Glossary

Bitstream

This is the compressed form of digital signals. A decoder decodes

these signals into 5.1 surround and multi-channel signals.

Channel (when referring to DVD)

Sound is divided into channels based on the sound’s role.

For example, 5.1 channel

≥Front speakers– 1 left channel and 1 right channel

≥Center speaker –1 channel

≥Surround speakers–1 left channel and 1 right channel

≥Subwoofer– 1 channelk0.1 (the ratio of bass to the total amount

of sound output)

Examples as shown in the status display

(1) 1: Subwoofer signal

(not displayed if there is no subwoofer

signal)

(2) 0: No surround

1: Mono surround

2: Stereo surround (left/right)

(3) 1: Center

DIRECT NAVIGATOR

This is a list of programmes you have recorded. You can select

programmes from the list to view. The list also shows the date and

time of recording, the channel, and the titles of titled programmes.

The selected programme is played in the background, making

selection even simpler.

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 5.1-channel audio. A large amount of audio

information can be recorded on one disc using this method.

Dolby Pro Logic

A surround system where a 4-channel audio track is recorded as

2 channels and then is restored to 4 channels for play. The

surround channel is monaural.

DPOF (Digital Print Order Format)

DPOF is the standard printing format for still picture data. It is used

at a photo studio to print out the still picture data taken with a digital

camera etc. or when you print out using a domestic printer.

DTS Digital Surround

This surround system is used in many movie theaters around the

world. The separation between channels is good and the

compression ratio is low, so realistic sound effects are possible.

DTS soundtracks are produced with the assumption that all

channels will be used.

Finalize

This process allows DVD-R to be played on compatible equipment.

Frame and field

Frames are the still pictures that go together to make a moving

picture. A frame is made up of 2 fields.

≥A frame still is made up of two alternating fields, so the picture

may appear blurred, but overall quality is high.

≥A field still is not blurred, but it has only half the information of a

frame still so picture quality is lower.

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

special quality of this standard is that there is little deterioration in

picture quality in comparison to the degree of compression.

Linear PCM

This is a form of signal that has been digitized without compressing

it. CDs are recorded with 44.1 kHz/16 bit PCM, while DVDs use

PCM between 48 kHz/16 bit and 96 kHz/24 bit, allowing

reproduction of greater quality sound.

The linear PCM signals output from the DIGITAL AUDIO OUT,

OPTICAL terminal are stereo (2 channel).

LPCM sound is available when recording in XP mode.

NICAM (NICAM Broadcasting System)

This is a 2 channel sound broadcast system which in most

instances provides high quality stereo sound. Broadcasters can

also transmit two separate mono soundtracks on this system.

Pan&Scan/Letterbox

In general, DVD-Video are produced with the intention that they be

viewed on a widescreen television with an aspect ratio of 16:9.

This means you can view most material with the intended aspect

ratio on a widescreen television.

Material with this ratio will not fit onto a standard television with an

aspect ratio of 4:3. Two styles of picture, “Pan&Scan” and

“Letterbox”, deal with this problem.

Pan&Scan: The sides are cut off so the

picture fills the screen.

Letterbox: Black bands appear at the top

and bottom of the picture so the

picture itself appears in an aspect

ratio of 16:9.

Playback control (PBC)

This is a method of playing Video CDs. You can select parts to

play by using menus recorded on the disc.

PLAY LIST

This is a collection of scenes. It enables you to play these scenes

in succession or to select specific ones to play.

Programme (PRG)

The section between the point where recording is started and the

point where it is stopped.

RGB Output

[RGB] means separate Red/Green/Blue colour signals (PAL only).

If you connect a TV equipped with RGB input capability to the AV1

socket on this unit, and a decoder equipped with RGB output

capability to the AV2 socket, the TV can receive RGB signal input

from the decoder via the unit.

Sampling frequency

This is the number of samples of sound taken per second during

conversion to a digital signal. A high sampling frequency results in

a sound close to the original when played back.

S-video output

The colour and luminance signals are separated before being sent

to the television, making for greater picture clarity.

TIFF (Tag Image File Format)

A still picture data standard.

A common format for storing high quality images on digital

camera’s and other devices.
