摘要： A method of processing a video signal includes obtaining a transform coefficient of a current block from a bitstream according to a predetermined scanning order, determining an intra prediction mode of the current block on the basis of the transform coefficient, and performing intra prediction on the current block using the intra prediction mode and a neighboring sample adjacent to the current block.
