This contribution documents syntax designs for HRD syntax subsequent to BoG discussions (see BoG report notes J0550). The HRD syntax is claimed applicable to both the HEVC base specification for temporal scalability and potential future HEVC extensions. If HRD parameters remain as part of VUI, the syntax structure hrd_parameters( ) would present in the VUI syntax. Otherwise, the syntax structure hrd_parameters( ) would not be present in the VUI syntax.

In the review of the first version of this document, the following changes were agreed.

• 
  If put in VUI, there should be a presence flag.
  
• 
  The loop should include fixed_pic_rate_flag, cbr_flag[SchedSelIdx], low_delay_hrd_flag.
  
• 
  Add pic_duration_in_tc_minus1 to adjust frame rate in each layer.
  
• 
  For sub-ticks, define tick_divisor_minus2 (8b).
  
• 
  Remove time_offset_length (editorial).
