Abstract: As for scalable video encoding, an interlayer texture prediction, an interlayer motion information prediction, and an interlayer residual signal prediction are used in order to remove the redundancy in an interlayer image. According to the present invention, in order to improve the accuracy of the interlayer prediction, a block that is most similar to a sample of the current target block as well as a reference layer block corresponding to a current target block may be used as an prediction signal. In addition, in the interlayer prediction, a weighted sum of a prediction signal obtained from an interlayer image to which the current target block pertains and a prediction signal obtained from the reference layer image may be used a prediction signal.

Abstract: 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.
