1. a kind of video decoding apparatus, comprising:

  • Extractor, information and multiple offsets from bit stream parsing about the method for determining the pixel group that will be compensated;

    Restore pixel compensation device, the value for restoring pixel is mended by using the offset determined according to each pixel groupIt repays, wherein restore pixel and is divided into each pixel group,Wherein, when determining pixel group according to band based on the information about the method for determining pixel group, restore the total of the value of pixelRange is equally divided into band, restores pixel and is divided into the pixel group according to band, restores pixel compensation device by using rootThe value for restoring pixel is compensated according to the offset of each pixel group of band,Wherein, when determining pixel group according to marginal value rank based on the information about the method for determining pixel group, restore pixelIt is divided into the pixel group according to marginal value rank, restores pixel compensation device by using each pixel according to marginal value rankThe offset of group compensates the value for restoring pixel.
