Glossary
AVCHD
AVCHD is a new format (standard) for high defi nition video cameras
that can be used to record and play high-resolution HD images.
Bitstream
This is the digital form of multi-channel audio data (e.g., 5.1 channel)
before it is decoded into its various channels.
Decoder
A decoder restores the coded audio signals on discs to normal. This
is called decoding.
Deep Colour
This unit incorporates HDMI
that can reproduce greater colour gradation (4096 steps) when
connected to a compat ble TV.
You can enjoy exceptionally rich, natural-looking colours, with smooth,
detailed gradation and minimal colour banding.
[A lower colour gradation (256 steps), without Deep Colour, will be
reproduced if connected to a TV which does not support Deep Colour. The
unit will automatically set appropriate output to suit the connected TV.]
DivX
DivX is a popular media technology created by DivX, Inc. DivX media
fi les contain highly compressed video with high visual quality that
maintains a relatively small fi le size.
DNS Server
A server which acts like a telephone directory and translates Internet
domain names into IP addresses.
Dolby Digital
This is a method of coding digital signals developed by Dolby
Laboratories. Apart from stereo (2-channel) audio, these signals can
also be multi-channel audio.
Down-mixing
This is the process of remixing the multi-channel audio found on
some discs into fewer channels.
Drive
In the instance of this unit, this refers to the hard disk (HDD), disc (DVD)
and SD card (SD). These perform the reading and writing of data.
DTS (Digital Theater Systems)
This surround system is used in many movie theaters. There is good
separation between the channels, so realistic sound effects are
possible.
Dynamic range
Dynamic range is the difference between the lowest level of sound
that can be heard above the noise of the equipment and the highest
level of sound before distortion occurs.
Dynamic range compression means reducing the gap between the
loudest and softest sounds. This means you can listen at low
volumes but still hear dialogue clearly.

Film and video
DVD-Videos are recorded using either fi lm or video. This unit can
determine which type has been used, then uses the most suitable
method of progressive output.
Film:
Recorded at 25 frames per second (PAL discs) or 24
frames per second (NTSC discs). (NTSC discs
recorded at 30 frames per second as well.) Generally
appropriate for motion picture fi lms.
Video:
Recorded at 25 frames/50 fi elds per second. (PAL discs)
or 30 frames/60 fi elds per second (NTSC discs). Generally
appropriate for TV drama programmes or animation.
Finalise
A process that makes play of a recorded CD-R, CD-RW, DVD-R, etc.
possible on equipment that can play such media. You can fi nalise,
DVD-R, DVD-R DL, DVD-RW (DVD-Video format), +R, +R DL on this
unit.
After fi nalising, the disc becomes play-only and you can no longer
record or edit. However, fi nalised DVD-RW can be formatted for
recording again.
Folder
This is a place on the hard disk, disc or SD card where groups of
data are stored together. In the case of this unit, it refers to the place
where still pictures (JPEG) and MPEG2, etc. are stored.
Formatting
Formatting is the process of making media such as DVD-RAM
recordable on recording equipment.
You can format, DVD-RAM, DVD-RW (only as DVD-Video format),
+RW, SD cards and the HDD or unused +R and +R DL on this unit.
Formatting permanently deletes all contents.
Frames and fi elds
Frames refer to the single images that constitute the video you see
on your television. Each frame consists of two fi elds.
=
+
Frame
Field
A frame still shows two fi elds, so there may be some blurring, but
picture quality is generally better.
A fi eld still shows less picture information so it may be rougher, but
there is no blurring.
Gateway
IP address of the electronic device providing Internet access. Usually
called a router IP address. (e.g., 192.168.0.1)
HDD (Hard disk drive)
This is a mass data storage device used in computers, etc. A disk
with a surface that has been treated with magnetic fl uid is spun and a
magnetic head is brought in close proximity to facilitate the reading
and writing of large amounts of data at high speed.
HDMI (High-Defi nition Multimedia Interface)
Unlike conventional connections, it transmits uncompressed digital
video and audio signals on a single cable. This unit supports high-
defi nition video output [720p (750p), 1080i (1125i), 1080p (1125p)]
from HDMI AV OUT terminals. To enjoy high-defi nition video a high
defi nition compatible television is required.
Hub
Used for connecting more than one device to the network.
IP address
A set of numbers which distinguish each PC on the network when,
for example, connected to the Internet. When using a PC in a LAN to
access a PC or device that is not included in the LAN, the IP address
is called the local IP address. (e.g., 192.168.0.10)
JPEG (Joint Photographic Experts Group)
This is a system used for compressing/decoding colour still pictures.
If you select JPEG as the storage system on digital cameras, etc.,
the data will be compressed to 1/10–1/100 of its original size. The
benefi t of JPEG is less deterioration in picture quality considering the
degree of compression.
