APPARATUS AND METHOD FOR ENCODING AND DECODING TO IMAGE OF ULTRA HIGH DEFINITION RESOUTLTION

摘要

PURPOSE: An apparatus and method for encoding and decoding an ultra high definition resolution image are provided to reduce the calculation complexity by outputting a bitstream using an estimation block of a current block. CONSTITUTION: A prediction unit(810) creates the estimation block of a current block based on a reference image. A subtracting unit creates the difference block through a difference between the estimation block and the current block. An encoding information generating unit(850) creates the encoding information which shows the encoding state of the differential block.
