1. A method of processing video data, comprising:
determining, for a conversion between a current video block of a video and a bitstream of the video, a usage of an implicitly selected transform skip mode for the conversion of the current video block according to a rule, wherein the rule specifies that the usage is based on a number of representative coefficients in the current video block; and
performing the conversion based on the determining,
wherein in the implicitly selected transform skip mode, a prediction residual between the current video block and a reference video block is presented in the bitstream without applying a transformation, and
wherein the usage of the implicitly selected transform skip mode for the current video block is based on a parity of the number of the representative coefficients.
