    Abstract: Provided is an apparatus and method for encoding and decoding a video signal. A video signal encoding apparatus may include: a reference image storage unit (160) to store a reference image; a template motion estimation unit (170) to estimate a motion between an input image and the reference image using a template, and to generate motion estimation information; an adaptive motion compensation unit (180) to generate a predicted image using the motion estimation information and the reference image, to calculate a filter coefficient with respect to the predicted image using the template, and to filter the predicted image using the filter coefficient; a transformation and quantization unit (120) to perform integer-transformation and quantization for a differential image that is a difference between the input image and the filtered predicted image; and an entropy encoding unit (130) to entropy encode the quantized differential image and to output an image stream.

    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.
