1. A method of decoding a coded video bitstream implemented by a video decoder, comprising:
receiving, by the video decoder, the coded video bitstream, wherein the coded video bitstream comprises a coded video sequence (CVS) including a gradual decoding refresh (GDR) access unit, wherein the GDR access unit contains a plurality of video coding layer (VCL) network abstraction layer (NAL) units for a GDR picture, each of the plurality of VCL NAL units for the GDR picture has a GDR NAL unit type (GDR_NUT); and
starting, by the video decoder, decoding of the CVS from the GDR picture, wherein the GDR picture has a temporal identifier (ID) equal to zero, and wherein the GDR picture is a first picture in the CVS or a GDR period.
