Vd_nLC_nLC
Codes: 5, 6, L, C,
x, ni
SDI1 & SDI2 Demux Channel Chrominance and Luminance
Status.
n - video standard, 6 for a 625 input and 5 for a 525 input
L - Active Luminance is shown by ‘L’ or ‘x’ for dark or near
dark values – signal peaks below 12.5% of Peak White.
C - Active Chrominance is shown by ‘C’ or ‘x’ for
monochrome or near monochrome values – chroma peaks less
than 12.5% Saturation.
Example: Vd_6LC__ni, SDI 1 is 625 with significant
Luminance and Chrominance content, but SDI2 is absent.
Note:
The continued presence of ‘x’ values for Chrominance or Luminance may indicate an
error condition, such as no picture or lack of colour.
