Abstract:
The multilayer video signal decoding method according to the present invention is characterised in that whether or not a corresponding picture in a lower layer is being used as an inter layer reference picture for a current picture in an upper layer is determined on the basis of a time level identifier for the lower layer, and if the corresponding picture in the lower layer is being used as an inter layer reference picture for the current picture in the upper layer, inter layer prediction of the current picture is carried out using the corresponding picture, and the current picture is restored using a prediction sample obtained by means of inter layer prediction and a residual sample of the current picture.

Claim (Index 21):
A method for encoding a multi-layer video signal, the method comprising:\n determining whether a first restriction is applied, the first restriction being all pictures belonging to a video sequence consist of a single tile; encoding a tile alignment present flag based on the determination result; encoding, based on the boundaries tile aligned present flag, a layer filter flag indicating whether a second restriction is applied, the second restriction being that a loop filter is not applied to a tile boundary of each picture belonging to an upper layer; encoding, based on the tile alignment present flag, tile boundaries alignment flag indicating whether a third restriction is applied, the third restriction being that when two samples of a current picture of the upper layer belong to one tile, two samples of a corresponding picture of a lower layer belong to one tile, and when the two samples of the current picture of the upper layer belong to different tiles, the two samples of the corresponding picture of the lower layer belong to different tiles; and generating a bitstream including at least one of the tile alignment present flag, the tile boundaries alignment flag or the layer filter flag, wherein the picture of the lower layer is a picture to which a 8-tap filter is applied for performing inter-layer prediction on the current picture and, wherein coefficients of the 8-tap filter include {0, 1, \u22123, 8, 62, \u22125, 2, \u22121}.
