    • There are provided scalable video encoder and decoders, and corresponding scalable video encoding and decoding methods. A scalable video encoder includes an encoder (100) 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 (200) 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.
    • 提供了可扩展的视频编码器和解码器,以及相应的可扩展视频编码和解码方法。 一种可分级视频编码器包括:编码器(100),用于通过将相同的加权参数应用于增强层参考图像来对图像的增强层中的块进行编码,所述增强层参考图像应用于用于对较低层块中的块进行编码的下层参考图像 图层的图层。 增强层中的块对应于下层中的块,并且增强层参考图片对应于下层参考图片。 可分级视频解码器包括:解码器(200),用于通过对与增强层参考图像相同的加权参数应用相同的加权参数来解码图像的增强层中的块,所述增强层参考图像应用于用于对较低层 图层的图层。 增强层中的块对应于下层中的块,并且增强层参考图片对应于下层参考图片。
