Noise Reduction

This  screen  allows  various  forms  of  noise
reduction to be applied to the signal.

Noise Reduction

Noise Reduction Enable

When  enabled  the  noise  reduction  system  will  be
active. Default is to Off.

Y Noise Reduction

This  item  allows  Recursive  noise  reduction  to  be
applied to the luminance channel.

The  range  of  adjustment  is  off,  low,  medium  and
high. Default is to Medium.

C Noise Reduction

This  item  allows  Recursive  noise  reduction  to  be
applied to the chrominance channel.

The  range  of  adjustment  is  off,  low,  medium  and
high. Default is to Medium.

Recursive Threshold

This  control  sets  the  noise  reduction  threshold  of
the recursive filters.

The range of adjustment is from Auto (0) to 7 units.
Preset is to Auto (0).

Note  that  applying  a  high  threshold  level  may
assist  with  extremely  noisy  images;  however  this
may result in plain areas appearing flat.

Filters

Sparkle

Enabling  this  item  applies  a  sparkle  filter  to  the
signal,  reducing  the  effect  of  sparkle  noise
associated  with  edge-of-reception  signals  from
satellite  feeds,  impulse  noise  or  drop-outs  from
tape-recorded signals.

Median

When  selected  sparkle  concealment  is  enabled
that  employs  a  threshold  controlled  3-dimensional
median  filter.  This  permits  the  removal  of  picture
disturbances  that  the  normal  sparkle  detection
algorithm  may  miss.  For  example  low-level
sparkles  will  be  concealed.  The  Median  filter  is
particularly  effective  on  very  noisy  sources.  Note
that  some  loss  of  resolution  may  be  observed
depending on the source material.

Split Screen

This  function  allows  the  effects  of  noise  reduction
to be easily seen by splitting the screen in half.
One half will show the picture with noise reduction
and the other half without noise reduction.

Off 

This disables the split screen function.

Left-Right

When  enabled,  the  screen  will  be  split  into  two
equal sections separated by a vertical white line.
The  processed  picture  will  occupy  the  left  hand
section of the screen and the unprocessed picture
will occupy the right hand side section.

Top-Bottom

When  enabled,  the  screen  will  be  split  into  two
equal sections separated by a horizontal white line.
The  processed  picture  will  occupy  the  bottom
section of the screen and the unprocessed picture
will occupy the top section.
