The Insertion pulldown is used to enable/disable the insertion of Dolby Metadata, and to specify the source:
•
OFF
no embedding. Incoming audio metadata in the HD input will pass through to the output.
•
From ABUS
embed metadata from an external card connected on the ABUS (A1 only).
•
Fixed PCM
embed default PCM metadata using the specified Dialnorm value.
The Dialnorm pulldown is enabled when Fixed PCM is selected in the Insertion pulldown, and allows
selection of the Dialog Normalization Value for embedded PCM data:
•
Available selections are [-20, -22, -24, -26, -27, -28, -30, -31] dB
The Status Indicator turns green when Dolby metadata has been detected within an HD input signal.
Namedropper
tab
A green button indicates the presence of Namedropper on line 18 for SD inputs. The same indication is used
for HD inputs if a compliant Namedropper ANC packet is present.

Config
area
Presence:
The status indicator turns Green when AFD is detected on the input signal. On an SD input, the
AFD presence will indicate the presence of the selected AFD source only, i.e. AFD, VLI or WSS (for 625
sources only)
Source:
Selects the source of AFD information – options are AFD (SMPTE 2016), VLI of WSS (for 625
sources only).
Insertion Line:
The Insertion line is used to select on which line in the VANC the AFD packet (SMPTE 2016)
will be inserted. It is not necessary to specify the detection line since the card will automatically detect the
incoming packet.
Insertion:
The Insertion pull-down menu is used to enable or disable the insertion of AFD on the two outputs:
•
On the HD output, the Ancillary Aspect Ratio packet will be inserted
•
For SD outputs, a selection must be made when enabling insertion:
o
525 outputs – AFD (SMPTE 2016) or VLI
o
625 outputs – AFD (SMPTE 2016), VLI or WSS
