File

A JPEG image recorded on a DATA CD/DATA DVD. (“File” is an exclusive definition for this system.) A single file consists of a single image or movie.

Film based software, Video based software

DVDs can be classified as film based or video based software. Film based DVDs contain the same images (24 frames per second) that are shown at movie theaters. Video based DVDs, such as television dramas or sit-coms, displays images at 30 frames (or 60 fields) per second.

HDMI (high-definition multimedia interface)

HDMI is an interface that supports both video and audio on a single digital connection, allowing you to enjoy high quality digital picture and sound. The HDMI specification supports HDCP (high-bandwidth digital contents protection), a copy protection technology that incorporates coding technology for digital video signals.

Interlace format (Interlaced scanning)

The Interlace format is the NTSC standard method for displaying TV images at 30 frames per second. Each frame is scanned twice - alternately between the even numbered scanning lines and then odd numbered scanning lines, at 60 times per second.

Mica-reinforced-cellular-diaphragm

The Mica-reinforced-cellular-diaphragm is made of a light weight and highly rigid composite material that consists of Mica flake and synthetic fiber.

It is constructed with layers of Mica flake. This construction realizes diaphragm with low density and high rigidity at the same time.

In this system, a Mica-reinforced-cellular- diaphragm is used for the subwoofer.

MPEG audio

A coding system to compress digital audio signals. MPEG-1 is used for MP3 (MPEG-1 Audio Layer-3). MPEG-2 is used for one of the audio format of DVD.

Multi-angle function

Various angles of a scene, or viewpoints of the video camera are recorded on some DVDs.

Multilingual function

PCM (Pulse Code Modulation)

A method for converting analog audio to digital audio. It is used for the Compact Disc (CD) audio format.

Playback Control (PBC)

 

Signals encoded on VIDEO CDs (Version 2.0)

 

to control playback.

 

By using menu screens recorded on VIDEO

 

CDs with PBC functions, you can enjoy playing

 

simple interactive programs, programs with

 

search functions, and so on.

 

Additional

Progressive format

 

(sequential scanning)

 

In contrast to the Interlace format, the

 

progressive format can reproduce 50 - 60 frames

Information

per second by reproducing all scanning lines

 

(525 lines for the NTSC system). The overall

 

picture quality increases and still images, text

 

and horizontal lines appear sharper.

 

Region Code

 

This system is used to protect copyrights. A

 

region number is allocated on each DVD system

 

or DVD disc according to the sales region. Each

 

region code is shown on the system as well as on

 

the disc packaging. The system can play discs

 

that match its region code. The system can also

 

play discs with the “ ALL ” mark. Even when the

 

region code is not shown on the DVD, the region

 

limit may still apply.
