Abstract: An apparatus for processing a video signal and method thereof are disclosed. The present invention includes receiving prediction mode information, interpolating information and a residual of a current block, reconstructing an interpolating pixel using the interpolating information and a neighbor block, and reconstructing the current block using the interpolating pixel, the prediction mode information and the residual, wherein the interpolating information is generated based on a location of the current block. According to an apparatus and method for processing a video signal, high reconstruction rate can be obtained by improving the related art method having limited intra prediction modes available for a current block located on a boundary area of a picture in encoding in a manner of reconstructing and using an interpolating pixel based on interpolating information.

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。

Abstract: A method for context-modeling coding information of a video signal for compressing or decompressing the coding information is provided. An initial value of a function for probability coding of coding information of a video signal of an enhanced layer is determined based on coding information of a video signal of a base layer.
