METHOD AND APPARATUS FOR SLICE COMMON INFORMATION SHARING Russian patent published in 2016 - IPC H04N19/82 H04N19/174 

FIELD: physics, computer engineering.

SUBSTANCE: invention relates to computer engineering. A method of sharing information in a video decoding system, the method comprising receiving a first information-sharing flag in picture level data or sequence level data; if the first information-sharing flag indicates sharing, determining common information of an loop filter corresponding to a sample adaptive offset (SAO) filter or an adaptive loop filter (ALF) in the picture level data or the sequence level data, wherein said common information comprises partial filter parameters of the loop filter, which include one filter coefficient of the ALF or at least one offset value of the SAO; determining filter information of the loop filter for one or more slices of a picture, wherein a portion of the filter information is determined from said common information; and applying the ALF using at least one filter coefficient in the common information or applying the SAO using at least one offset value in the common information to one or more slices of the picture.

EFFECT: eliminating redundancy of common information in a slice header.
