7.5 Video Setup
Selection of
Video Setup
from the top level menu generates a
second level menu comprising the options listed below.
7.5.1 Output Format
Selects between
NTSC
,
PAL
and
auto
(disc dependent) video
output. This menu overrides the initial video set up option
selected in Section 7.1.1.
The selection of
NTSC
,
PAL
or
auto
depends on the capability of
the display device connected and the choice between Interlaced
and Progressive Scan video. Many displays are limited either to
PAL or NTSC for Interlaced video and if this is the case for your
display the appropriate option should be selected. Similarly,
many displays do not support PAL for Progressive Scan video so
selection of the NTSC option may well be necessary when using
Progressive Scan - even if PAL is used for Interlaced video. The
DVD5 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 your 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.
7.5.2 Black Level
Black level
adjustment is available 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.
7.5.3 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 14 of this manual.
7.5.4 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 DVD5 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 DVD5 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.
75% Colour Scale Test Pattern
The display must be viewed using a 47b blue separation filter.
Adjust the display’s colour and tint/hue control until the four
large boxes (1, 2, 3 and 4) appear the same shade of blue.
7.5.5 Lip Sync (Audio/Video delay)
DVD video and audio can sometimes appear to be a little out of
synchronisation.
Lip Sync
provides adjustment in 10mS steps
to compensate for any apparent error. Use the handset
left (
3
)
key to delay the audio and
right (
4
)
key to delay the video.
7.5.6 Display Aspect Ratio
Sets the player to output video appropriate to the display. For
16:9 (widescreen) displays, non-widescreen programme material
will be accommodated by leaving a proportion of the display
either side of the picture unused. Widescreen material on 4:3
(conventional) displays can be accommodated by selecting either
the
pan-scan
or
letter box
options. The
pan-scan
option uses
the full height of the display but dynamically pans the material
to ensure that the important information is always displayed. The
letter box
option displays the material’s full width but leaves a
proportion of the display above and below the picture unused.
7.5.7 Video Outputs Off
Enables unused video sockets to be selectively switched off
during playback. Switching off the video sockets will improve
sound quality of audio CD and DVD-A material.
Note:
All video outputs will operate when player is in stop mode or
when the OSD menu is displayed.
7.6 High Definition Video Setup
Selection of
High Definition Video Setup
from the top level
menu generates a second level menu comprising the options
listed below.
The
High Definition Output
menus enable selection of the signal
format to be output from the player’s
BNC
sockets.
Generally, the signals available from the BNC sockets provide
improved quality over the SCART and S-Video outputs through
improved digital to analogue conversion and extra image
adjustment functions.
7.6.1 Colour Format
The
Colour Format
sub-menu enables selection of the video
signal
Colour Format
(RGB, YPbPr, etc). The options available
will depend on the selection made in the previous menu.
Note:
The various video colour formats are explained in Section 14
of this manual.
