Finalize
This process allows DVD-R to be played on compatible equipment.
Frame and field
Frames are the still pictures that go together to make a moving
picture. A frame is made up of two fields.
Frame
≥A frame still is made up of two alternating fields, so the picture
may appear blurred, but overall quality is high.
≥A field still is not blurred, but it has only half the information of a
frame still so picture quality is lower.
Linear PCM
This is a form of signal that has been digitized without compressing
it. CDs are recorded with 44.1 kHz/16 bit PCM, while DVDs use
PCM between 48 kHz/16 bit and 96 kHz/24 bit, allowing
reproduction of greater quality sound.
The linear PCM signals output from the DIGITAL AUDIO OUT,
OPTICAL terminal are stereo (2 channel).
NICAM
(NICAM Broadcasting System)
This is a 2 channel sound broadcast system which in most
instances provides high quality stereo sound. Broadcasters can
also transmit two separate mono soundtracks on this system.
Pan&Scan/Letterbox
In general, DVD-Video are produced with the intention that they be
viewed on a widescreen television with an aspect ratio of 16:9.
This means you can view most material with the intended aspect
ratio on a widescreen television.
Material with this ratio will not fit onto a standard television with an
aspect ratio of 4:3. 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)
This is a method of playing video CDs. You can select parts to play
by using menus recorded on the disc.
Play list
This is a collection of scenes. It enables you to play these scenes
in succession or to select specific ones to play.
Programme (PRG)
The section between the point where recording is started and the
point where it is stopped.
Field Field
Sampling frequency
This is the number of samples of sound taken per second during
conversion to a digital signal. A high sampling frequency results in
a sound close to the original when played back.
S-video output
The colour and luminance signals are separated before being sent
to the television, making for greater picture clarity.
Q Link Function (For the United Kingdom)
When the unit is connected via fully wired 21-pin Scart lead to the
TV, Q Link allows.
Download from the TVCopies the tuning set-up from your TV to
your unit.
Direct TV recording:
Immediately records the same programme that you are watching
on the TV.
TV/DVD Auto switch On:
whilst in standby mode pressing [1, PLAY], [SV/V+] or [PROG/
CHECK] will turn the TV and unit on.
Auto Switch Off:
When the TV is turned off, the unit will be turned off as well. This
function works in the stop mode.
PDC (For the United Kingdom)
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.
Title/Chapter (DVD-Video)
DVD-Video are divided up into large sections, titles, and smaller
sections, chapters. The numbers allocated to these sections are
called title numbers and chapter numbers.
Example
(1)
(3)
(1) Title 1
(2) Title 2
(3) Chapter 1
(4) Chapter 2
(5) Chapter 3
Track
This is the smallest division on CD, and Video CD, and usually
equates to a single song.
Example
