摘要：
There are provided scalable video encoder and 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 applying a same weighting parameter to an enhancement layer reference picture as that applied to a lower layer reference picture used for encoding a block in a lower layer of the picture. The block in the enhancement layer corresponds to the block in the lower layer, and the enhancement layer reference picture corresponds to the lower layer reference picture. The scalable video decoder includes a decoder for decoding a block in an enhancement layer of a picture by applying a same weighting parameter to an enhancement layer reference picture as that applied to a lower layer reference picture used for decoding a block in a lower layer of the picture. The block in the enhancement layer corresponds to the block in the lower layer, and the enhancement layer reference picture corresponds to the lower layer reference picture.
