Method and apparatus for inter prediction decoding with selective use of inverse quantization and inverse transform
The present disclosure relates to a method and an apparatus for motion vector encoding/decoding through estimations of multiple motion vectors, and to a method and an apparatus for video encoding/decoding using the same. The disclosure provides a motion vector encoding apparatus including a motion vector estimator for estimating a plurality of motion vectors with estimating one of the plurality of motion vectors as a motion vector of a current block and estimating the remaining motion vectors by one or more predefined estimation criteria in agreement with a video decoding apparatus; and a motion information encoder for encoding motion information generated by using the plurality of motion vectors. According to the disclosure, estimations are enabled by using more accurate motion vectors while reducing the bit rate for encoding the motion vectors leading to an improvement of the compressing efficiency.
