    摘要: 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 to store a reference image; a template motion estimation unit 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 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 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 to entropy encode the quantized differential image and to output an image stream.

    摘要: An image contents service system includes a first encoder encoding an original image data into a first-layer data, and a second encoder modulized to encode the original image data into a second-layer data by referencing the first-layer data, whereby image contents upgraded more than the first-layer data are provided. Accordingly, the image contents service system can minimize the waste of frequency bands and resources of an encoding system in the upgrade, and can provide a multiple quality contents service.

    摘要: Provided are a color video scalability encoding and decoding method and a device thereof. The color video scalability encoding method includes encoding a chrominance image block of an enhancement layer by using lower layer information. In the encoding a chrominance image block, a color coded block pattern value is generated according to a pattern of quantization coefficients of a residual chrominance Image block chrominance image block generated using the lower layer information.
