6.6.2. Selecting the Audio Groups That Will Be Embedded

The down converter card has two embedders that each insert one group of audio on the serial digital video
output. The source for Embedder A is the audio selected by the De-embedder A menu item and the
source for Embedder B is De-embedder B menu item. There are two controls that set the audio groups
where the embedders will put the audio on the serial digital output. For simplicity, only one control will be
shown in the manual.

Group 1
Group 2
Group 3
Group 4

6.6.3. Selecting the Audio Delay

Audio
Audio Delay
+/- 100.0 ms
Under normal conditions the settings for de-embedder A and de-embedder
B should be different otherwise the audio will be repeated on the SD SDI
output.
The default for De-embedder A is group 1 and the default group for De-
embedder B is group 2.
With these controls, you can set the destination group for Embedder A and
B.
When set to Off, the embedder will be disabled.
Otherwise the embedder destination can be set to a specific group.
The group for Embedder A must be different from Embedder B. If the user
sets them the same then the next higher group number will be used for
Embedder B.
This control adjusts the audio delay +/- 100 ms from the nominal delay
necessary to match the card's video processing delay.
Note: Negative values are limited to the amount of video delay that causes
the delay to be only the audio processing delay. The card does not have
negative delay capability.
