5.6.6 Standard Presets When No Aspect Signaling
If no input aspect signaling is available and the conversion required is always from a known
input aspect ratio to another known input aspect ratio, one of the standard presets may be
selected. The presets are sub-divided into SD to SD cross conversion, SD to HD/3G up
conversion, and HD/3G to SD down conversion.
5.6.6.1
SD Input is 702
SD Input is 702 is an additional ARC preset mode, which is available for incoming content
that uses a 702 sample line rather than a 720 sample line. If the incoming content uses a 702
sample line, select the check box. This introduces an additional H scaling factor of 720/702,
resulting in a slight horizontal stretch.
This control only has an effect on SD inputs.
5.6.6.2
SD Output is 702
SD Output is 702 is an additional ARC preset mode, which is available for outgoing content
that requires a 702 sample line rather than a 720 sample line. If the outgoing content requires
a 702 sample line, select the check box. This introduces an additional H scaling factor of
702/720, resulting in a slight horizontal squeeze.
This control only has an effect on SD outputs.
5.6.6.3
SD Cross Conversion
LB = letterbox, h-crop = horizontal crop, ana = anamorphic.
Note:
These presets are only active when the Aspect Signaling Control Enable check box is
deselected.
Note:
SD Input 702 introduces an additional h scaling factor of 720/702.
Note:
SD Output 702 introduces an additional h scaling factor of 702/720.
