Title:

VIDEO ENCODING METHOD USING IN-LOOP FILTER PARAMETER PREDICTION AND APPARATUS THEREFOR, AND VIDEO DECODING METHOD AND APPARATUS THEREFOR

Document Type and Number:

WIPO Patent Application WO/2016/017937

Kind Code:

A1

Abstract:

A video encoding apparatus according to an embodiment comprises: an encoding unit for generating encoded video data by encoding an input video; a decoding unit for decoding video data to apply a filter for correcting a value of a pixel from the encoded video data; an adaptive loop filter (ALF) parameter prediction unit for generating an ALF filter parameter for applying an ALF filter, which corrects a value of a current pixel using a value of an adjacent pixel located around the current pixel and a filter coefficient for the adjacent pixel, using information of the decoded video; a sample adaptive offset (SAO) filter unit for applying a SAO filter, which corrects a value of a current pixel using at least one of an edge offset and a band offset, to the decoded video data; an ALF filter unit for applying the ALF filter to video data to which the SAO filter is applied, using the ALF filter parameter; and an entropy encoding unit for performing entropy encoding of the ALF filter parameter.
