Video DAC
The module can handle 50Hz- and
60Hz-
based sources, but can’t
convert video material between these
time bases. The user must therefore
select two modulations, one for
50Hz-based sources and one for
60Hz-based sources.
The (on | off) immediately following
the wss auto is a status telling if the
WSS bits are currently in use.

Error detection and handling
Error counting. The count itself is
reported in info. Errors can be
masked off and not counted; this is
the purpose of the mask. The counter
itself is 16b and will wrap around, but
can also be reset by issuing reset.

Audio matrix
mtx 0 (size 10:10) controls the audio
matrix; outputs 0-7 are embedded
sound, 8=adac and 9=AES.
Note: Any combination of the three
basic commands are allowed, for
instance the following command to
set up a 10x10 audio matrix in a
single line:
mtx 3 1 1 2 2 3 0,3-9
=> mtx 3 size 10:10 3 1 2 3 3 3 3 3 3

use when default scaling is selected.

Audio generator
The amplitude of the generated sine
that can be chosen as fallback in
audio change-overs. Legal values are
-180cBFS or -200cBFS (centiBel
referred to full scale output). Units
are optional, but if included must be
written as cBFS (case sensitive).

Audio processing
one block for each output from cho 2-
11. Outputs 8+9 are adac and AES,
the lower 8 are routed to the
embedder. The meaning of the
commands are as follows:
lr = Normal
rl = Channel swapped
ll = Left channel to both output
