PSM192-Progressive Scan Module
This parameter assists the PSM192 in
deciding whether the incoming video signal
has been recorded using a video or a film
camera - essential to achieve highest vertical
picture resolution.
Video
will be most
appropriate for most television broadcasts,
whilst
High Film Bias
is best for most DVDs.
High Video Bias
, assumes a mixture of
recordings on video and film - it can lead to
flicker if the source material includes
predominately video based material.
1. the horiziontal resolution is increased from 720 to 960
The PSM192 can reformat recordings in 4:3 aspect ratio for display on a 16:9 screen by
adding black bars either side
(1)
. However, the PSM192 cannot detect the aspect ratio of an
incoming video signal except that coming from our DVD player DVD32. The advantage of
the feature is that the video output becomes always 16:9, requiring no scaling within the
display device.

The ideal black level setting is when you can still see image details in dark areas, whilst
black areas are true black. For best results use a PLUGE test pattern or a test pattern showing
different shades of grey.
The ideal white level setting is when white areas are true white without blurring at their
edges, whilst still allowing different grades of grey to be seen. For best results, use a suitable
test pattern, e.g. a needle pulse or different shades of grey.
The ideal colour setting displays colours without over-saturating them. Check the colour of
skin displayed, or better still use a suitable test pattern and colour filters.
This control applies only to NTSC sources: the value is set correctly when there is no green or
yellow cast in the picture. For best results use a suitable test pattern and colour filters. It is not
necessary to set this parameter when the DVD32 picture is selected.
