del (off | (on
<del12> <del34>)) Audio embedder block
en/dis: Enables or disables the
embedding of the group into the
ancillary area.
acp on/off: This is valid only for SD
and enables the audio control
package.
use24 on/off: This is only valid for
SD and selects between 24bit and
20bit sound.
del off/on delay12 delay34: For
each of the embedder groups the
delay bits for ch1+2 and for ch3+4
can be inserted into the ACP. The
delay value can be positive and
negative and is put directly into the
ACP as it is written.
Note: To set both delays to 0 would
be the same as turning the delays off.
The response reflects this.

iN 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:

iN Video output matrix
mtx 1 (size 2:2) controls the video
output switches.
0: Through mode (re-clocked only)
1: Processed mode (SDI from FPGA)

GPIs mapped to scalings
mtx 4 (size 17:16) controls how the 4-
bit GPI values are mapped to the 16
available scalings. The 12 fixed
scalings are 0-11, the 4 user scalings
are 12-15. The 17
th option is to not
perform any action
mtx 5 mtx 5 mtx 5 size 37:1 10
Active scaling
mtx 5 (size 16:1) tells which scaling is
currently used. No commands
