    摘要: A video encoding method and apparatus and video decoding method and apparatus to generate a restored image having a minimum error with respect to an original image. The video decoding method includes: parsing offset merge information indicating whether offset parameters of a current block and at least one neighboring block from among blocks of video are identical to each other from a received bitstream; restoring an offset type and offset values among the offset parameter of the current block based on the offset merge information; determining an edge class or a pixel value band of a restored pixel based on an edge type or a pixel value band type of the current block indicating the offset type; and determining an offset value corresponding to the edge class or the pixel value band of the restored pixel from the offset values and adjusting a pixel value of the restored pixel according to the offset value.

    摘要: A video decoding apparatus for preventing overflow from occurring in output data in operations of a decoding process. The video decoding apparatus includes units for parsing and restoring quantized transformation coefficients in units of blocks of an image from a received bitstream, restoring transformation coefficients by performing inverse quantization and a first clipping on the quantized transformation coefficients, and restoring samples by performing one-dimensional (1D) inverse transformation and a second clipping on the inverse-quantized transformation coefficients, and generating residual values by performing horizontal inverse-transformation on the sample values. The first clipping is performed for restricting the inverse-quantized transformed coefficients to a range of a first bit depth and the second clipping is performed for restricting the sample values to a range of a second bitdepth.
