METHOD, MEDIUM, AND APPARATUS ENCODING AND/OR DECODING AN IMAGE USING THE SAME CODING MODE ACROSS COMPONENTS

摘要

A method, medium, and apparatus encoding and/or decoding an image in order to increase encoding and decoding efficiency by performing binary-arithmetic coding/decoding on a binary value of a syntax element using a probability model having the same syntax element probability value for respective context index information of each of at least two image components.
