Video decoding method, encoding method, and decoding device using quadtree structure

Abstract

Disclose video encoding/decoding method, coding method and the decoding device using quad-tree structure.The video encoding/decoding method using quad-tree structure includes: the decoding comprehensive code block mark information in coding unit；Based on the dimension information in the comprehensive code block mark information and transform block, to decode separation information flag；With when be not based on this separate information flag add separate the transform block when, decode the code block mark information in the transform block, wherein when there is no the transformation coefficient in the transform block, the separation information flag is not decoded, wherein when the value of the separation information flag is equal to predefined value, additional separation is not carried out to the transform block.
