Aspect Ratio
This is the width-to-height ratio of a TV screen. A regular display has an aspect ratio of 4:3.
Wide-screen displays have an aspect ratio of 16:9, providing a bigger picture for exceptional pres-
ence and atmosphere.
Chapter
DVD titles are in turn divided into chapters which are numbered in the same way as the chapters
of a book. With DVDs featuring chapters, you can quickly find a desired scene with Chapter
Search.
Dynamic Range Control
Dolby Digital has a function for compressing the difference between the loudest and softest
sounds: Dynamic Range Control. This control ensures sounds with an increased dynamic range
are heard clearly even at low volume levels.
Linear PCM (LPCM)
This stands for Linear Pulse Code Modulation, which is the signal recording system used for
music CDs. Compared to music CDs, which feature 44.1 kHz/16-bit recordings, DVDs feature 48
kHz/16-bit – 96 kHz/24-bit recordings. The result is sound quality even higher than that provided
by music CDs.
MPEG
This stands for Moving Pictures Experts Group, and is an international video image compression
standard. Some DVDs feature digital audio compressed and recorded using this system.
Multi-Angle
With regular TV programs, although multiple cameras are used to simultaneously shoot scenes,
only images from one camera at a time are transmitted to your TV. Some DVDs feature scenes
shot from multiple angles, letting you choose your viewing angle as desired.
Multi-Audio (Multilingual Dialog)
Some DVDs feature dialog recorded in multiple languages. Dialog in up to 8 languages can be
recorded on a single disc, letting you choose as desired.
Multi-Subtitle
Subtitles in up to 32 languages can be recorded on a single DVD, letting you choose as desired.
Parental Lock
Some DVDs with violent or adult-oriented scenes feature parental lock which prevents children
from viewing such scenes. With this kind of disc, if you set this unit's parental lock level, play-
back of scenes inappropriate for children will not be possible, or these scenes will be skipped.
