A METHOD AND AN APPARATUS FOR ENCODING AND DECODING A SCALABLE VIDEO SIGNAL

摘要

A method for decoding a multilayer video signal according to the present invention includes the steps of: determining whether the corresponding picture of a lower layer is used as an interlayer reference picture of a current picture of an upper layer based on the time level identifier of the lower layer; and limitedly performing the interlayer prediction of the current picture based on a tile boundary arrangement flag which shows the tile arrangement state between the upper layer and the lower layer if the corresponding picture of the lower layer is used as the interlayer reference picture of the current picture of the upper layer.
