Doubler and Quadrupler
Selection
At the discretion of the user, the choice of the
number of lines displayed is selectable using the
remote or front panel controls. Personal
preferences dictates the choice between: |
Line doubler Mode:
525 Line progressive Scan / 1050 Lines per NYSC
Input Frame
Line Quadrupler Mode: 1050 Line
Progressive Scan / 2100 Lines per NTSC Input

In both the Line Doubler and Line Quadrupler
signal paths. |
Digital Precise Adaptive
Two Dimensional Comb Filter
Picture information from the luminance and chroma
pixels left, right, above and below the current
pixel are analyzed to minimize cross luminance
(hanging chroma dots) and cross chroma (rainbow
effects) while maintaining maximum picture
resolution. |
Digitally Precise Two
Dimensional Spatial Detail Spectrum Expansion to
Maximize Apparent Picture Resolution
The SC-4200 uses information from three discreet
video input lines, the present line, the previous
line and the future line to provide exceptional
detection of picture details in the presence of
noise. This selectively emphasizes small details
without over enhancing large object boundaries.
Thus, avoiding the harsh, "cartoon like edge
effects around faces that are common to less
sophisticated "sharpness controls". The
result is a picture which mimics subjectively the
appearance of a picture with one and one half
greater bandwidth and resolution. |
Chroma Resolution
Augmentation
In NTSC chroma resolution is transmitted in the
best case at only one third the luminance
resolution Commonly the chroma resolution is one
quarter or less the luminance resolution. The
worst case most customers might see is during VCR
playback where the chroma resolution may be only
one-twelfth of an NTSC broadcast luminance
resolution. the result in the picture is that the
red of a woman's lipstick starts significantly
before (to the left of) and ends after (to the
right of) the luminance portion of the lips. The
SC-4200 first analyses the chroma for changes in
level and hue to develop a correction signal to
reduce transition times. (Chroma Empowered by
Chroma) Then the relatively wideband luminance is
used to exploit the normal chroma luminance
coherence. A luminance derived "helper"
signal is utilized to strengthen the chroma
risetime in the proximity of the luminance
transition and further reduce the chroma
transition times, augmenting chroma resolution.
(Chroma Empowered by Luminance) |
Spatially Correct Three
Dimension Motion Detection
A three dimensional kernal of pixels is digitally
investigated to detect motion in the presence of
noise. This results in the smooth transformation
from assembling a pixel in the adjacent field
(intra-field or inter-frame compilation) or
creating a new pixel from information from the
surrounding pixels (inter-field interpolation). |
Automatic Film Mode
Selection
Automatically analyses and detects the sequence
of motion, comparing 24 frame per second film
verses 60 field per second video picture content
and produces a histogram which is then used to
select the optimum mode, film (2-3 pulldown,
progressive input) or video to minimize motion
artifacts. |
Multiple Input Sources
Component / RGB / S-Video / Composite |
User Custom Presetable
Operational Memories
Four non-volatile memories for each input allow
picture preferences to be stored. This totals
sixteen separate memories for brightness,
contrast, color, tint, and detail. |
Control Options
Infrared remote control / Front panel control /
RS-232 digital remote control |
