Getting Started

Angle

Recorded onto some DVD discs are scenes which have been

simultaneously shot from a number of different angles (the

same scene is shot from the front, from the left side, from the

right side, etc.). With such discs, the ANGLE button can be

used to view the scene from different angles.

Chapter number

These numbers are recorded on DVD discs. A title is subdivid-

ed into many sections, each of which is numbered, and specif-

ic parts of video presentations can be searched quickly using

these numbers.

Digital audio output connector (Optical)

The digital audio output connector (optical) converts electrical

signals into optical signals and transfers them to the amplifier.

Consequently, it has a number of features including its immu-

nity from electrical interference from external sources and its

ability to prevent the generation of noise and its minimal effect

on the external environment.

DVD

This refers to a high-density optical disc on which high-quality

pictures and sound have been recorded by means of digital

signals. Incorporating a new video compression technology

(MPEG 2) and high-density recording technology, DVD en-

ables esthetically pleasing full-motion video to be recorded

over long periods of time (for instance, a whole movie can be

recorded).

DVD has a structure consisting of two 0.6 mm thin discs which

are adhered to each other. Since the thinner the disc, the high-

er the density at which the information can be recorded, a DVD

disc has a greater capacity than a single 1.2 mm thick disc.

Since the two thin discs are adhered to each other, there is the

potential to achieve double-sided play sometime in the future

for even longer duration of play.

Field

Half of the video information (video signal) in a frame is called

a field. With conventional TV systems, a signal frame (a single

screen) consists of two fields.

Field still

Only one field (half of the video information) is displayed on the

TV screen, so the apparent resolution is low. However, there is

no blurring on the screen.

Frame

Individual images in a video or on the TV are called frames.

Frame still

The two fields are displayed, alternately, on the TV screen, so

the image is blurry. However, the image quality is better than

field images.

Playback control

This is recorded on a Video CD (version 2.0). The scenes or

information to be viewed (or listened to) can be selected inter-

actively with the TV monitor by looking at the menu shown on

the TV monitor.

Subtitles

This is the appearance of the dialogue at the bottom of the

screen which are prerecorded on some DVD discs.

Title number

These numbers are recorded on DVD discs. When a disc con-

tains two or more movies, these movies are numbered as title

1, title 2, etc.

Track number

These numbers are assigned to the tracks which are recorded

on Video CDs and CDs. They enable specific tracks to be lo-

cated quickly.

Video CD

This contains recordings of pictures and sound whose quality

is on a par with that of videotape. This player also supports

Video CDs with playback control (version 2.0).
