1. A motion vector encoding apparatus comprising:

  • a predicted motion vector selector for selecting an optimal predicted motion vector from a candidate motion vector set of a current block;

    a prediction mode determiner for determining a motion vector prediction mode of the current block with a selected motion vector prediction mode from a plurality of motion vector prediction modes based on a decision criterion prearranged with a motion vector decoding apparatus; and

    an encoder in dependence on a determined motion vector prediction mode from the prediction mode determiner, for determining the optimal predicted motion vector or a default predicted motion vector into a predicted and determined motion vector for a current motion vector, encoding a differential vector between the current block and the predicted and determined motion vector, and selectively encoding and outputting the determined motion vector prediction mode as an encoded motion vector prediction mode depending on the determined motion vector prediction mode.
