Apparatus and method for video encoding/decoding and recording medium having recorded thereon program for executing the method

摘要

An intraprediction encoding and decoding apparatus and method to improve compression efficiency are provided. A video encoding method includes dividing an input video of a predetermined size into at least two sub-planes, performing intraprediction encoding on at least one of the divided at least two sub-planes, and performing interprediction encoding on at least one of the remaining sub-planes by using the intraprediction encoded sub-plane as a reference sub-plane.
