There are provided scalable video encoders, scalable video decoders, and corresponding scalable video encoding and decoding methods. A scalable video encoder includes an encoder for encoding a block in an enhancement layer of a picture by using a motion vector that corresponds to a block in a lower layer of the picture as a motion vector predictor for the block in the enhancement layer, and using a weighting parameter that was applied to a particular lower layer reference picture to encode the block in the lower layer for motion compensation of the block in the enhancement layer. The block in the enhancement layer corresponds to the block in the lower layer.
