Commands Example Response Control
Rule:
<rule-value> can take on the
following values, and tells the card
which incoming aspect ratio
information to use:
0x01: AFD -> Fill -> Default
0x02: AFD -> Default
0x04: Fill -> Default
0x08: Default
No other values will be accepted by
the card, no combinations are
available.
Insert:
The <insert -value> can be any
binary combination of the following
values:
0x02: WSS Extended
0x04: WSS
0x08: SMPTE352
0x10: Video Index
0x20: AFD
Note that the value 0x01 is not
currently supported, and that the card
therefore will only accept even
numbers as <insert-values>.

<croffset> Video processing block
Gain and offset must be given as
floating point numbers. Gain is limited
to [0, 4> for luma and chroma, while
offsets are limited to <-1024, 1024>
for luma and <-512, 512> for chroma.

<samples> sps Video delay
This sets the minimum video delay of
the card.
In info this block reports back the
current delay in nanoseconds. This
will vary with the incoming video
standard.

<audio_samples>
sps Audio delay
The audio delay is given in audio
samples. Audio delay is always given
relative to video.

If lines != 0 the resulting phase will
vary with incoming video standard,
see dly 0 above.

mcbar | (flat <Y>
<Cb> <Cr>) ) Internal video generator.
The video generator will be activated
in two different ways: If selected as a
fallback option the generator will
generate the selected pattern when
the other input(s) are missing, and
then use the video settings from the
last external source present. It can
also be selected as the main input in
cho 1, in which case its own video
settings will also be used. cbar
denotes colorbar, while mcbar
