7.6.2 Motion Compensation
Motion Compensation
is a function of progressive scan video
processing that overcomes the visible artifacts that can result
when interlaced video data (see Section 14) is de-interlaced
for conversion to progressive scan. If a video scene contains
elements in motion, the two fields of an interlaced image cannot
simply be combined for progressive scan as the time delay
between the fields will result in visible distortion of the moving
image - it will appear jagged. Motion Compensation overcomes
the distortion by dynamically interpolating between differences in
the fields of data. If there is no movement in a scene however,
the interpolation may result in a loss of image sharpness.
The
Motion Compensation
menu provides three options
-
none
,
adaptive
and
full
. Selecting
none
disables Motion
Compensation, selecting
adaptive
applies Motion Compensation
dynamically depending on the intensity of movement in the
scene, and selecting
full
applies Motion Compensation to
all programme material.
Adaptive
should be selected for the
majority of programme material.
Full
or
none
may be appropriate
to material featuring intense motion, or still images respectively.
7.6.3 Film Mode
Film Mode
enables the player to optimise the display of
programme material that has been converted from film to video
(DVD) format. Film Mode should be selected for programme
material that is known to be derived from a cine-film original.
Leaving Film Mode selected for original video material may still
result in satisfactory display, however, it should be de-selected
for this type of material if motion or sync problems occur.
7.6.4 30 fps (frames per second) Detection
30 FPS Detection
supports
Film Mode
in identifying specific
NTSC/PAL film to video conversion issues. Generally, detection
should be selected for NTSC cine-film derived and all PAL
format material, and de-selected for NTSC format video derived
material. The default setting is
on
.
7.6.5 Edit Compensation
The techniques employed by
Film Mode
and
30 FPS Detection
can sometimes be disturbed by poorly resolved edits in
programme material.
Edit Compensation
identifies edits
likely to cause problems and trades ultimate picture quality
against motion or sync errors.
Low
should be selected for
most programme material unless motion or sync errors are
unacceptable. Increasing Edit Compensation will result in
smoother display but reduced picture quality.
7.6.6 Picture Adjustment
Three separate
Picture Adjustment
sub-menus are available.
One that provides adjustment of the player’s
High Definition
RGB
output, one that provides adjustment of the player’s
High
Definition
YPbPr (YUV)
output and one that is common to both.
Each signal channel of the
RGB
outputs can be independently
adjusted. For example, to emphasise red, green or blue tones in
an
RGB
picture boost the R, G or B channels respectively.
YPbPr
adjustment covers luminance and saturation only.
The picture adjustments common to
High Definition
outputs are
Vertical Offset
,
Horizontal Offset
and
YC Delay
.
The
Offset
adjustments enable the picture to be properly centred
in the display screen.
YC Delay
adjustment provides compensation for the timing errors
that can occur between the colour and brightness elements of
a video signal. Errors are most likely to be visible if the player is
required to carry out intensive processing to generate a display
signal. YC Delay is best left at its default adjustment unless
picture abnormalities that cannot be corrected by any other
means are apparent.
Note:
Offset and YC Delay adjustment made from this menu will
also be reflected in the player’s DVI output.
Note:
No picture adjustment is available on the player’s SCART and
S-Video outputs.
7.7 Audio/AV2 Setup
Selection of
Audio Setup
from the top level menu generates
a second level menu comprising the options listed below. The
availability of options in the second level menu depends on
either the installation of a
Multi-channel Card (McC)
or DVD5
connection to an
AV2 Processor.
Note:
When a DVD5 is connected to an AV2, adjustment of Audio
Setup parameters actually adjusts AV2 functions. The AV2 front
panel or handset setup interface is disabled while the DVD5 on
screen setup menus are displayed. If the AV2 front panel or handset
interface is subsequently used to adjust any Audio Setup parameters
the DVD5 menu will update automatically.
Note:
Th AV2 must be running software version 01-04 or later.
Note:
Use a CAT5 interface cable to connect a DVD5 to an AV2.
See diagram 11.2.
7.7.1 Digital Audio Output
Selects the player’s
Digital Audio Output
format from
Multi-
channel
(i.e Dolby Digital, DTS, etc) or
Stereo
(PCM stereo)
options. Multi-channel output will be either the previously
selected audio track, the player preference or the specific
disc default. PCM stereo output is a down-mix of the currently
selected audio track.
Note:
The player must be in stop mode to select audio outputs.
7.7.2 Sub-woofer Cut-off Frequency
Note:
Function only available with AV2 connected.
Sub-woofer Cut-off Frequency
provides adjustment of the
cut-off frequency between the sub-woofer and any small
loudspeakers. It should be adjusted to suit the sub-woofer and
speakers in use. Their specifications should provide guidance.
7.7.3 Bass Mix
Note:
Function only available with McC installed or AV2 connected.
Selection of
Bass Mix
routes the front left and right speaker low
frequency signals additionally to the sub-woofer channel.
