INTRA-PREDICTION METHOD FOR MULTI-LAYER IMAGES AND APPARATUS USING SAME

摘要

An intra-prediction method for multi-layer images is provided. The method comprises the steps of: deriving an intraprediction mode of a predictive target block of an enhanced layer; generating an alternative sample for an unavailable reference sample of the predictive target block on the basis of a reference layer for the enhanced layer; and generating a predictive block for the predictive target block by using the intra-prediction mode and the alternative sample.

1. An intra prediction method for a multi-layer video, comprising steps of:
deriving an intra prediction mode of a prediction target block of an enhancement layer; generating a replacement sample corresponding to an unavailable reference sample of the prediction target block based on a reference layer corresponding to the enhancement layer; and generating a prediction block corresponding to the prediction target block using the intra prediction mode and the replacement sample and available reference sample of prediction target block.
