SCALABLE VIDEO CODING METHOD AND APPARATUS USING INTRA PREDICTION MODE

摘要

The present invention relates to a scalable video coding method and apparatus using an intra prediction mode. A decoding method includes configuring a maximum probability mode set for predicting an intra prediction mode for a target decoding block of an enhancement layer so that the maximum probability mode set includes an intra prediction mode for a corresponding block of a reference layer and restoring the target decoding block of the enhancement layer using any one of intra prediction modes included in the maximum probability mode set.

1. A method for decoding a scalable video signal based on an inter-layer texture prediction with a decoding apparatus, the method comprising:
determining whether the inter-layer texture prediction is performed on a current picture in a enhancement layer; filtering, based on a resolution difference between the enhancement layer and a reference layer, a reference picture in the reference layer used for the inter-layer texture prediction in response to the determining; obtaining a predicted pixel value of a current block in the current picture by applying at least one of correlation parameters to a reconstructed pixel value of a reference block in the filtered reference picture; and decoding the current block using the obtained predicted pixel value.
