oint in the current coded video sequence. t1 is the removal time (in seconds) of the current access unit, and t2 is the removal time (in seconds) of the last access unit (in decoding order) of the current coded video sequence. With X specifying the value of avg_bitrate[ ], the following applies. If t1 is not equal to t2, the following condition shall be true. (H-12) Otherwise (t1 equal to t2), the following condition shall be true. (x&(24-1))==0 (H-13) max_bitrate[ specifies the maximum bit rate of the representation of the current operation point, given by BitRateBPS(max_bitrate_layer_representation[i]), in bits per second, with the function BitRateBPS() being specified in Equation H-11. The maximum bit rate of the representation of the current operation point is calculated based on a time window specified by max_bitrate_calc_window[i] max_bitrate_cale_window[ specifies the length of the time window, in units of 1/100 second, based on which bitrate[ i is calculated. constant_frm_rate_idei] specifies whether the frame rate of the representation of the current operation point is constant. If the value of avg_frm_rate as specified below is constant whichever a temporal section of the operation point representation is used for the calculation, the frame rate is constant, otherwise the frame rate is non-constant. constant_frm_rate_idc[i) equal to 0 specifies that the frame rate is not constant, constant_frm_rate_idc[i equal to 1 specifies that the frame rate is constant, and constant_frm_rate_idc[i equal to 2 specifies that the frame rate may be or may not be constant. The value of constant_frm_rate_idc[i]s shall be in the range of 0 to 2, inclusive. avg_frm_rate[i specifies the average frame rate, in units of frames per 256 seconds, of the representation of the current operation point. The semantics of avg_frm_rate[i] is identical to the semantics of average_frame_rate in sub-sequence layer characteristics SEI message when accurate_statistics_flag is equal to 1, except that herein the set of NAL units in the range o
