit extracts a second bit string. A second bit length judging unit detects a second codeword from the second bit string. A second decoding unit generates a second run-level pair from the second codeword. A first inverse quantizing unit inverse quantizes the first level to obtain a DCT coefficient. A second inverse quantizing unit inverse quantizes the second level to obtain a DCT coefficient. A second buffer controller writes the DCT coefficients and their first buffer addresses into a second buffer. A first buffer controller reads the DCT coefficients and the first buffer addresses from the second buffer and writes the DCT coefficients into a first buffer at the respective first buffer addresses.
