5.3.5 Legalization
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 in RollCall. 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
5.3.6 SFP Output Routing
In a dual-channel product that has SFP TX connectors, the source of the SFP output can be
either channel 1 or channel 2. The SFP outputs are only available in products variants that
have an SFP connector rear panel. If the rear panel has no SFP connector, the output option
is hidden.
•
SFP Source 1 and 2:
Selects the source, either channel 1 or channel 2, for SFP 1
and SFP 2 if they are transmit ports.
Note: SFP Source 1 and 2 can be set from either the Output-Ch1 or Output-Ch2
screen – any change in one screen is reflected in the other. See page 40.
5.3.7 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.
Note:
The SFP input selections will appear grayed out if either no SFP module or an unsupported
SFP module is inserted in the rear panel connector.
