Abstract
A video coding mechanism is disclosed. The mechanism includes receiving a bitstream comprising a plurality of sub-pictures associated with a picture and a flag. The sub-pictures are contained in a plurality of video coding layer (VCL) network abstraction layer (NAL) units. A NAL unit type value is the same for all VCL NAL units associated with the picture when the flag is set to a first value. When the flag is set to a second value, a first NAL unit type value for VCL NAL units containing one or more of the sub-pictures of the picture is different than a second NAL unit type value for VCL NAL units containing one or more of the sub-pictures of the picture. The sub-pictures are decoded based on the NAL unit type values. The sub-pictures are forwarded for display as part of a decoded video sequence.
