Abstract:
A motion information storing method and a TMVP deriving method using the motion information storing method are provided. The motion information storing method includes a step of determining a representative block out of blocks of a motion data storage unit in a co-located picture with a current picture and a step of storing motion information of the representative block as motion information of the motion data storage unit, wherein the motion information of the representative block is used as motion information of the blocks included in the motion data storage unit.

Claim (Index 37):
A non-transitory computer-readable storage medium storing encoded video data comprising information on instructions, when executed, causing a video decoding apparatus to perform operations comprising: determining a positioning pixel for a temporal motion vector predictor (TMVP) of a current block in a current picture; deriving a co-located prediction block (colPb) in a reference picture based on the positioning pixel; deriving the temporal motion vector predictor (TMVP) of the current block in the current picture based on a motion vector of the co-located prediction block (colPb) in the reference picture; and performing an inter prediction for the current block based on the temporal motion vector predictor (TMVP) derived based on the motion vector of the colPb in the reference picture, wherein the co-located prediction block (colPb) is a prediction block covering a modified location that is determined based on a location of the positioning pixel, and wherein the positioning pixel is determined as a pixel at a right-bottom side among central four pixels located at the center of a co-located block in the reference picture, wherein the co-located block is a block having a same position and size as the current block and located in the reference picture.
