Audio Embedding Modes
The audio embedder component in the HMX6801
+
B2/C2 and
HMX6801
+
B4/C4 is composed of several smaller subcomponent
blocks:
• One ancillary data stripper (ADS)
• Two 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 two 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.
The audio embedding modes are G1EmbMode and G2EmbMode .
Table 3-1 briefly describes the Off , Append , OverWrt , and Auto
options available from each of the embedding modes.
Table 3-1. Embedding Mode Options
Options Description
Off Disables embedding of the selected audio group
Append Attempts to insert the audio data and control packets
immediately following the last existing audio data/control
packet in the horizontal ancillary region
(This setting is valid only if the audio group to be
embedded does not already exist.
See Figure 3-1 on page 25 and Figure 3-2 on page 26 for
more information on Append embedding mode.
