There is provided a H.264 decoding method for fast CAVLC, which searches multiple tables effectively and fast to obtain coefficients for CAVLC blocks within the shortest period of time such that a decoder with excellent efficiency can be designed for low frequency. The H.264 decoding method for fast CAVLC includes: a first step of obtaining the number of ‘0’s including the firstly inputted bit ‘0’ to the bit ‘0’ right before the bit ‘1’ firstly appearing to obtain a row index value; a second step of obtaining a fix index indicating the first bit ‘1’; a third step of obtaining a column index indicating a bit stream other than the row index and fix index; and a fourth step of obtaining a total coefficient and trailing ones T1s corresponding to the row index value and the column index value.
