Grass Valley AMX-3981 2014 - Manual (Page 30)

GUIDE TO INSTALLATION AND OPERATION
24 | AMX-3981
• The table has two tabs, one for SD inputs, and one for HD inputs.
• The table in each tab lists all possible Input AFD flags for that format, and beside each is a Replacement AFD
pulldown list that also lists all possible AFD flags.
• If the Replacement AFD does not match the Input AFD, the Replacement AFD
name is colored, so that it is immediately obvious which AFDs will be substituted.
Note: AFD substitution is ignored when no source flag is detected at the input. In this case, the Default flag is used.
5.3.3.3 Error and Warning Messages (SD only)
During SD operation, situations may arise when a conflict has occurred or may occur due to the enabling of certain
metadata parameters such as time code insertion, SMPTE 2016/VLI insertion, or Dolby Metadata insertion.
• A warning message will appear at the bottom of the Metadata / AFD panel.
• See for an example.
Here is a list of all possible messages that may be displayed and a description of the error or potential conflict.
“Dolby Metadata/VLI line insertion conflict. Refer to the user manual.” [Error in red]
This error occurs when the AMX-3981 has been programmed to generate Dolby Metadata and VLI on the same
line. The VLI signal is placed on line 14 for 525 and line 11 for 625. Make sure to select a different line number for
Dolby Metadata insertion.
“AFD insertion may overwrite incoming TC on insertion line. Refer to the user manual.” [Warning in blue]
Incoming DVITC time code may unknowingly be replaced by the insertion of SMPTE 2016 AFD flag. In order to
avoid any problems, make sure the line number of any incoming time code is known.
“Dolby Metadata insertion may overwrite incoming TC/VLI on insertion line. Refer to the user manual.” [Warning in
blue]
Incoming DVITC time code or VLI signal may unknowingly be corrupted by the insertion of Dolby Metadata. In
order to avoid any problems, make sure the line number of any incoming time code is known. If Dolby Metadata is
inserted on line 14 in 525 or line 11 in 625, make sure no time code or VLI is present in the input video signal.
“Dolby Metadata insertion may overwrite incoming TC on insertion line. Refer to the user manual.” [Warning in blue]
Incoming DVITC time code may unknowingly be corrupted by the insertion of Dolby Metadata. In order to avoid
any problems, make sure the line number of any incoming time code is known.
“Dolby Metadata/AFD insertion may overwrite incoming TC on insertion line. Refer to the user manual.” [Warning in
blue]
Incoming DVITC time code may unknowingly be replaced by the insertion of Dolby Metadata or the SMPTE 2016
AFD flag. In order to avoid any problems, make sure the line number of any incoming time code is known.
“VLI insertion may overwrite incoming Dolby Metadata on insertion line. Refer to the user manual.” [Warning in blue]
Incoming Dolby Metadata may unknowingly be corrupted by the insertion of the VLI flag. In order to avoid any
problems, make sure no Dolby Metadata is present on line 14 in 525 or line 11 in 625 when VLI is inserted.
5.4 Audio Processing panel
The Audio Processing panel provides full audio processing and delay parameters for up to 32 channels. The first 16
channels come from the embedded input channels. The second set of 16 channels comes from the output channels of
the following modules:
