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 time level identifier of the lower layer, and restrictively performs inter-layer prediction for the current picture on the basis of a tile boundary alignment flag indicating whether tile alignment is performed between the upper layer and the lower layer if the corresponding picture in the lower layer is used as the inter-layer reference picture for the current picture in the upper layer.

Claim (Index 19):
A method for encoding a multi-layer video signal with an encoding apparatus, the method comprising:\n 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 a layer tile enabled flag in response to a value of the tile alignment present flag, wherein the layer tile enabled flag indicates whether a second restriction is applied and the second restriction is to restrict all picture belonging to an upper layer to consist of a plurality of tiles; encoding, based on the layer tile enabled flag, a tile boundary alignment flag indicating whether a third restriction is applied, wherein the third restriction is to restrict i) two samples of a corresponding picture of the lower layer to 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 to 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 at least one of the tile alignment present flag, the layer tile enabled flag and the tile boundary alignment flag, wherein the corresponding picture of the lower layer is a picture to which a re-sampling filter is applied for performing inter-layer prediction on the current picture.
