    • 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.
    • 提供了一种用于指定和解码层间参考视频的方法和装置,以便当要当前编码或解码的视频层时,通过允许存在于一个当前视频中的不同块来指代不同下层视频的块来提高编码效率 是一个空间上层。 MB(宏块)搜索部分分级地搜索输入视频的一个或多个下层视频,并且搜索与输入视频中的每个MB对应的下层视频中的MB。 MB描述符插入部分将用于描述包括搜索到的MB的下层视频的信息的MB描述符插入到与搜索到的MB对应的输入视频中的MB中。 自适应参考部分是指由MB描述符描述的一个或多个下层视频中的每个MB。
