    摘要: Provided are a scalable video encoding/decoding method and apparatus, which may improve an image quality of a base layer while not using an anti-aliasing filter. The scalable video decoding apparatus includes an entropy decoding unit to decode an image received from an encoding apparatus, a de-blocking filter to reduce a block distortion of the decoded image, a motion compensation unit to apply a motion compensation scheme to an image passing through the de-blocking filter, a half-pel filter to apply a half-pel compensation scheme to an image where the motion compensation scheme is applied by the motion compensation unit, and an output unit to output an image where the half-pel compensation scheme is applied by the half-pel filter.

    摘要: A scalable video decoder and a controlling method thereof are provided. A method of controlling a scalable video decoder includes: determining whether a macro block mode of an upper layer is an interlayer prediction mode when decoding a scalable video; when the macro block mode of the upper layer is determined as the interlayer prediction mode, determining an up-sampling operation is required to thereby either perform texture up-sampling using corresponding macro block information of a lower layer and neighboring pixel information, or perform residual up-sampling using the corresponding macro block information of the lower layer; and decoding the upper layer using the texture up-sampling or the residual up-sampling.
