PURPOSE: A method for recording a multi-level quantization parameter for a macro block based on a quad tree and a device thereof are provided to transmit depth information for quantization separately from depth information of a coding unit by a slide unit. CONSTITUTION: A quantization block unit determining unit(1400) determines the minimum block size of a quantization block. A de-quantization parameter extracting unit(1410) calculates a de-quantization parameter value for a corresponding block using a quantization parameter value using determined block information. A de-quantization performing unit(1420) de-quantizes blocks in a quad tree-based macro block. |
