    • A method and apparatus for scalably encoding and decoding a video signal is provided. During encoding, prediction is performed on an image block to produce residual data of the image block, and the residual data of the image block is selectively coded into a residual difference from residual data of a block of a base layer, which spatially corresponds to the image block and is present in a base layer frame temporally coincident with a frame including the image block. Whether to code the image block into the residual difference is determined based on the difference between coding information (motion vectors or block pattern (CBP) information) of the image block and coding information of the corresponding block. Separate information indicating whether or not the image data has been coded into the residual difference is not transmitted to the decoder even if the image data has been coded into the residual difference.
    • 提供了一种用于可视地编码和解码视频信号的方法和装置。 在编码期间,对图像块执行预测以产生图像块的残差数据,并且将图像块的残差数据有选择地编码为与基本层的块的残留数据的残差,其与空间上对应于 并且存在于与包括图像块的帧在时间上重合的基本层帧中。 基于图像块的编码信息(运动矢量或块图案(CBP)信息)与相应块的编码信息之间的差异来确定是否将图像块编码为残差。 即使将图像数据编码为残差,也不会将表示图像数据是否被编码为残差的分离信息发送到解码器。

    • In one embodiment of a method of decoding a first frame sequence layer, at least one motion vector of an image block in a frame of the first frame sequence layer is determined based on scaling a motion vector for an image block in a frame of a second frame sequence layer. The motion vector for the image block in the frame of the second frame sequence layer is scaled based on a display size difference between frames in the second frame sequence layer and frames in the first frame sequence layer. A display size of frames in the second frame sequence layer is different than a display size of frames in the first frame sequence layer, and the second frame sequence layer does not include a frame temporally coincident with the frame of the first frame sequence layer. The image block in the frame of the first frame sequence layer is decoded based on the determined motion vector.
    • 在对第一帧序列层进行解码的方法的一个实施例中,基于对第二帧序列层的帧中的图像块的运动矢量进行缩放来确定第一帧序列层的帧中的图像块的至少一个运动矢量 帧序列层。 基于第二帧序列层中的帧与第一帧序列层中的帧之间的显示大小差异,对第二帧序列层的帧中的图像块的运动矢量进行缩放。 第二帧序列层中的帧的显示尺寸不同于第一帧序列层中的帧的显示大小,并且第二帧序列层不包括与第一帧序列层的时间上一致的帧。 基于所确定的运动矢量对第一帧序列层的帧中的图像块进行解码。
