METHOD FOR ENCODING VIDEO AND APPARATUS THEREOF

摘要

A method for coding a moving picture and an apparatus thereof are provided to adaptively apply a quantization matrix in a macro block unit based on characteristics of an inputted image, thereby improving coding efficiency and performance. In a method for performing moving picture coding by adaptively using a plurality of quantization weight matrices, the method for coding a moving picture comprises the following steps of: converting an inputted image into at least one macro block; selecting a quantization weight matrix corresponding to each macro block among the plurality of quantization weight matrices; quantizing each macro block by using the selected quantization weight matrix; and performing a variable length coding process by including the quantized macro block, index information about the selected quantization weight matrix, and the plurality of quantization weight matrices.
