Method and apparatus for encoding/decoding multilayer video signal

Abstract:

A scalable video signal decoding method, according to the present invention, determines a corresponding picture belonging to a lower layer used for an inter-layer prediction of a current picture belonging to an upper layer, and performs the inter-layer prediction of the current picture by using the corresponding picture in the determined lower layer, wherein the inter-layer prediction is restrictively performed according to a tile boundary alignment flag indicating whether tiles between the upper layer and the lower layer are aligned.
