Video decoding device and video decoding method |
摘要 |
A video decoding device includes: a decoder that decodes an encoded video bit stream to generate a prediction error signal; a motion compensator that performs a motion compensation prediction using a motion vector that refers at least one picture to generate a motion compensation prediction signal; a weighted predictor that generates a weighted prediction signal from a linear sum of (1) a product of the motion compensation prediction signal and a first weighting coefficient and (2) a second weighting coefficient; a selector that selects one of the motion compensation prediction signal and the weighted prediction signal; and an adder that adds (1) selected one of the weighted prediction signal and the motion compensation prediction signal and (2) the prediction error signal.
