The bitstream was created using the VTM-12.3 encoder with changes to signal DPB parameters, levels and different bitrates and CPB sizes for temporal sublayers.

Bitstream feature:
The bitstream is for testing temporal scalability with HRD signalling for temporal sublayers.
It has 5 temporal sublayers with a GOP size of 16 and HRD signalling (including buffering period and picture timing SEI message with timing for temporal sublayers). The following encoding structure was used:

GOPSize                       : 16          # GOP Size (number of B slice = GOPSize-1)
