Claim 18:
19. The non-transitory computer-readable recording medium of claim 17, wherein the format rule specifies that a value of a fourth syntax element in a sequence parameter set (SPS) is inferred to be 0 when a value of a second general constraint flag is equal to 1;
wherein the value of the fourth syntax element being 0 indicates that a GDR (gradual decoding refresh) picture is disabled and not present in a coded layer video sequence (CLVS) referring to the SPS, and the value of the second general constraint flag being equal to 1 indicates that a constraint of not using GDR is imposed on a network abstraction layer (NAL) unit;
wherein the fourth syntax element is gdr_enabled_flag, and the second general constraint flag is no_gdr_constraint_flag; and
wherein the format rule specifies that a value range of a fifth syntax element included in a sequence parameter set (SPS) which indicates a bit depth of samples of luma and chroma arrays is constrained by a third general constraint flag, and a value of the third general constraint flag which is in a range of 0 to 8.
