Method and device for processing video signal by using adaptive color space transform

Abstract

Abstract The present invention relates to a method and a device for processing a video signal, the method 5 comprising the steps of: acquiring, from a bitstream, a transform skip active flag indicating whether a transform skip flag can transform skip is applied to exist in a transform unit syntax, the flag indicating whether a transform skip a transform block included in a current 10 block; acquiring, from the bitstream, a palette active flag indicating whether a palette mode is applied; when the transform skip active flag indicates existence of the transform skip flag in the transform unit syntax or the palette active flag indicates application of the palette mode, acquiring, from the bitstream, information related to a minimum quantization parameter which is allowed in a transform skip mode; acquiring the minimum quantization parameter on the basis of the information related to the minimum quantization parameter; correcting a quantization 15 20 parameter on the basis of the acquired minimum quantization parameter; and reconstructing the current block on the basis of the corrected quantization parameter. 5 20 26 21 07 22 29 J ul 2 02 6 2 9 J u l 2 0 2 6 2 0 2 6 2 1 0 7 2 2
