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.

Claim (Index 18):
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, based on the tile alignment present flag, a tile boundary alignment flag indicating whether a second restriction is applied, wherein the second 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 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, and wherein when the corresponding picture is used for inter-layer prediction of a current block of the current picture, both x and y components of a motion vector relating to the current block are derived equal to zero.
