Glossary
HD (High Definition) - Used to describe video
content that is in one of the high definition
video formats. These are broadly 720i/p and
1080i/p. The 720 or 1080 refers to the number of
horizontal lines used to define the picture and
the “i” and “p” refer to “interlaced” or “progressive
scan”. Ordinary, “SD / Standard Definition” TV
used 576 lines (PAL standard).
Full-HD - HD television standard for 1080p
quality video, with 1080 horizontal lines.
HD Ready - HD television standard for 720p
quality video, with 720 horizontal lines.
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.
H.264: is a next-generation video compression
format. H.264 is also known as MPEG-4 AVC.
Developed for use in high definition systems
such as HDTV, Blu-ray as well as low resolution
portable devices, H.264 offers better quality at
lower file sizes than both MPEG-2 and MPEG-4
ASP (DivX or XviD). H.264 is sometimes referred
(erroneously) as x264 – x264 is the name of a
popular freeware encoder for the H.264 format.
H.264 is also sometimes referred to as MP4,
again this is technically incorrect. MP4 is a
container format much like AVI or MKV and it
can be used to “house” many different types of
compression codecs, not just H.264.
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.
