the tone map information applies to the current decoded picture only. tone_map_repetition_period equal to 1 specifies that the tone map information 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 tone mapping information SEI message with the same value of tone_map_id is output having PicOrderCnt() greater than PicOrderCnt( CurrPic ). tone_map_repetition_periodequal to 0 or equal to 1 indicates that another tone mapping information SEI message with the same value of tone_map_id may or may not be present. tone_map_repetition_period greater than 1 specifies that the tone map information persists until any of the following conditions are true: A new coded video sequence begins. A picture in an access unit containing a tone mapping information SEI message with the same value of tone_map_id is output having PicOrderCnt() greater than PicOrderCnt( CurrPic ) and less than or equal to PicOrderCnt( CurrPic + tone_map_repetition_period. tone_map_repetition period greater than 1 indicates that another tone mapping information SEI message with the same value of tone_map_i shall be present for a picture in an access unit that is output having PicOrderCnt() greater than PicOrderCnt(CurrPic and less than or equal to PicOrderCnt( CurrPic) + tone_map_repetition_period; unless the bitstream ends or a new coded video sequence begins without output of such a picture. coded_data_bit_depth specifies the BitDepthy of the luma component of the coded video sequence. It is used to identify the tone mapping information SEI message that is intended for use with the coded video sequence. If tone mapping information SEI messages are present that have coded_data_bit_depth that is not equal to BitDepthy, these refer to the hypothetical result of a transcoding operation performed to convert the coded video to the BitDepthy corresponding to the value of coded_data_bit_depth. The value of coded_data_bit_depth shall be in the range of 8 to 14, inclus
