DEFINITION OF TERMS
Angle
Recorded onto some DVD’s 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’s. 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 recorded by means of digital signals.
Incorporating a new video compression technology (MPEG II) and high-density recording technology. DVD enables aesthetically 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 higher the
density at which the information can be recorded, a DVD 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
play.
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 interactively
with the TV monitor by looking at the menu shown on the TV monitor.
Subtitles
These are printed lines appearing at the bottom of the screen, which translate or transcribe the dialogue. They are recorded on the
DVD’s.
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 permit the time search feature to be used. Availability is determined by the disc’s manufacturer.)
Title Number
These numbers are recorded on DVD. 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 playback control (Version 2.0).
Dolby Digital
Many movie theatres are equipped with 5.1 channel surround systems. This same type of technology 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 decoder via the digital outputs
(either coaxial or optical).
Dolby Pro Logic
This is Dolby Laboratories’ technology to decode Dolby Surround encoded programs actively. Dolby Surround programs have four
channels of audio (Left, Center, Right and Surround) encoded into a standard 2-channel stereo signal. The rear channel is monaural.
PCM
PCM 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 format.
