On Screen Setup

Sets the decode mode Status Bar to display on screen when
mode changes are made.
7.2.4 Status Bar Delay
Sets the length of time, from one to ten seconds, that the
Status Bar remains visible following a control command.
7.2.5 Screen Saver
Sets a Screen Saver to operate after five minutes of display
inactivity. Select from on and off .
Note: Only disable the Screen Saver if the display is not sensitive
to “burn-in”.
7.3 Video Setup
Selection of Video Setup from the top level menu generates a
second level menu described and illustrated below.
7.3.1 Video System and Output Format
Selects between NTSC, PAL and auto (disc dependent) video
output. This menu overrides the Front Panel video set up
described in Section 8.1
Note: If the display is working satisfactorily this setup stage may
not be required.
The selection of NTSC , PAL or auto depends on the capability
of the display device connected. Many displays are limited
either to PAL or NTSC and if this is the case for your display
the appropriate option should be selected. The n-Vi will convert
PAL encoded programme material to NTSC if NTSC is selected,
or convert NTSC to PAL if PAL is selected - display quality may
however suffer.
If the display supports both NTSC and PAL the auto option
should be used. Auto switches the DVD output to NTSC or PAL
depending on the disc format. The combination of a multi-
standard display and the
auto option ensures the highest video
quality as no format conversion need take place.
Note: If Auto is selected the On Screen Display will show “Auto”
folllowed by the currently selected format.
Note: A black and white picture is often a sign that a PAL only
display is being fed an NTSC signal.
7.3.2 Black Level
Black Level adjustment is effective when NTSC output is
selected. Black Level defines the brightness level at which
image information will be displayed as black. A video brightness
signal is measured in IRE units on a scale from 0 (black) to
100 (white). In American NTSC encoding the value of 7.5 IRE is
the “black level cutoff”.
Note: Black level adjustment only affects NTSC material.
7.3.3 SCART Settings
The player’s SCART output connector carries video signals
in both composite and component forms with two alternate
varieties of the component format - RGB or YPbPr - available.
If using component video from the SCART connector, select the
variety appropriate to the display connected.
Note: Composite and component video and the various signal
formats are explained in Section 10.
7.3.4 Test Patterns
Provides three display Test Patterns intended to help calibrate
the player and display combination and ensure optimum
performance. The Test Patterns are primarily intended for
advanced users or video service engineers. Make a note of all
display and n-Vi settings prior to making any adjustments, and
ensure the display user manual is available for reference.
Note: It is not always necessary to make calibration adjustments
based on the test patterns. The n-Vi and display default settings
will in the majority of cases provide excellent results.
Note: Help text for each test pattern is available by pressing the
handset menu key.
Note: The player must be in stop mode to display the test
patterns.
Overscan Test Pattern
Adjust the display’s
horizontal, vertical, aspect
ratio and zoom controls until
the test pattern is central
and spills over the edge of
the display by approximately 5%. On a wide-screen display the
circle labelled 16:9 should appear undistorted.
Grey Scale Test Pattern
Adjust the display’s
brightness until the 0%
box looks black. Adjust the
display’s contrast until the
100% box is a clear bright,
undistorted white. Ensure no two of 5% boxes appear the same.
