    Abstract: A method and an apparatus for designating and decoding inter-layer reference video are provided to improve coding efficiency by allowing different blocks existing in one current video to refer to blocks of different lower-layer video when a layer of video to be currently encoded or decoded is a spatial upper layer. An MB(Macro-Block) searching part hierarchically searches one or more lower-layer video of input video and searches an MB in the lower-layer video which corresponds to each MB in the input video. An MB descriptor inserting part inserts an MB descriptor, which is information for describing lower-layer video including the searched MB, into the MB in the input video which corresponds to the searched MB. An adaptive reference part refers to each MB in one or more lower-layer video described by the MB descriptor.

    Abstract: A reference slice removal alarm device and a method thereof are provided to perform encoding without an error when attempting hierarchical switching to a lower layer which is remained after removal by informing an alarm. A receiver(310) receives a scalable video stream including reference information as information related to a discardable layer. A removing unit(320) removes the discardable layer based on the reference information if a network status is deteriorated than a first standard value. A reference information updating unit(330) updates the reference information by adding information, about which discardable layer is removed according to at least one or more upper layer and a base layer of the scalable video stream, to the reference information.
