1. A method of determining an encoding mode, comprising:

  • performing motion estimation of a macro block in an inter16×

    16 mode, an inter16×

    8 mode, and an inter8×

    16 mode;

    determining whether to further perform motion estimation in a P8×

    8 mode;

    according to the determination result, omitting or performing motion estimation in the P8×

    8 mode and then selecting one mode from among the modes for which motion estimation has been performed; and

    omitting or further performing spatial prediction encoding according to a rate-distortion cost of the selected mode and determining a final encoding mode.
