Abstract
In a method and a device for encoding or decoding an image according to the present invention, motion information for bidirectional prediction of a current block may be derived on the basis of an inter mode previously defined in the device for encoding or decoding an image, and inter prediction may be performed on the current block on the basis of the motion information, wherein the motion information for bidirectional prediction is adjusted to be motion information for unidirectional prediction according to the predefined inter mode.
Claims10
A method of decoding an image, the method comprising:
- deriving motion information for bidirectional prediction of a current block, based on an inter mode pre-defined in an image decoding apparatus;
- and
- performing inter prediction on the current block based on the motion information,
- wherein, according to the pre-defined inter mode, the motion information for the bidirectional prediction is adjusted to motion information for unidirectional prediction.
