Title:
VIDEO ENCODING AND DECODING METHOD, AND APPARATUS USING SAME
Document Type and Number:
WIPO Patent Application WO/2014/175658
Kind Code:
A1
Abstract:
The present invention relates to a method and apparatus for compensating a motion vector of an enhancement layer so as to predict an inter-layer differential coefficient. In the case of generating a differential coefficient in a reference layer using a motion vector of the enhancement layer, motion vector information of the enhancement layer may not be used as is due to different frame rates of the reference layer and the enhancement layer. This problem can be solved by the encoding/decoding apparatus and method comprising the steps of: extracting motion information of the enhancement layer; adjusting the motion information of the enhancement layer; and predicting an inter-layer differential signal.
