Definition of Terms

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 dif- ferent angles.

Chapter Number

These numbers are recorded on DVD discs. A title is subdivided into many sections, each of which are numbered, and specific parts of video presentations can be searched quickly using these numbers.

DVD

This refers to a high-density optical disc on which high-quality pictures and sound have been re- corded by means of digital signals. Incorporat- ing a new video compression technology (MPEG II) and high-density recording technol- ogy. DVD enables aesthetically pleasing full- motion video to be recorded over long periods of time (for instance, a whole movie can be re- corded).

DVD has a structure consisting of two 0.6-mm thin discs, which are adhered to each other. Since the thinner the disc, the higher the density at which the information can be recorded, a DVD disc has a greater capacity than a single 1.2

mmthick disc. Since the two thin discs are ad- hered to each other, there is the potential to achieve double-sided play sometime in the fu- ture for even longer duration play.

Playback Control

This is recorded on a Video CD (Version 2.0). The scenes or information to be viewed (or lis- tened to) can be selected interactively with the TV monitor by looking at the menu shown on the TV monitor.

Subtitles

These are printed lines appearing at the bot- tom of the screen, which translate or transcribe the dialogue. They are recorded on the DVD discs.

Time Number

This indicates the playtime, which has elapsed from the start of a disc or a title. It can be used to find a specific scene quickly. (Not all discs per- mit the time search feature to be used. Avail- ability is determined by the disc’s manufacturer.)

Title Number

These numbers are recorded on DVD discs. When a disc contains 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 AudioCDs. They enable specific tracks to be located 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 play- back control (Version 2.0).

DolbyDigital

Many movie theatres are equipped with 5.1 chan- nel surround systems. This same type of tech- nology is available to you in your home. To enjoy full 5.1-channel surround, your DVD player must be connected to an external Dolby Digital de- coder via the digital outputs (either coaxial or optical).

DolbyPro Logic

This is Dolby Laboratories’ technology to de- code Dolby Surround encoded programs ac- tively. Dolby Surround programs have four chan- nels of audio (Left, Center, Right and Surround) encoded into a standard 2-channel stereo sig- nal. The rear channel is monaural.

LPCM

LPCM stands for Pulse Code Modulation and is digital audio.

MPEG

Short for Moving Picture Experts Group. This is an international standard for compression of moving images. On some DVDs digital audio has been compressed and recorded in this for- mat.
