cho 17 pos man 1 size 2 man k Video DAC output select
This change over has only manual
mode and works as a simple 2:1
switch.

1: Processed mode (from FPGA)
cho 18 pos man <k> cho 18 pos man 0
cho 18 pos man 1 size 2 man k Audio embedding enable for SD
This change over has only manual
mode and works as a simple 2:1
switch.
0: embedding off (Audio embedded
on input signal left untouched)
1: Embedding on

cho 19 pos man 1 size 2 man k Color space conversion on/off
0: no conversion
1: color space conversion from HD to

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.

one permanently assigned to each
incoming group, always enabled. No

scale 0 asp <aspect_ratio> out
<video_standard>
asp <aspect> Set down-converter aspect ratio.
Supported aspect ratios at the
moment are “16/9”, “16/9lb” and
“4/3”. Video standard output from the
scaler block is also included (576/25i
or 486/29i, selected based on
incoming video standard). Video
standard information is duplicated in
info.
Note: converter is always present
and active. The user must use cho
