3.3.3 De-embedding
The audio channel with the data signal to be de-embedded must be configured by GYDA as
there may be several data channels available.
The AAV-HD-XMUX will automatically detect the data channel format when present and
output the data on the 8P8C Modular jack connector. The output driver will only be active
when data is output in UART mode. The means that the output is always active when raw
data is used.
3.3.4 Limitations
1. There is one thing the user must do in order to receive embedded data. The audio
source where the data is embedded must be routed to a destination in the stereo
router. This is because the extraction of the data takes place on the output of the
router.
Example: Data is to be de-embedded from embedded audio channels 1&2. Route
embedded audio channels 1&2 routed to output to Delay 4.
2. The normal UART mode checks the data when receiving and only embeds valid
bytes. The data format must be correct. This also means that a BREAK condition of
many spaces will not be detected or transmitted. Contact support if this is a
requirement.
