1. A method of coding video data, the method comprising:
determining, by a processor implemented in circuitry, whether to code a network abstraction layer (NAL) initial arrival delay syntax element of a bitstream partition initial arrival time supplemental enhancement information (SEI) message of a bitstream including the video data based on whether NAL hypothetical reference decoder (HRD) parameters are coded for the bitstream;
in response to determining to code the NAL initial arrival delay syntax element, coding, by the processor, the NAL initial arrival delay syntax element;
determining, by the processor, independently of determining whether to code the NAL initial arrival delay syntax element, whether to code a video coding layer (VCL) initial arrival delay syntax element of the bitstream partition initial arrival time SEI message of the bitstream including the video data based on whether VCL HRD parameters are coded for the bitstream; and
in response to determining to code the VCL initial arrival delay syntax element, coding, by the processor, the VCL initial arrival delay syntax element.
