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

TM

(V.1.3a with Deep Colour) technology

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

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.
