Claim Text:
1. A video decoding apparatus using an inter-prediction, the apparatus comprising: a decoder configured to reconstruct a flag and quantized transform coefficients by decoding a bitstream, the flag indicating one among a plurality of modes for determining the motion vector of the current block; a predictor configured to determine a motion vector of a current block to be decoded in a current picture, and predict pixels in current block using the motion vector of the current block; an inverse quantizer and inverse transformer configured to inversely quantize and then inversely transform the quantized transform coefficients to thereby reconstruct residual signals; and an adder configured to add the predicted pixels to the reconstructed residual signals which correspond to the predicted pixels, wherein, when the flag indicates a first mode among the plurality of modes, the predictor is configured to
