scalable video stream decoder and scalable video stream generator

摘要

Scalable Video Stream Decoder and Scalable Video Stream Generating Device The present invention relates to a scalable video stream generating apparatus according to the present invention which classifies encoded images into various streams. encoded image based on whether the encoded images are to be used as reference frames, and designates different identifiers for the various encoded image streams. a scalable video stream decoding apparatus according to the present invention (i) receives the various encoded image streams generated by the scalable video stream generating apparatus according to the present invention, (ii) rearranges, in decoding order, encoded images included in at least one extracted encoded image stream based on the identifiers assigned to the various encoded image streams, and (ii) decodes the encoded images thus reordered. thus, it is possible to provide a scalable video stream system having a simple arrangement.
