ABSTRACT:
An image decoding apparatus having: a table selection controller configured to output a syntax selection signal which selects one of a prefix, a suffix, and a syntax; a variable length code decoding device configured to receive a bit stream, the syntax selection signal, and a suffix length, and, by using data contained in the bit stream and the suffix length, simultaneously decode the prefix and the suffix and output the result if the syntax selection signal selects the prefix 1 and the suffix, and decode the syntax and output the result if the syntax selection signal selects the syntax; a level formation device configured to receive the decoded prefix, the decoded suffix, and the decoded syntax, and form and output a level; and a suffix length updating device configured to receive the decoded prefix, the decoded suffix, and the decoded syntax, and update the suffix length.
