ARC Mode
Select from Bypass, Anamorphic 25%, Panels/Letterbox 25%, Crop 25%, 14:9, Flex Wide and Custom.
Bypass will scale the image to full screen.
Crop 25% makes a 4:3 fit a 16:9 by chopping off top and bottom; or makes a 16:9 fit a 4:3 by chopping
off (25% off) left and right.
Anamorphic 25% is for 4:3 SD outputs only, it linearly compresses a 16:9 image into 4:3 without
cropping or added bars.
Panels/Letterbox 25% will add bars (25% vertically in total) above and below for a 16:9 image on a 4:3
SD output, or add bars (25% horizontally in total) at the sides of a 4:3 image on a 16:9 output.
14:9 will crop part of the sides of a 16:9 image to make it 14:9 and scales it to fit horizontally on a 4:3 SD
output. This will add small bars on top and bottom. For a 4:3 image the bottom and top will be cropped
to make it 14:9 and scales it to fit vertically on a 16:9 output. This will add bars to the sides.
Flex Wide is applying a non-linear stretch horizontally to convert a 4:3 into 16:9 with the emphasize of
aspect ratio conversion in the center of the image.
Custom allows user to specify a zoom horizontally and/or vertically starting with full screen scaling.
Note: Some aspect ratio selections will have no visible effect on the displayed image for certain input
and output mode combinations, e.g. if the input and output formats have the same aspect ratio letter
boxing and cropping have the same effect as bypassing.

ARC Custom
H Crop/Side Panels and V Crop/Letterbox Panels
When ARC mode is set to Custom this menu becomes available. The output image can be further
scaled up and down individually in horizontal and vertical direction. When shrinking black bars are
added to the non-used panel region.

Processing Mode
Best Picture
Noise reduction and motion-adaptive de-interlacing operate in this mode to give the best quality picture.
There is optional MPEG noise reduction for SD interlaced inputs. Typical latency is 5-8 frames, worst
case is 9 frames. Exact latency depends on whether the input is progressive or interlaced which noise
reduction filters are enabled and whether frame synchronisation is enabled. Motion compensated frame
rate conversion also adds extra latency.
Low Latency
In this mode noise reduction and motion-adaptive de-interlacing are disabled which allows the delay
through the unit to be reduced to 3 frames in free run mode or 2 frames when frame synchronising.
4.9.8.
3G-SDI Data Map
SP-14 allows to convert and output 3G-SDI video in various formats which are 10 Bit 4:2:2 or 10 Bit
4:4:4 component video, 10 Bit 4:4:4 RGB and 12 Bit 4:4:4 X’Y’Z’. For 1080p50, 59.94 and 60Hz modes
either Level A or B transport scheme can be set.
4.9.9.
Blue Check
The live video output image blue, green, red and white (luma) content can be separated and displayed
individually when selecting the respective component through this menu.
4.9.10.
Safe Area Markers
Safe area markers will show a maximum window of the output image with the format set up under this
menu. Available aspect ratios are 4:3, 14:9 and 16:9.
