    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.
