Apparatus and method for generating/recovering motion information based on predictive motion vector index encoding, and apparatus and method for image encoding/decoding using same
Disclosed is a video encoding apparatus includes: an intra prediction unit to generate a prediction block by using adjacent pixels of a current block to be encoded; an inter prediction unit to (1) generate index information of a predictive motion vector of the current block based on motion vectors of blocks adjacent to the current block and a motion vector of a co-located block of a reference frame, (2) generate motion information of the current block including predictive motion vector index and reference frame index together with a differential motion vector obtained by subtracting the predictive motion vector from a motion vector of the current block, and (3) generate a prediction block based on the generated motion information; and an encoding unit configured to encode a residual block by using a subtraction unit and a transform and quantization unit to thereby generate a bitstream.
