Abstract:
A method for decoding a video signal using a graph-based transform, the method being characterized by including the steps of: parsing a transform index from the video signal; obtaining context information for a target unit, where the context information includes a prediction mode for a current block or peripheral blocks; obtaining an inverse-transform kernel on the basis of at least one of the transform index and the context information; and performing an inverse transform for the current block using the inverse transform kernel.

Claim (Index 15):
An apparatus for decoding a video signal using a graph-based transform, comprising:\n a parsing unit parsing a transform index from the video signal; and an inverse transform unit obtaining context information for a target unit, obtaining an inverse transform kernel based on at least one of the transform index and the context information, and performing an inverse transform on the current block using the inverse transform kernel, wherein the context information comprises a prediction mode for a current block or a neighboring block.
