itrary scale factor chosen to make the third coordinate of Rec. ITU-T H.264 (01/2012) cP[ i] equal to 1. The elements of A[i], R[i], T[i] are determined according to the syntax elements signalled in this SEI message and as specified below. num_views_minus1 shall be equal to the value of the syntax element num_views_minusl in the active MVC sequence parameter set for the coded video sequence. The value of num_views_minusl shall be in the range of 0 to 1023, inclusive. intrinsic_param_flag equal to 1 indicates the presence of intrinsic camera parameters. intrinsic_param_flag equal to indicates the absence of intrinsic camera parameters. extrinsic_param_flag equal to 1 indicates the presence of extrinsic camera parameters. extrinsic_param_flag equal to 0 indicates the absence of extrinsic camera parameters. intrinsic_params_equal equal to 1 indicates that the intrinsic camera parameters are equal for all cameras and only one set of intrinsic camera parameters are present. intrinsic_params_equal equal to 0 indicates that the intrinsic camera parameters are different for each camera and that a set of intrinsic camera parameters are present for each camera. prec_focal_length specifies the exponent of the maximum allowable truncation error for focal_length_x[i] and focal_length_y[i as given by 2-prec_focal_length The value of prec_focal_length shall be in the range of 0 to 31, inclusive. prec_principal_point specifies the exponent of the maximum allowable truncation error for principal_point_x[i] and principal_point as given by 2-prec_principal_point The value of rec_principal_p shall be in the range of 0 to 31, inclusive. prec_skew_factor specifies the exponent of the maximum allowable truncation error for skew factor as given by -prec_skew_factor The value of prec_skew_factor shall be in the range of 0 to 31, inclusive. sign_focal_length_x|i] equal to 0 indicates that the sign of the focal length of the i-th camera in the horizontal direction is positive. sign_focal_length_x[i equal to 1 indicates that the sign is neg
