Operation
34
Set the embedding mode to
Auto
.
If the group is present, it will be overwritten; if it is not present, it will be appended. The
overwrite and append errors are actually warnings that the operation is not being
performed.
In SD-SDI mode, do not overwrite embedded groups of 20-bit audio samples with
groups of 24-bit audio samples.
The required extended data packet information appended to that group may overwrite
a pre-existing audio group. For 24-bit audio embedding, use the
ADS Clean
feature
provided.
Mono Channel Audio Embedding
To embed audio on a channel-by-channel (mono) basis, preserving some embedded audio
channels while replacing others from external AES sources, follow these steps:
1
Configure the input audio routing path (Input > Audio > Routing) by selecting audio pair
sources to the individual audio sample rate converters.
By default, SRCs 1-8 are assigned to the 8 deembedded audio sources
(DMX Grp1 Ch1/
2, DMX Grp1 Ch3/4, DMX Grp2 Ch1/2,
etc.) and SRCs 9-16 are assigned to the
external AES audio sources (
AES1a/1b, AES2a/2b
, etc.).
2
Configure the output audio routing path (Output > Audio Source Select > Embedded
Audio) by selecting sources to each mono embedded audio output channel.
Each SRC (
SRC1a, SRC1b, SRC2a,
etc.) can be selected to any output embedded audio
channel, allowing for any input-to-output audio configuration.
3
Remove or preserve existing embedded audio with the
ADS Clean
parameter (Processing >
Audio).
4
Use the
Audio Group (1-4) Embedding Mode
parameters (Processing > Audio >
Embedding) to select the desired audio group embedding mode for each audio group.
In
Auto
mode, non-existing audio groups are appended and existing audio groups
are overwritten.
In
Overwrite
mode, the original audio is preserved using the settings in step 2.
In
Off
mode, audio groups are untouched unless the
ADS Clean
parameter is
enabled.
Example: Replacing Audio Channel 1 in Group 1 Only
To replace
only
embedded audio channel 1 in group 1 with audio from external AES 1A
source, follow these steps:
1
Leave the input audio routing path at the default configuration (SRCs 1-8 from
deembedded audio, SRCs 9-16 from external AES audio).
2
Route the output audio sources as follows (Output > Audio Source Select > Embedded
Audio):
Output Emb Ch 1 Source Select: SRC9a
Output Emb Ch 2 Source Select: SRC1b
Output Emb Ch 3 Source Select: SRC2a
Output Emb Ch 4 Source Select: SRC2b
3
Preserve existing embedded audio by setting the
ADS Clean
parameter (Processing >
Audio) to
No
.
