Abstract:
A method of encoding a video is provided, the method includes: determining a filtering boundary on which deblocking filtering is to be performed based on at least one data unit from among a plurality of coding units that are hierarchically configured according to depths indicating a number of times at least one maximum coding unit is spatially spilt, and a plurality of prediction units and a plurality of transformation units respectively for prediction and transformation of the plurality of coding units, determining filtering strength at the filtering boundary based on a prediction mode of a coding unit to which pixels adjacent to the filtering belong from among the plurality of coding units, and transformation coefficient values of the pixels adjacent to the filtering boundary, and performing deblocking filtering on the filtering boundary based on the determined filtering strength.

Claim (Index 3):
A non-transitory computer-readable medium for recording a bitstream, the bitstream comprising:\n information about a size of a maximum coding unit to be split from a picture; first split information for splitting hierarchically the maximum coding unit into one or more coding units; partition type information for one or more prediction units determined in the coding unit, wherein the partition type information indicates one of a symmetric type and an asymmetric type; second split information for splitting the coding unit into one or more transform units; and quantized transformation coefficients of the one or more transform units determined in the coding unit; wherein decoding process performed by a decoding apparatus based on the bitstream comprises: performing prediction on the one or more prediction units in the coding unit and inverse-transformation on the one or more transform units in the coding unit, in order to generate reconstructed pixels of the coding unit; when a boundary included in the coding unit corresponds to at least one of a boundary of the one or more prediction units and a boundary of the one or more transform units, determining a boundary strength for the boundary based on at least one of non-zero transformation coefficients, prediction mode, a motion vector, and a reference index; determining a deblocking filtering method including at least one of a number of filter-taps and a location of reconstructed pixels to be deblocking-filtered, based on at least one of the boundary strength and reconstructed neighboring pixels adjacent to the boundary; performing deblocking filtering of at least one of the reconstructed neighboring pixels according to the deblocking filtering method, in order to generate deblocking-filtered pixels of the coding unit; and determining a reconstructed picture including the deblocking-filtered pixels, wherein: when the first split information indicates a split for a current depth, a coding unit of a current depth is split into coding units of a lower depth, independently from neighboring coding units, and when the first split information indicates a non-split of a current depth, the one or more prediction units are obtained from the coding unit of the current depth and the one or more transform units are obtained from the coding unit of the current depth, wherein the determining of the boundary strength comprises determining the boundary strength based on whether a prediction mode of a coding unit to which the reconstructed neighboring pixels belong is an intra mode or an inter mode, and wherein the deblocking filtering is performed according to the deblocking filtering method when the boundary is not a boundary of the picture.
