 the deblocking filter process specified in clause 8.5.14 rather than the cropped result of the deblocking filter process specified in clause 8.7. Otherwise, the frame buffer is considered to use one frame buffer of DPB capacity for its storage. When dec_frame_buffering_constraint_flag is equal to 1, the frame buffering capacity used by all of the frame buffers in the DPB that contain pictures, as derived in this manner, shall not be greater than Max( 1, max_dec_frame_buffering) during the operation of the HRD for the coded video sequence. The value of dec_frame_buffering_constraint_flag shall be the same in all deblocking filter display preference SEI messages of the coded video sequence. deblocking_display_preference_repetition_period specifies the persistence of the deblocking filter display preference SEI message and may specify a picture order count interval within which another deblocking filter display preference message or the end of the coded video sequence shall be present in the bitstream. The value of deblocking_display_preference_repetition_period shall be in the range 0 to 384, inclusive. deblocking_display_preference_repetition_period, equal to 0 specifies that the deblocking filter display preference SEI message applies to the current decoded picture only. deblocking_display_preference_repetition_periodequal to 1 specifies that the deblocking filter display preference SEI message persists in output order until any of the following conditions are true: A new coded video sequence begins. A picture in an access unit containing a deblocking filter display preference SEI message is output having PicOrderCnt() greater than PicOrderCnt( CurrPic ). deblocking_display_preference_repetition_period greater than 1 specifies that the deblocking filter display preference SEI message persists until any of the following conditions are true: A new coded video sequence begins. A picture in an access unit containing a deblocking filter display preference SEI message is output having PicOrderCnt() greater than PicOrd
