A macroblock using the same motion vector with the central macroblock is regarded as a part of the face and is quantified with a smaller quantization parameter.
与中央宏块使用相同运动矢量的宏块被视为脸的部分，以较小的量化参数对其进行量化。

The efficient video coding technique finds out a motion vector of a central macroblock, and detects whether the motion vector can be applied to other macro blocks in the video frame.
