Glossary
Aspect Ratio
The height-to-width ratio of a television set’s screen. Con-
ventional televisions had aspect ratios of 4:3 but widescreen
television sets have a 16:9 ratio, for richer viewing enjoyment.
Interlaced
Each frame of displayed playback is divided into two fields:
the first field paints the odd-numbered scanning lines, and
the persistence of vision of the eye is used to allow the next
field of even-numbered scanning lines to be painted, thus
completing a single complete frame. This method is used as
the standard scanning system in conventional television re-
ceivers. In this unit’s Operating Instructions, interlaced reso-
lutions are indicated by the “i” following the resolution number
(e.g., 525i).
Video output (composite)
A video signal transmitted in the form of a single code com-
posed of luminance signal (Y) and color signal (C). However,
the device receiving the signal must separate the luminance
(Y) and color (C) components once again. The image quality
is determined by the accuracy with which these two compo-
nents can be divided.
Component output signal
The entire component output signal is composed of the three
elements luminance Y, C
B
/P
B
, and C
R
/P
R
, with the result that
connecting to a television monitor equipped with component
inputs will results in the production of a more beautiful im-
age.
Parental Lock
Some commercial DVDs with violent or mature contents are
provided with parental viewer control levels (higher and lower).
By setting the player’s Parental Lock level to a value lower
than the level of the disc, playback of these discs can be
prevented unless an individually set password is input.
Optical digital output
Audio channels are normally converted to electrical signals
and sent from the player to an amplifier or other device; with
optical digital output, however, the signals are converted to
light signals and transmitted via an optical fiber (the receiving
amplifiers and other devices are equipped with optical digital
inputs).
Video Recording format (VR mode)
A recording mode in which video images and audio signals
are written in real time * straight to to non-specific locations
on a DVD-RW disc. (*On a computer, input data is quickly
written to a hard disk (or removable media), but it is first stored
in the memory. Thereafter, the CPU (OS) establishes the or-
der of the data and writes the data to the hard disk. In con-
trast, when data is written to the hard disk in the immediate
order in which is received, it is called “real-time” recording).
Pioneer’s DVD recorders calls this “VR mode recording.” VR
mode includes the normal video quality recording mode, and
other modes in which image quality and recording time can
be set freely.
Playback Control (PBC)
Signals recorded on Video CDs (Version 2.0) and used to con-
trol playback. Using the menu screens recorded on Video-
CDs with PBC allows simple conversational control of disc
and search functions for more enjoyable playback. High- and
Low-resolution still images can also be enjoyed.
Progressive Scan
Each video frame is not divided into two, but instead scanned
as a single whole frame. This scanning mode produces beau-
tiful, no-flicker playback particularly when displaying written
text on still images, or pictures with numerous graphics and
horizontal lines. In this player’s Operating Instructions, pro-
gressive scan resolutions are followed by a “p” designator
(e.g., 525p).
Multi-angle
Some commercial DVD software is recorded with images
taken simultaneously from multiple camera angles. With DVD
video, up to 9 angles can be recorded.
DVD Video format recording
A recording format in which data is written continuously to
the DVD-R/DVD-RW disc using the same format used with
commercial DVD software disc bearing the
or
logos.
Pioneer DVD recorders refer to this as Video Mode record-
ing. Video mode includes alternatives for both high-image-
quality recording and long-time recording.
DVI
Digital Visual Interface. A standard for transmitting video sig-
nals to a digitally-driven display monitor. Since analog signal
conversion is not required, high image quality is preserved.
GUI
Graphical User Interface. An environment in which menus
are displayed on screen and provide for easy operation.
HDCP
High Definition Copy Protocol. A copy-protection scheme
designed to protect copyrighted contents.
HDMI
High Definition Multimedia Interface.
A digital interface standard for next-generation television that
expands on the DVI (Digital Video Interface) standard.
OSD
Abbreviation for On-Screen Display. A function that displays
current operating conditions on the screen.
S-Video Output
A type of video signal in which the luminance (Y) and color (C)
components are transmitted separately. Since no conversion
is needed to separate the luminance and color components,
it provides a higher quality image than those produced with
composite signals.
