1. A method of video processing, comprising:
performing a conversion between a video comprising one or more pictures and a bitstream of the video according to a format rule, wherein the format rule specifies that, in response to satisfying one or more conditions, a syntax element indicating whether a first syntax structure providing level information and a second syntax structure providing decoded picture buffer information are present in a sequence parameter set is set to be equal to 1 to indicate that the first syntax structure and the second syntax structure are present in the sequence parameter set, and wherein the syntax element equal to 1 further specifies that a third syntax structure providing general timing information related with hypothetical reference decoder parameters and a forth syntax structure providing output layer set timing information related with hypothetical reference decoder parameters are allowed to be present in the sequence parameter set.
