Abstract: Disclosed are an apparatus and a method of encoding/decoding a video, particularly a method and an apparatus for storing a quantization parameter differential value in a largest coding unit (LCU) based on quadtree splitting and adaptively predicting a quantization parameter value based on context information on neighboring CUs. Quadtree-based quantization parameter encoding and decoding methods and apparatuses effectively show information on a block having a quantization parameter differential value based on splitting information on a CU and adaptively predict a quantization parameter value using context information including a block size, block partition and a quantization parameter of a neighboring CU.

Abstract: The present invention relates to a method and apparatus for encoding/decoding an image, and to a method and apparatus for recording a quantization parameter differential value based on a quadtree segmentation in a largest coding unit (LCU), and adaptively predicting a quantization parameter value based on context information of a neighboring coding unit (CU). The method and apparatus for encoding/decoding a quantization parameter based on a quadtree structure may effectively present block information having a quantization parameter differential value based on segmentation information of a CU, and may perform an adaptive prediction of a quantization parameter value using the context information of the neighboring CU such as a block size, block segmentation, quantization parameter value, and the like.
