These
settings appear near the bottom of the SDI Signal submenu:
•
SMPTE 352 Payload ID Enable : Select the check box to enable the
SMPTE 352M Payload Identifier.
Note:
The SMPTE 352M payload identifier is a required element for a
compliant 3 Gb/s signal stream. The payload identifier is optional for SD and
HD formats.
•
Secondary Output : Use the drop- down list to select a Test Pattern or
a Black signal for the secondary BNC connector.
When set to the Test Pattern selection for channel 1, the SDI 1A and
SDI 1B connectors will output the same test signal. The same is true
for the channel 2 connectors when Test Pattern is set as the Secondary
Output selection for channel 2.
When set to the Black selection for channel 1, the SDI 1B Black signal
is the same format and sample structure as the SDI 1A output. The
same is true for the channel 2 connectors when Black is set as the
Secondary Output selection for channel 2.
•
Alpha Channel Data : This setting is active only when the sample
structure is set to “+A” for 3G signal formats. Selects the data to be
placed on the alpha channel when a sample structure that includes an
alpha channel is selected. The channel can contain a duplicate of the Y
or G channel data or a flat field signal. Use the drop - down list to Copy
of Y/G Channel or select a 0% to 100% Flat Field in 10% increments.
•
2xHD Stream Content : This setting is active only when the signal
format is set to 2×HD. It selects the content for the first and second HD
signals on link A and link B. Use the drop - down list to select Test
Signal/Test Signal, Test Signal/Black, or Black/Test Signal.
SDI Configure Zoneplate Submenu
Use this submenu to configure the parameters of zone plate signals. These
settings become active when you select a zone plate signal for output from the
Signal Selection drop - down list. The information for each signal varies
depending on the individual zone plate signal.
The Configure Zoneplate submenu consists of three major sections: Zoneplate
Parameters, Video, and information that applies to all zone plate signals. For
more information on using zone plate signals, refer to the information later in
this document. (See , SDI Zone plate signals .)
