A method for decoding a multi-layer video signal, according to the present invention, determines whether a corresponding picture in a lower layer is used as an interlayer reference picture for a current picture in an upper layer, on the basis of a time level identifier of the lower layer, performs interlayer prediction for the current picture by using the corresponding picture if the corresponding picture in the lower layer is used as the interlayer reference picture for the current picture in the upper layer, restores the current picture by using a prediction sample acquired through the interlayer 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. |
