Changing the Color System

This system is compatible with the PAL and NTSC systems. Select
the color system to match the color system of your TV.
• PAL is the initial setting.
• You can change the color system only when the unit is on
standby.
From the remote control ONLY:
Press NTSC/PAL.
• Each time you press the button, the TV system
alternates between "NTSC" and "PAL."
NTSC: Select this when the color system of your TV is
NTSC.
PAL: Select this when the color system of your TV is
PAL.

Changing the Scanning Mode

ONLY for NTSC TVs:
This system supports the progressive scanning system (525p*) as
well as the conventional interlaced scanning system (525i*).
If your TV equipped with component video jacks supports the
progressive video input, you can enjoy a high quality picture by
activating the progressive scanning mode.
• Refer also to the instruction manuals supplied with your TV.
• If your TV equipped with component video jacks does not support
the progressive video input, do not change the scanning mode to
the progressive scanning mode.
* 525p and 525i indicate the number of scanning lines and scanning
format of a video signal.
• 525p indicates 525 scanning lines with progressive format.
• 525i indicates 525 scanning lines with interlaced format.
You can select the scanning mode if your TV equipped with
component video jacks supports the progressive video input.

Notes:
• Some progressive TVs and High-Definition TVs are not fully
compatible with this system, resulting in the unnatural picture when
playing back a DVD in the progressive scanning mode.
In such a case, change the scanning mode to "INTERLACE TV."
To check the compatibility of your TV, contact your local JVC
customer service center.
• All JVC progressive TVs and High-Definition TVs are fully
compatible with this system.
About scanning system
The conventional scanning method to display video signals on
the TV screen is called "Interlaced scanning." With this method,
only half of the horizontal lines (called a "field") are displayed
at a time. So two fields complete a single picture (frame); i.e.,
the first field, containing all the odd-numbered lines, is
followed by the second field, containing all the even-numbered
lines.
On the other hand, the Progressive scanning system scans all
horizontal lines at a time, so you can double the number of
scanning lines displayed at a time, resulting in a flicker-free,
high-density picture.
To enjoy the progressive scanned picture, a monitor (or TV or
projector) connected to the system must support the progressive
video inputs.
Depending on the material source format, DVD video can be
classified into two types; film source and video source (note
that some DVD video contain both film source and video
source). Film sources are recorded as 24-frame-per-second data,
while (NTSC) video sources are recorded as 30-frame-per-
second (60-field-per-second interlaced).
When this system plays back a film source data, uninterlaced
progressive output signals are created using the original data.
When a video source is played back, the unit interleaves lines
between the interlaced lines to create the pseudo uninterlaced
picture and outputs as the progressive signals.
