Claim 10:
11. A system comprising:
memory configured to store computer program code; and
at least one processor configured to receive at least one coded video stream, access the computer program code, and operate as instructed by the computer program code, the computer program code comprising:
decoding code configured to cause the at least one processor to decode a coded picture from the at least one coded video stream, the decoding code comprising determining code configured to cause the at least one processor to determine a picture type of the coded picture based on:
a first “nal_unit_type” syntax element that indicates a first video coding layer (VCL) network abstraction layer (NAL) unit type of a first VCL NAL unit of a first slice of the coded picture, and a second “nal_unit_type” syntax element that indicates a second VCL NAL unit type of a second VCL NAL unit of a second slice 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,

wherein the first VCL NAL unit type is different from the second VCL NAL unit type.
