ies the RGB sample value in the coded data that maps to the maximum value in the signalled target_bit_depth. It is used in combination with the min_value parameter. All values in the coded data that are larger than or equal to max_value are mapped to this maximum value in the target_bit_depth representation. sigmoid_midpoint specifies the RGB sample value of the coded data that is mapped to the centre point of the target_bit_depth representation. It is used in combination with the sigmoid_width parameter. Rec. ITU-T H.264 (01/2012) sigmoid_width specifies the distance between two coded data values that approximately correspond to the 5% and 95% values of the target_bit_depth representation, respectively. It is used in combination with the sigmoid_midpoint parameter and is interpreted according to the following function: (D-28) where f(i) denotes the function that maps an RGB sample value i from the coded data to a resulting RGB sample value in the target_bit_depth representation. start_of_coded_interval[ i ] specifies the beginning point of an interval in the coded data such that all RGB sample values that are greater than or equal to start_of_coded_interval[ i ] and less than start of coded interval[ + 1] are mapped to i in the target bit depth representation. The value of start_of_coded_interval[ is equal to coded_bit_depth The number of bits used for the representation of the start of coded interval (coded_data_bit_depth+7): >> 3 ) << 3. num pivots specifies the number of pivot points in the piece-wise linear mapping function without counting the two default end points, (0, coded_pivot_value[ specifies the value in the coded_data_bit_depth corresponding to the i-th pivot point. The number of bits used for the representation of the coded_pivot_value is ( (coded_data_bit_depth+7)> << 3. target_pivot_value[ i specifies the value in the reference target_bit_depth corresponding to the i-th pivot point. The number of bits used for the representation of the target_pivot_value is target_bit_depth -7) << 3. D.2.25 Fram
