Computer processor hardware receives image data specifying element settings for each image of multiple original images in a sequence. The computer processor hardware analyzes the element settings across the multiple original images. The computer processor hardware then utilizes the element settings of the multiple original images in the sequence to produce first encoded image data specifying a set of common image element settings, the set of common image element settings being a baseline to substantially reproduce each of the original images in the sequence.

A video decoding method includes obtaining split information indicating whether to split a current block, splitting the current block into two or more lower blocks when the split information indicates to split the current block, obtaining encoding order information indicating an encoding order of the lower blocks of the current block, determining a decoding order of the lower blocks according to the encoding order information, and decoding the lower blocks according to the decoding order.

Different implementations are described, particularly implementations for video encoding and decoding are presented including a method for deblocking an image. According to an implementation, in a method for deblocking an image, at least one boundary is determined between a first block of samples and a second block of samples; a boundary strength is determined according to at least one of a prediction mode of the first block and a prediction mode of the second block; and samples of the first and second blocks neighboring the at least one boundary are filtered according to the boundary strength. Advantageously, in case the prediction mode of the first block is a weighted prediction mode, the boundary strength further depends on the relative weight of samples used in predicting the first block of samples according to the weighted prediction mode of the first block and reciprocally for the second block.

Computer processor hardware receives settings information for a first image. The first image includes a set of multiple display elements. The computer processor hardware receives motion compensation information for a given display element in a second image to be created based at least in part on the first image. The motion compensation information indicates a coordinate location within a particular display element in the first image to which the given display element pertains. The computer processor hardware utilizes the coordinate location as a basis from which to select a grouping of multiple display elements in the first image. The computer processor hardware then generates a setting for the given display element in the second image based on settings of the multiple display elements in the grouping.

A filtering method by a decoding device according to the present invention comprises the steps of: receiving information relating to ALF control depth; deciding an ALF control unit on the basis of information relating to the division depth and the ALF control depth of a current block in a restoration picture with respect to a current picture; determining whether or not ALF is applied to the current block in an ALF control unit level; and, if the ALF is determined to be applied to the current block, performing the ALF for the current block. In the filtering method, the current picture is recursively divided on the basis of a QTBT structure, and the current block is one of blocks divided on the basis of the QTBT structure.
