Abstract:
The present invention relates to a method for coding a scalable video in a multilayer structure, and a method for encoding a video according to the present invention comprises the steps of: decoding and saving a picture of a reference layer; inducing an interlayer reference picture which is referenced for predicting a current block of a current layer; producing a reference picture list including the interlayer reference picture and a reference picture of the current layer; conducting a prediction on the current block of the current layer with the reference picture list to induce a prediction sample with respect to the current block; inducing a recovery sample with respect to the current block based on the prediction sample and the prediction block with respect to the current block; and transmitting reference information for indicating a picture that can be used for interlayer prediction from the pictures of the reference layer.

Claim (Index 20):
A video decoding method by a video decoder, comprising:\n receiving flag information for whether a picture in a reference layer is not used for an inter-layer prediction; decoding and storing pictures in the reference layer; deriving an inter-layer reference picture for a current block from at least one of the decoded pictures in the reference layer based on the flag information; constructing a reference picture list comprising the inter-layer reference picture in the reference layer and a reference picture in the current layer; deriving a predicted sample of the current block in the current layer based on the inter-layer reference picture comprised in the reference picture list; deriving a reconstructed picture based on the predicted sample and a residual sample of the current block; and performing deblocking filtering on the reconstructed picture, wherein when the flag information indicates that a specific picture in the reference layer is not used for the inter-layer prediction, the specific picture is not comprised in the inter-layer reference picture set, and wherein the flag information is received through a slice segment header, and in all slice segment header of the picture in the reference layer, a value of the flag information is set to the same.
