Claim Text:
1. An apparatus for video decoding, the apparatus comprising: a processor which is configured for determining a motion vector predictor of a current block among predictor candidates including a motion vector predictor candidate according to a collocated block of the current block; and a memory which is configured for storing a picture reconstructed by inter prediction using the determined motion vector predictor of the current block, wherein: when prediction of the collocated block is available by using a reference list L0 of the collocated block, the processor is configured for determining the motion vector predictor candidate using an L0 motion vector of the collocated block corresponding to a reference picture determined from the reference list L0 of the collocated block, when prediction of the collocated block is available by using a reference list L1 of the collocated block, the processor is configured for determining the motion vector predictor candidate using an L1 motion vector of the collocated block corresponding to a reference picture determined from the reference list L1 of the collocated block, when prediction of the collocated block of the current block is available by using the reference list L0 of the collocated block and prediction of the collocated block is available by using the reference list L1 of the collocated block, and when reference pictures of the current block are to be output prior to a current picture including the current block, the processor is configured for determining the motion vector predictor candidate using a motion vector corresponding to a reference list of the current block, selected among the L0 motion vector of the collocated block according to the reference list L0 and the L1 motion vector of the collocated block according to the reference list L1, wherein the reference list of the current block is at least one of a reference list L0 of the current block and a reference list L1 of the current block.
