Changing the Scanning Mode

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 (P–SCAN 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.
From the remote control ONLY:
1
Press DVD.
You can change the scanning mode only when DVD is
selected as the source and playback stops.
If a disc is no loaded, go to step 3 .
2
Press 7.
Playback stops.
3
Press and hold PROGRESSIVE for a
while.
• Each time you press and hold the button, the
scanning mode alternates between "I–SCAN MODE"
and "P–SCAN MODE".
I (Interlace)–SCAN MODE
: Select this if your TV equipped with component video jacks does
not support the progressive video input (conventional TV).
P (Progressive)–SCAN MODE
: Select this if your TV equipped with component video jacks
supports the progressive video input.

Notes
• Progressive scanning mode is available only when color system of
NTSC is selected.
• 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 "I–SCAN MODE."
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.
To select an appropriate progressive mode for playback pictures, see
"Selecting an Appropriate Progressive Mode" on page 16.
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
DVD
between the interlaced lines to create the pseudo uninterlaced
picture and outputs as the progressive signals.
