1 + max_bitrate_calc_window[ i] / 100, and bTotal is the number of bits in all NAL units of the current scalable layer representation that belong to access units with a removal time greater than or equal to t1 and less than t2. With X specifying the value of max_bitrate_layer_representation| i ], the condition specified in Equation G-373 shall be obeyed. max_bitrate_calc_window[ ] specifies the size of the time window that is used for calculating the upper bounds for the bit rate of the current scalable layer (indicated by max_bitrate_layer[i]) and the bit rate of the current scalable layer representation (indicated by max_bitrate_layer_representation[i in units of 1/100 second. Rec. ITU-T H.264 (01/2012) constant_frm_rate_ide[i indicates whether the frame rate of the current scalable layer representation is constant. In the following, a temporal segment tSeg is any set of two or more consecutive access units, in decoding order, of the current scalable layer representation, fTotal( tSeg ) is the number of frames, complementary field pairs, and non-paired fields in the temporal segment tSeg, t1 tSeg ) is the removal time (in seconds) of the first access unit (in decoding order) of the temporal segment tSeg, t2( tSeg ) is the removal time (in seconds) of the last access unit (in decoding order) of the temporal segment tSeg, and avgFR( tSeg ) is the average frame rate in the temporal segment tSeg, which is given by: avgFR( tSeg) == Round( fTotal( tSeg ) *256:(t2(tSeg)-t1(tSeg))) (G-374) the current scalable layer representation does only contain one access unit or the value of avgFR( tSeg ) is constant over all temporal segments of the scalable layer representation, the frame rate is constant; otherwise, the frame rate is not constant. constant_frm_rate_idc[i] equal to 0 indicates that the frame rate of the current scalable layer representation is not constant. constant_frm_rate_idc[i equal to 1 indicates that the frame rate of the current scalable layer representation is constant. constant_frm_rate_idc[ ] equal to
