    摘要: An apparatus and method for adapting a scalable video coding (SVC) bitstream is provided. The apparatus may include: a layer selection unit to select at least one quality layer from a plurality of quality layers contained in each of spatial layers of the SVC bitstream; a layer discarding unit to discard the at least one quality layer; and a layer dependency modification unit to modify a quality layer dependency between one or more quality layers remaining among the plurality of quality layers, or a spatial layer dependency between the plurality of spatial layers. Accordingly, it is possible to adapt the SVC bitstream where the entire quality of spatial layers is enhanced.
