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, performs the inter-layer prediction of the current picture by using the corresponding picture of the determined lower layer, restores the current picture by using a prediction sample acquired through the inter-layer prediction and a residual sample of the current picture, and selectively applies a loop filter to a tile boundary of the restored current picture on the basis of a layer filter flag for the upper layer.

Claim (Index 18):
The method according to  claim 16 , wherein the corresponding picture of the lower layer is a picture to which a 4-tap filter is applied for performing inter-layer prediction of chrominance component of the current picture, wherein coefficient sets of the 4-tap filter include {\u22122, 62, 4, 0}.
