Abstract:
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 inter-layer reference picture for a current picture in an upper layer, on the basis of a temporal level identifier of the lower layer, performs inter-layer prediction for the current picture by using the corresponding picture if the corresponding picture in the lower layer is used as the inter-layer reference picture for the current picture in the upper layer, reconstructs 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 reconstructed current picture on the basis of a layer filter flag for the upper layer.

Claim (Index 19):
A method for encoding a multi-layer video signal with an encoding apparatus, the method comprising:\n performing an inter-layer prediction on a current picture of an upper layer using a corresponding picture of a lower layer; encoding a maximum temporal level identifier relating to the lower layer, the maximum temporal level identifier indicating a maximum temporal level identifier to which the inter-layer prediction of an upper layer is allowed; encoding, a tile alignment present flag indicating whether a first restriction is applied, wherein the first restriction is to restrict all pictures belonging to a video sequence to consist of a single tile, encoding, based on tile alignment present flag, a layer filter flag indicating whether a second restriction is applied, wherein the second restriction is to restrict a loop filter is not to be applied to tile boundaries of each picture belonging to the upper layer; and encoding, based on tile alignment present flag, a tile boundary alignment flag indicating whether a third restriction is applied, wherein the third restriction is to restrict that i) two samples of the corresponding picture of the lower layer belong to one tile, when two samples of the current picture of the upper layer belong to one tile, and ii) the two samples of the corresponding picture of the lower layer belong to different tiles, when the two samples of the current picture of the upper layer belong to different tiles; and generating, a bitstream including the maximum temporal level identifier, the tile alignment present flag, the layer filter flag and the tile boundary alignment flag.
