Abstract: PURPOSE: A video encoding apparatus is provided to improve the coding efficiency by adaptively selecting quantization matrix and performing the quantization. CONSTITUTION: A quantization matrix selection unit(120) selects an intra quantization matrix corresponding to an intra prediction mode. A quantization matrix internal product unit(130) computes the selected intra quantization matrix and a weighted value for converting the quantization matrix. A quantization unit(140) quantizes the computed result of the quantization matrix.
