NOTE:

For the items marked “*,” you can assign a different setting for each source including FM and AM.

Changing the scanning mode

This system supports the progressive scanning system (525p*) as wel as the conventional interlaced scanning system (525i*).

If your TV equipped with component jacks supports the progressive video input, you can enjoy a high quality picture by making the progressive scanning mode active.

Refer also to the instruction manuals supplied with your TV.

If your TV equipped with component jacks does not support the progressive video input, do not change the scanning mode to the progressive scanning mode.

Press and hold PROGRESSIVE for 5 seconds.

Each time you press and hold the button, the scanning mode alternates between “PROGRESSIVE” and “INTERLACE.”

INTERLACE :Select only when your TV equipped with component jacks supports the interlaced video input.

PROGRESSIVE :Select when your TV equipped with component jacks supports the progressive video input.

The PROGRESSIVE lamp on the center unit lights up when you select “PROGRESSIVE” as the scanning mode.

NOTES:

When “PAL” is selected on the VIDEO OUT SELECT switch (see page 7), the scanning mode is fixed to “INTERLACE.” So the scanning mode cannot be changed.

There are some progressive TVs and High-Definition TVs that 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.” 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.

*525p and 525i indicate the number of scanning lines and scanning format of an image signal.

525p indicates 525 scanning lines with progressive format.

525i indicates 525 scanning lines with interlaced format.

About scanning system

To display video on the TV screen, the conventional scanning method is called “Interlaced scanning.” With this method, only half of the horizontal lines 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 displayed 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 video, a monitor (or TV or projector) to be connected to the unit must have the Progressive 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 information, while (NTSC) video sources are recorded as 30-frame-per-second (60-field-per-second interlaced) information.

When this system plays back a film source material, uninterlaced progressive output signals are created using the original information. When a video source material is played back, the unit interleaves lines between the interlaced lines on each to create the pseudo uninterlaced picture and outputs as the progressive signal.
