METHOD AND APPARATUS FOR INTER-LAYER PREDICTION BASED ON TEMPORAL SUB-LAYER INFORMATION

摘要

The present invention relates to an inter-layer prediction method of an image comprised of a plurality of layers including at least one temporal sub-layer. The inter-layer prediction method includes the steps of: acquiring information about a temporal sub-layer for inter-layer prediction; inducing a reference picture used for inter-layer prediction of a current picture on the basis of the information about the temporal sub-layer; and performing inter-layer prediction of the current picture on the basis of the reference picture.
