Abstract: An apparatus and method for deciding an adaptive noise level for bandwidth extension are provided. The apparatus includes a noise level decider for deciding a high-band noise level for bandwidth extension according to tonality of an input signal, a pitch frequency analyzer for detecting a pitch frequency of the input signal and analyzing correlation between the detected pitch frequency and a frequency channel, and a noise level controller for adaptively controlling the decided high-band noise level based on the analyzed correlation of the pitch frequency and the frequency channel.

Abstract: An apparatus and method for adapting 2D and 3D stereoscopic video signal. The apparatus for adapting 2D and 3D stereoscopic video signal provides a user with the best experience of digital contents by adapting the digital contents to a particular usage environment including the user characteristic and terminal characteristic. The apparatus allows the efficient delivery of video contents associated with user's adaptation request.

Abstract: A segment-based contour encoding method is provided. A motion compensation of an object in a current image with respect to a reference image is performed to obtain a motion-compensated image. The contour contained in the image motion-compensated is compared with a contour of an object in a current image, to divide the whole contour of the object in the current image into a global motion compensated (GMC) segments and a global motion compensation failure (GMF) segments. Each GMF segments is divided into a local motion compensated (LMC) segment and a local motion compensation failure (LMF) segment. The GMC segments and the LMC segments are motion-compensation-encoding and the LMF segments are encoded using only pixel information constituting each LMF segment. The contour encoding method can reduce the number of the LMF segments and can perform an efficient encoding operation for motion compensation encoding.
