Overview
The UDC-163 is a high quality 10-bit, HD down-converter with SD pass-through and individual aspect
ratio converter (ARC) controls for HD and SD inputs. The UDC-163 bridges SMPTE 292 high
definition (HD) and 259M-C standard definition (SD) signal formats; allowing high density and low
power conversion of HD signals.
The UDC-163 will down-convert HD to SD serial component digital and analog composite video. This
unit can re-aspect the image with separate rules for HD vs. SD inputs and adds 3:2 pull-down to 23.98
p/sF or i inputs. In addition, reticule overlays, for full aperture and safe area, in both 16x9 and 4x4
shapes can be enabled, as well as a center cross. Reticules can be separately enabled on the SD-SDI
and composite outputs.
The image processing is full 10-bit using a 24-tap spatial filter. Down-conversions of HD to SD
signals are de-jittered to reduce chroma phase jitter of SD analog signals. The analog output is
encoded at 12-bits (video plus sync) to preserve the 10-bit 4:2:2 component encoded video signal.
