Abstract:
The present invention relates to an image information encoding and decoding method and a device for same. One embodiment of an image information encoding method according to the present invention, as an image information encoding method according to another embodiment of the present invention, includes the steps of: generating a restore block; applying a deblocking filter on the restore block; applying a Sample Adaptive Offset (SAO) on the restore block having the deblocking filter applied thereon; and transmitting information on the SAO application. During the applying of the SAO, the SAO is applied to chroma pixels, and during the transmitting of the information, in addition to information on whether the SAO is applied on the chroma pixels, at least one of area information, division information on the SAO coverage area, SAO type information, and SAO offset information is transmitted.

Claim (Index 37):
A non-transitory computer-readable storage medium storing a bitstream generated by performing:\n deriving a prediction sample in a current picture based on inter prediction or intra prediction; deriving a residual sample in the current picture based on the prediction sample; generating a reconstructed picture of the current picture based on the prediction sample and the residual sample; applying a deblocking filtering process to the reconstructed picture; applying a sample adaptive offset (SAO) process to at least one of a luma sample or a chroma sample in the reconstructed picture after completing the deblocking filtering process; and encoding video information including prediction information on the prediction sample, residual information on the residual sample, and offset information for the sample adaptive offset process, wherein the offset information includes first flag information indicating whether the sample adaptive offset process is enabled for the luma sample and second flag information indicating whether the sample adaptive offset process is enabled for the chroma sample, wherein the offset information includes band information indicating one of 32 bands as a starting band of a band group consisting of n bands among the 32 bands, the band group is specified based on the starting band, wherein the offset information include offset value information representing offset values for the n bands, and wherein an offset value corresponding to a band among the n bands is applied to the luma sample or the chroma sample, wherein n is a positive integer.
