ABSTRACT:
Disclosed herein is a variable-length code decoding apparatus including: a code buffer that holds a variable-length code in which the same bit value continues for a given number of bits from the most significant bit; code word detectors each of which reads the variable-length code from the code buffer to detect whether the variable-length code matches a specified code word; a decoded code word determination block that determines a code word decoded; and a configuration information holding section that holds configuration information containing the specified code words and code lengths of the specified code words as arranged in an ascending order of code length.
