Audio Test
Tones
Table 3-1 describes the frequency and levels of each audio output test tone, available as a
selection from each of the Output Ch ( 1–16 ) Source Select and Audio Procamp AES
(1A-8B) Out Source parameters (see page 68).
Group (1-4) Deembedding Control
Table 3-2 describes options for the Group (1–4) Deembedding Control parameter (see
page 57).
Audio
Embedding
Modes
The audio embedder component in the SFS6803
+
and OP
+
SFS
+
is composed of several
smaller subcomponent blocks:

One ancillary data stripper (ADS)

Four audio embedding subcomponents
The first subcomponent is an ancillary data stripper (ADS). This block removes all ancillary
data packets in the input SDI stream, prior to embedding.
Following the ADS block are four separate audio-embedding subcomponents. Each
subcomponent has the ability to operate on only one audio group, either appending or
overwriting a predetermined group onto the SDI stream.

Item Description
Repeat Upon detection of a de-embedding error, the
de-embedder repeats the last good AES
sample.
Mute Upon detection of a de-embedding error, the
de-embedder mutes the current outgoing AES
sample.
