Abstract

Official abstract text for this publication.

A video encoding method and apparatus, and a video decoding method and apparatus for generating a reconstructed image having a minimized error between an original image and the reconstructed image. The video decoding method accompanied by a sample adaptive offset (SAO) adjustment, the method includes: obtaining 5 slice SAO parameters with respect to a current slice from a slice header of a received bitstream; obtaining luma SAO use information for a luma component of the current slice and chroma SAO use information for chroma components thereof from among the slice SAO parameters; determining whether to perform a SAO operation on the luma component of 10 the current slice based on the obtained luma SAO use information; and equally determining whether to perform the SAO adjustment on a first chroma component and a second chroma component of the current slice based on the obtained chroma SAO use information.

First claim

Opening claim text (preview).

The invention claimed is: 1. An apparatus for video decoding, the apparatus comprising at least one processor which implements: a parser configured to obtain slice offset information indicating whether to apply an offset according to an offset type for a current slice, and a sample compensator configured to compensate for samples of a current block among blocks included in the current slice, by using an offset parameter of the current block, wherein: when the slice offset in…
