Abstract:
1. A method for modeling coding information of a video signal performed by a video coding system, comprising: performing a modeling of first coding information based on second coding information, the first coding information indicating whether a residual data of an image block in an enhanced layer is predicted by using a residual data of a corresponding block in a base layer, the 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, the prediction information including prediction mode, partition information and motion information, the prediction mode including intra mode and inter mode, the motion information including a motion vector and a reference index, wherein the modeling comprises: deriving a context index increment of the first coding information based on a context index offset for the first coding information and the second coding information; and deriving an initial value of a probability coding function based on the context index increment.
