PURPOSE: A method for decoding Huffman code is provided, which minimizes a retrieval time and reduces the number of required memories using group information displaying existence information of Huffman code. CONSTITUTION: According to the method for decoding Huffman code, the first step provides a Huffman code table per group and a group retrieval table where Huffman code is grouped according to a bit pattern. The second step finds a group by analyzing input bit stream, on the basis of the group retrieval table provided in the first step. And the third step finds decoding symbol corresponding to the bit stream inputted from the corresponding group Huffman code table, after finding the group of the second step.
