Abstract

Disclosed is an apparatus for decoding motion information in merge mode. The apparatus for decoding motion information in merge mode discloses a merge mode motion vector decoding unit configured to generate motion information using available spatial and temporal merge candidates when a motion information encoding mode of a current block indicates a merge mode; a prediction bock generating unit configured to generate a prediction block of the current block using motion information; and a residual block generating unit configured to perform an entropy-decoding process and an inverse-scanning process on residual signals to generate a quantized block, and to perform an inverse-transforming process on the quantized block to generate a residual block. Furthermore, a reference picture index of the temporal merge candidate is set to 0, a motion vector of the temporal merge candidate is selected among a first merge candidate block and a second merge candidate block based on a position of the current block within a slice or a largest coding unit, and the motion vector of the second merge candidate block is selected as the motion vector of the temporal merge candidate if the current block is …
