METHODS OF CODING BLOCK INFORMATION USING QUADTREE AND APPARARUSES FOR USING THE SAME

摘要

PURPOSE: An image encoding method using a quad tree and a storage medium readable by a computer are provided to increase the image encoding efficiency by decoding the conversion unit information using a quad tree. CONSTITUTION: An image decoder decodes pattern information on the basis of the conversion unit information integrated flag information (S1200). The image decoder decodes division code block flag corresponding to a pattern or division information flag information on the basis of the decoded pattern information (S1210). [Reference numerals] (AA) Start; (BB) End; (S1200) Decode pattern information on the basis of conversion unit information integrated flag information in a conversion unit; (S1210) Decode division code block flag corresponding to a pattern or division information flag on the basis of the decoded pattern information
