INTRA-BASE-LAYER PREDICTION METHOD SATISFYING SINGLE LOOP DECODING CONDITION, AND VIDEO CODING METHOD AND APPARATUS USING THE PREDICTION METHOD

摘要

A method and apparatus for improving the performance of a multi-layer based video codec are provided. The method includes obtaining a difference between a base layer block corresponding to a current layer block and an inter-prediction block for the base layer block; down-sampling an inter-prediction block for the current layer block; adding the difference and the down-sampled inter-prediction block; up-sampling a result of the addition; and encoding a difference between the current layer block and a result of the up-sampling.
