1. A method performed by at least one processor, the method comprising:
receiving a first video coding layer (VCL) network abstraction layer (NAL) unit of a first slice of a coded picture and a second VCL NAL unit of a second slice of the coded picture, the first VCL NAL unit having a first VCL NAL unit type and the second VCL NAL unit having a second VCL NAL unit type that is different from the first VCL NAL unit type; and
decoding the coded picture, the decoding comprising determining a picture type of the coded picture based on:
a first “nal_unit_type” syntax element that indicates the first VCL NAL unit type of the first VCL NAL unit of the coded picture, and a second “nal_unit_type” syntax element that indicates the second VCL NAL unit type of the second VCL NAL unit of the coded picture, wherein the first “nal_unit_type” syntax element and the second “nal_unit_type” syntax element have different values from each other, or
an indicator, received by the at least one processor, indicating that the coded picture includes VCL NAL units that respectively have “nal_unit_type” syntax elements with different values from each other.
