INTERLEAVED MOVEMENT VECTOR CODING METHOD BASED ON CONTENTION, DECODING/ENCODING APPARATUS, AND METHOD THEREOF CAPABLE OF IMPROVING VIDEO DATA COMPRESSION PERFORMANCE

摘要

PURPOSE: An interleaved movement vector coding method based on contention, decoding/encoding apparatus, and method thereof are provided to acquire high restoration image quality by effectively compressing residual information and a motion vector.;CONSTITUTION: A prediction order determination unit(110) determines the upper and lower priority component of a motion vector in a current block. An upper priority prediction unit(130) calculates the upper priority component of the motion vector from an optimized prediction block group. A lower priority prediction unit(140) calculates the lower priority component of the motion vector from a lower priority prediction block group. A motion information encoding unit(150) encodes a lower priority difference value, an upper priority difference value, and information for the optimized prediction block group.;COPYRIGHT KIPO 2012
