Glossary
Pan&Scan/Letterbox
In general, DVD-Video are produced with the intention that they be
viewed on a widescreen television (16:9 aspect ratio), so images
often don’t fit regular (4:3 aspect ratio) televisions. Two styles of
picture, “Pan & Scan” and “Letterbox”, deal with this problem.
Pan & Scan: The sides are cut off so the picture
fills the screen.
Letterbox: Black bands appear at the top and
bottom of the picture so the picture
itself appears in an aspect ratio of
16:9.
Playback control (PBC)
If a Video CD has playback control, you can select scenes and
information with menus.
(This unit is compatible with version 2.0 and 1.1.)
Progressive/Interlace
The PAL video signal standard has 625 (or 576) interlaced (I) scan
lines, whereas progressive scanning, called 625P (or 576P), uses
twice the number of scan lines. For the NTSC standard, these are
called 525I (or 480I) and 525P (or 480P) respectively.
Using progressive output, you can enjoy the high-resolution video
recorded on media such as DVD-Video.
Your television must be compatible to enjoy progressive video.
Panasonic televisions with 625 (576)/50I · 50P, 525 (480)/60I · 60P
input terminals are progressive compatible.
Protection
You can prevent accidental erasure by setting writing protection or
erasure protection.
Sampling frequency
Sampling is the process of converting the heights of sound wave
(analog signal) samples taken at set periods into digits (digital
encoding). Sampling frequency is the number of samples taken per
second, so larger numbers mean more faithful reproduction of the
original sound.
VBR (Variable bitrate)
This is a method of video recording that adjusts the bit rate
according to video signal.
Q Link
This function works only if the unit is connected via a fully wired 21-
pin Scart lead to a TV featuring the Q Link or similar function.
Q Link offers the following functions:
≥
Download from the TV
§
When you connect the unit to a TV, the station list data is
automatically copied from the TV to the unit, and the TV stations
are assigned to the programme positions on the unit in the same
order as on the TV.
≥

By simply pressing [
¥
DIRECT TV REC], you can at once record
the same programme that you are watching on the TV.

PDC (Programme Delivery Control)
Programme Delivery Control adjusts the start and stop time of a timer recording automatically to ensure the recording starts and finishes in line
with the programme broadcast. This is useful when a programme over-runs the published times.
The station must be transmitting PDC and the exact time must be set for PDC to work.
The unit detects whether a station is transmitting PDC only during the tuning process.
If PDC is introduced or discontinued by a station you will need to re-tune the unit before it becomes aware of this.
PDC transmissions are not currently nation-wide so please check with your local broadcaster for more information.
The beginnings of recordings may not be recorded correctly in some cases.
