Glossary
Analog audio:
An electrical signal that directly represents sound. In contrast, digital audio can also be an electrical signal, but is an indirect representation of sound. See also Digital audio.
Aspect ratio:
The width of a TV screen relative to it is height. Conventional TVs are 4:3 (i.e., the screen is almost square). Widescreen models are 16:9 (the screen is almost twice as wide as its height)
AUDIO OUT jacks:
Jacks on the back of the DVD System that send audio to another system (TV, Stereo, etc.)
Bit rate:
The amount of data used to hold a given length of music; measured in kilobits per seconds, or kbps. Or, the speed at which you record.Generally, the higher the bit rate, or the higher the recording speed, the better the sound quality. However, higher bit rates use more space on a disc.
Chapter:
Just as a book is split up into several chapters, a title on a DVD disc is usually divided into chapters. See also Title.
Digital audio:
An indirect representation of sound using numbers. During recording, the sound is measured at discrete intervals (44, 100 times a second for CD audio) by an
Disc menu:
A screen display prepared for
allowing of selection of images, sound, subtitle,
Dolby® Digital:

Multichannel:
DVD is specified to have each sound track constitute one sound field. Multi- channel refers to a structure of sound tracks having three or more channels.
Parental control:
A function of the DVD to limit playback of the disc by the age of the users according to the limitation level in each country. The limitation varies from disc to disc; when it is activated, playback will be prohibited if the software’s level is higher than the
PBC (Video CD only): (Playback Control)
This function enables you to play back interactive software using a menu screen. See also Title.
PCM:
(Pulse Code Modulation)
PCM is a format that converts audio into digital data. It is mainly used for Audio CDs and DAT. This unit can play back sounds as realistic as
possible by converting even com- pressed Dolby Digital and MPEG audio to PCM.
Progressive scan:
It displays all the horizontal lines of a picture at one time, as a signal frame. This system can convert the interlaced video from DVD into progressive format for connection to a progressive display. It dramatically increases the vertical resolution.
Region code:
Regions associate discs and players with particular areas of the world. This unit will only play back
discs that have compatible region codes. You can find the region code of your unit by looking on the rear panel. Some discs are compatible with more than one region (or all regions).
Sampling frequency:
The rate at which sound is
measured by a specified interval to turn it into digital audio data. The number of samples in one second is defined as the sampling frequency. The higher the rate is, the better the possible sound quality.
Title:
(DVD)
A collection of chapters on a DVD. See also chapter.
(Video CD)
The contents of a Video CD. When playing back a Video CD with the PBC function, the title menu will
appear automatically.
Track:
Audio CDs and Video CDs use tracks to divide the contents of a
disc. The DVD equivalent is called a chapter. See also Chapter.
