11.2.3 Legalization
All color video signals are ultimately coded as RGB for display on a picture monitor. The
Legalizer ensures that the output video stays within the legal RGB gamut limit, making it
suitable for the broadcast signal chain. To achieve this, the legalizer reduces the gain equally
on all channels.
The level the legalizer scales down to is selected using the radio buttons. Anything in the
RGB space above the selected level is scaled down to that level. Anything in the RGB space
below 0 mV is clipped to 0 mV. This is a good compromise between minimizing hue change
and raising apparent brightness.
Legalizer choices are:
•
Off (Default)
•
700mV
•
721mV
•
735mV
•
746mV
11.2.4 Test Patterns
The Test Patterns list enables you to choose the type of pattern displayed on the output
picture. You can choose from Off, Black, Ramp, and Bars.
11.2.5 Blanking
•
Embedded Audio:
•
Enable
(Default): enables embedded audio
•
Blank:
removes embedded audio
•
SD Half Line:
•
Pass
(Default): enables source half lines
•
Blank:
will blank the source half lines. This can be useful for certain ARC
settings, for example, SD16:9AN to SD4:3 Fit to Width
11.2.6 Default Output
On input signal loss, select “black” to set output to black (default), or “pattern” to set output to
the test pattern. See section 11.2.4 for selection of the test pattern.
Note:
If the test pattern has been set to black, then if default output is chosen to be “pattern”, the
output will go to black on input loss.
