Composite (CVBS) - Low quality analogue video
signal format. Can carry PAL signal..
Component (YPbPr) - Higher quality analogue
video signal format. Splits the video signal into
three components to maintain signal clarity and
capable of carrying high definition video up to
1080p. Component is rapidly being phased out in
favour of digital video via HDMI.
HDMI: High Definition Multimedia Interface. A
specification developed by the HDMI Working
Group that combines multi-channel audio and
high definition video and that controls signals into
a single digital interface for use with DVD players,
digital television, and other audiovisual devices.
Aspect ratio: The ratio of vertical and horizontal
sizes of a displayed image. The horizontal vs.
vertical ratio of conventional TVs is 4:3, and that of
widescreens is 16:9.
Disc menu: A screen display prepared for allowing
selection of images, sounds, subtitles, multi-angles,
etc recorded on a DVD.
JPEG: A very common digital still picture format. A
still-picture data compression system proposed
by the Joint Photographic Expert Group, which
features small decrease in image quality in spite of
its high compression ratio.
XviD: MPEG-4 based video compression technology,
that can shrink digital video to sizes small enough
to be transported over the internet, while
maintaining high visual quality.
Container. The multimedia container file is used
to identify and interleave different data types.
Simpler container formats can contain different
types of audio codecs, while more advanced
container formats can support multiple audio and
video streams, subtitles, chapter-information, and
meta-data (tags) — along with the synchronization
information needed to play back the various
streams together. There are many container
formats, such as AVI, Matroska (MKV), MOV, MP4,
OGM, WAV, etc.
Analog: Sound that has not been turned into
numbers. Analog sound varies, while digital sound
has specific numerical values. These jacks send
audio through two channels, the left and right.
Digital: Sound that has been converted into
numerical values. Digital sound is available when
you use the DIGITAL AUDIO OUT COAXIAL or
OPTICAL jacks. These jacks send audio through
multiple channels, instead of just two channels as
analog does.
PCM (Pulse Code Modulation): A system for
converting analog sound signal to digital signal for
later processing, with no data compression used in
conversion.
S/PDIF - Format for carrying audio digitally over
either optical (TOSLINK) or electrical (Coaxial) cable.
Can carry high quality DTS or Dolby Digital audio.
TOSLINK - Standardised optical fibre connection
system invented by Toshiba. Typically used to
connect the Player to a AV receiver for pass-through
of HiFi audio. When we refer to digital optical we
mean S/PDIF via TOSLINK.
Dolby Digital (or AC-3) - It isa surround sound
system developed by Dolby Laboratories
containing up to six channels of digital audio (front
left and right, surround left and right, center and
subwoofer). It is a required standard of both Blu-
Ray and DVD and the most widely supported. It
is a ‘lossy’ format so is of a lesser quality than the
studio original. Surround sound up to 5.1 channel is
supported. The Dolby Digital audio track can either
be decoded (downmixed) to stereo in the Player
or digitally bitstreamed direct (passthrough) to a
compatible AV receiver (via TOSLINK/Coaxial/HDMI)
for decoding.
DTS (Digital Theater System) - is a required
standard of both Blu-Ray and DVD players and is
widely regarded to produce audio quality superior
to Dolby Digital. Up to 5.1 channel surround sound
is supported. DTS is a ‘lossy’ compression standard
so the audio is of a lesser quality than the original
studio recording. The DTS audio track can either
be decoded (downmixed) in the Player to stereo
or digitally bitstreamed direct (passthrough) to a
compatible receiver (via TOSLINK/Coaxial/HDMI) for
decoding.
Bit Rate: The amount of data used to hold a given
length of music; measured in kilobits per seconds,
or kbps. Or, the speed at which you record.
Generally, the higher the bit rate, or the higher
the recording speed, the better the sound quality.
However, higher bit rates use more space on a Disc.
Title: The longest section of a picture or music
feature on DVD, music, etc., in video software, or
the entire album in audio software. Each title is
assigned a title number enabling you to locate the
title you want.
Chapter: Sections of a picture or a music piece on a
DVD that are smaller than titles. A title is composed
of several chapters. Each chapter is assigned a
chapter number enabling you to locate the chapter
you want.
Parental Control: A function of the DVD to limit
playback of the disc by the age of the users
according to the limitation level in each country.
The limitation varies from disc to disc; when it
is activated, playback will be prohibited if the
software’s level is higher than the user-set level.
Surround: A system for creating realistic
threedimensional sound fields full of realism by
arranging multiple speakers around the listener.
