Abstract: In one embodiment, the method includes predicting at least a portion of a current image in a current layer based on at least a residual coded portion of a base image in a base layer, a reference image, shift information for samples in the predicted current image, and offset information indicating a position offset between at least one boundary pixel of the reference image and at least one boundary pixel of the current image. The residual coded portion represents difference pixel data.

Abstract: A method and an apparatus of decoding a video signal are provided. The present invention includes the steps of parsing first coding information indicating whether a residual data of an image block in the enhanced layer is predicted from a corresponding block in the base layer, from the bitstream of the enhanced layer, and decoding the video signal based on the first coding information. And, the step of parsing includes the step of performing modeling of the first coding information based on second coding information indicating whether prediction information of the corresponding block in the base layer is used to decode the image block in the enhanced layer. Accordingly, the present invention raises efficiency of video signal processing by enabling a decoder to derive information on a prediction mode of a current block in a decoder instead of transferring the information to the decoder.

Abstract translation: 提供了解码视频信号的方法和装置。 本发明包括以下步骤：解码第一编码信息，该第一编码信息指示增强层中的图像块的残留数据是否从基本层中的相应块，从增强层的比特流预测，并且基于 第一编码信息。 而且，解析步骤包括基于指示基层中的相应块的预测信息是否用于对增强层中的图像块进行解码的第二编码信息来执行第一编码信息的建模的步骤。 因此，本发明通过使解码器得到关于解码器中的当前块的预测模式的信息而不是将信息传送到解码器来提高视频信号处理的效率。
