Disc-related terms

DVD +R / DVD +RW
DVD +R is two different standards for recordable DVD
drives and discs. This format allows information to be
recorded onto the DVD disc only once.
DVD +RW is two standards for re-writable media,
meaning the DVD content can be erased and re-
recorded. Single-sided discs can hold 4.38 Gigabytes
and double-sided discs hold twice as much.
VCD (Video CD)
A VCD holds up to 74 minutes (650 MB disc) or 80
minutes (700 MB disc) of MPEG-1 full-motion video
along with quality stereo sound.
MPEG
MPEG is an international standard for video and audio
compression. MPEG-1 is used in encoding video for
VCD and provides for multichannel surround sound
coding such as PCM, Dolby Digital, DTS and MPEG
audio.
MP3
MP3 is a popular compression format used for digital
audio files that yields very high near-CD quality.
JPEG
Joint Pictures Expert Group. JPEG is a compressed
file format that allows you to save images with no limit
on the number of colors.
PBC: Playback Control (Video CD only)
Playback control is available for Video CD (VCD)
version 2.0 disc formats. PBC allows you to interact
with the system via menus, search functions, or other
typical computer-like operations. Moreover, still
pictures of high resolution can be played if they are
included in the disc. Video CDs not equipped with
PBC (Version 1.1) operate in the same way as audio
CDs.
Title (DVD video discs only)
A title is generally a distinct section of a DVD disc. For
example the main feature could be title 1, a
documentary describing how the film was made could
be title 2, and cast interviews could be title 3. Each
title is assigned a reference number enabling you to
locate it easily.
6
Chapter (DVD video discs only)
A chapter is a segment of a title such as a scene in a
film or one interview in a series. Each chapter is
assigned a chapter number, enabling you to locate the
chapter you want. Depending on the disc, chapters
may not be recorded.
Scene (VCD)
On a video CD with PBC (playback control) functions,
moving pictures and still pictures are divided into
sections called "scenes". Each scene is displayed in
the menu screen and assigned a scene number,
enabling you to locate the scene you want. A scene is
composed of one or several tracks.
Track
A distinct element of audiovisual information, such as
the picture or sound track for a specific language
(DVD), or a musical piece on a video or audio CD.
Each track is assigned a track number, enabling you
to locate the track you want. DVD discs allow one
track of video (with multiple angles) and several tracks
of audio.
Regional code of the recorder and DVDs
This recorder is designed and manufactured
2
for playback of Region 2 encoded DVD
software. The region code on the labels of
some DVD discs indicates which type of the recorder
can play those discs. This unit can play only DVD
discs labeled 2 or ALL. If you try to play any other
discs, the message "Incorrect region code. Can't play
back" will appear on the TV screen. Some DVD discs
may not have a region code label even though their
playback is prohibited by area limits.
Notes on DVDs and Video CDs
Some playback operations of DVDs and Video CDs
may be intentionally fixed by software manufacturers.
As this unit plays DVDs and Video CDs according to
disc content designed by the software manufacturer,
some playback features of the unit may not be
available or other functions may be added.
Refer also to the instructions supplied with the DVDs
and Video CDs. Some DVDs made for business
purposes may not be played on the unit.
