Chapter 3: Operation
•
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).
