摘要： A method for deriving a motion vector predictor of a current block, by a decoding apparatus or an encoding apparatus, comprises deriving a first motion vector predictor (mvp) candidate, wherein the first mvp candidate is derived based on a first motion vector of an available block among a bottom left block and a left block of the current block when there is the available block among the bottom left block and the left block; deriving a second mvp candidate, wherein the second mvp is derived based on a second motion vector of an available block among a top right block, a top block and a top left block of the current block when there is the available block among the top right block, the top block and the top left block; constructing a mvp candidates list based on at least one of the first mvp candidate and the second mvp candidate; and determining the motion vector predictor for the current block, wherein the motion vector predictor for the current block is selected from mvp candidates in the mvp candidates list.
The first mvp candidate is derived by scaling the first motion vector of the available block among the bottom left block and the left block when there is the available block, among the bottom left block and the left block, of which reference picture is different from a reference picture of the current block. In the deriving the second mvp candidate, scaling for the second motion vector is not available when there is the available block among the bottom left block and the left block and the scaling for the first motion vector is applied in the deriving the first mvp candidate.

摘要： A video decoding apparatus (200) comprises an entropy decoder (210) configured to obtain video information including picture reconstruction information and offset information from a bitstream, a predictor (230) configured to reconstruct a picture based on the picture reconstruction information and a filter (235) configured to apply an in-loop filter to the reconstructed picture. The filter (235) applies a deblocking filtering process to the reconstructed picture, and applies a sample adaptive offset (SAO) process to the reconstructed picture based on the offset information after completing process of the deblocking filtering. The offset information includes first offset information indicating whether the sample adaptive offset (SAO) process is enabled and second offset information for applying an offset to a sample when the first offset information indicates that the sample adaptive offset (SAO) process is enabled. The second offset information includes offset type information for specifying an offset type for the sample, wherein the offset type information indicates that a band offset is applied to the sample. The second offset information includes information on offset values for multiple bands. The second offset information includes start band information explicitly indicating a variable start of the multiple bands to determine together with end band information indicating a variable end of the multiple bands a band group comprising the multiple bands among 32 bands, wherein an offset value, corresponding to a band among the multiple bands is applied to the sample..

摘要： A method of decoding video data comprises (S310) deriving a motion vector predictor candidate of a current block from a neighboring block group based on a check order, wherein the neighboring block group includes a left neighboring block (A m ) and a bottom left neighboring block (A m+1 ). (S320) selecting the motion vector predictor of the current block (900) based on the motion vector predictor candidate, deriving a motion vector difference of the current block (900) based on received information on the motion vector difference, and (S330) deriving a motion vector of the current block (900) based on the selected motion vector predictor and the motion vector difference. The check order is determined as in order of the bottom left neighboring block (A m+1 ) to the left neighboring block (A m ). The step of deriving the motion vector predictor candidate is performed based on a first condition or a second condition, wherein the first condition is whether a block has a reference picture identical to that of the current block (900) and a reference picture list identical to that of the current block (900), wherein the second condition is whether a block has a reference picture identical to that of the current block (900) and a reference picture list different from that of the current block (900), wherein the first condition is checked before the second condition, and wherein when the bottom left neighboring block (A m+1 ) does not satisfy both the first condition and the second condition, it is checked whether the left neighboring block (A m ) satisfies the first condition or the second condition.
