The audio embedder component in the HMX6800+BC8 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.
