Abstract:
A method for image decoding, according to the present invention, includes the following steps: receiving image information including a plurality of filter coefficients; generating a restored block for a current block on the basis of the image information; and applying an adaptive loop filter to the restored block on the basis of the plurality of filter coefficients. According to the present invention, image encoding efficiency may be improved, arid complexity may be reduced.

Claim (Index 15):
A video decoding apparatus, comprising:\n an entropy decoding module configured to obtain prediction information for a prediction process and offset information for a sample adaptive offset (SAO) process from a bitstream; a prediction module configured to derive prediction samples based on the prediction information; an adder configured to generate a reconstructed picture based on the prediction samples; and a filtering module configured to apply an in-loop filtering process to the reconstructed picture, wherein for the in-loop filtering process, the filtering module applies a deblocking filtering process to the reconstructed picture, and applies the SAO process to a sample in the reconstructed picture on which the deblocking filtering process is completed, wherein the offset information includes offset type information indicating that a band offset type is applied to the sample, wherein the offset information includes information on n offset values, and wherein the offset information includes explicit band information indicating one of 32 bands as a starting band of a band group consisting of n bands, and an offset value corresponding to a band among the n bands is applied to the sample, wherein n is an integer.
