MPEG

MPEG stands for Moving Picture coding Ex-

perts Group. MPEG is a family of standards

for compressing audio-visual information.

“MPEG” standards include MPEG-1, MPEG-

2 and MPEG-4. Video CD and MP3 are based

on MPEG-1, while DVD is based on MPEG-

MPEG Multichannel

This feature expands the 5.1 channel audio

format recorded on the disc to a 7.1 channel

format. The further expansion of the 5.1 chan-

nel audio makes it easy for you to reproduce

the movie theater experience in your own

home.

NTSC (National television system

committee - U.S. version)

A black and white and color television sys-

tem format used in the U.S.A., Canada, Mexico

and Japan.

PAL (Phase Alternation by Line)

A color television system format used exten-

sively in Western Europe.

PBC

PBC stands for “Playback control” and is a

method of controlling disc play for Video CDs

(VCD). You are able to interact with the disc

through menus.

Progressive scanning

Progressive scanning displays all the horizontal

lines of a picture at one time, as a single frame.

A progressive scanning DVD unit converts the

interlaced video from DVD into progressive

format for connection to a progressive display.

It dramatically increases the vertical resolu-

tion.

RGB

An abbreviation for Red, Green and Blue.

Color monitors and color television sets dis-

play different hues by mixing these three col-

ors.

S-video

A video signal which improves picture qual-

ity over standard composite connections. Used

on Super VHS, DVD, high end TV monitors,

etc.

Track

The smallest division on SVCD, Video CD and

Audio CD discs.

Glossary

Aspect ratio

A ratio which defines the shape of the rect-

angular picture in a TV. It is the width of the

picture relative to the height. A conventional

TV picture has 4:3 in aspect ratio.

Bit rate

Shows the number of digital information

needed to play back sound for 1 second. The

bit rate is expressed in bits per second.

Bitstream

The digital form of multichannel audio data

(e.g., 5.1-channel) before it is decoded into

its various channels.

Chapter/title

Chapter is the smallest division and title is the

largest division on DVD Video. A chapter is

a division of a title and similar to a track for

Video CD or Audio CD.

Component video

Video signals with three separate channels of

information that make up the picture. There

are several types of component video, such

as R/G/B and Y/CB(PB)/CR(PR).

Composite video

A single video signal commonly used in most

consumer video products that contains all lu-

minance, color, and synchronization informa-

tion.

Dolby Digital (AC3)

A six-channel system consisting of left, cen-

ter, right, left rear, right rear and LFE (Low-

Frequency Effect channel for use with a sub-

woofer) channels. All processing is done in

the digital domain. Not all Dolby Digital discs

contain six (5.1) channels of information.

Dolby Surround/Dolby Pro Logic

Dolby Surround records four channels of front

and rear audio in two channels in a way that

allows a decoder to recover the original four

channels for playback. Because the audio is

recorded in two channels, it can be played

back by a two-channel stereo system.

Dolby Pro Logic introduces directional circuits

in decoder-side processing (increasing the level

of specific channels and lowering the level of

silent channels) for greater spatial perspec-

tive, and adds a center speaker used prima-

rily for dialog. The result is enhanced chan-

nel separation.

Down-mix

Internal stereo mix of multichannel surround

audio by a DVD player. The down-mix sig-

nals are output from stereo output connectors.

DTS

DTS stands for Digital Theater Systems, a Digital

Surround audio encoding format configured

with six (5.1) channels, similar to Dolby Digital.

It requires a decoder, either in the player or

in an external receiver. Not all DTS discs con-

tain six (5.1) channels of information.

Dynamic range

The difference between the loudest and soft-

est sounds.

Group

The largest division on DVD AUDIO.

Interlaced scanning

In a conventional video system, a picture is

shown on the display monitor in between lines

of two halves. The Interlaced scanning system

places lines of the second half of the picture

in-between lines of the first half of the picture.

JPEG

A popular file format for still image compres-

sion and storage. JPEG stands for Joint Pho-

tographic Experts Group.

There are three sub-types of the JPEG format

as follows.

• baseline JPEG: used for digital cameras, the

web, etc.

• progressive JPEG: used for the web

• lossless JPEG: an old type, rarely used now

Linear PCM audio

PCM stands for “pulse code modulation.” Lin-

ear PCM is the usual method for digitally en-

coding audio without compression, and is used

for the audio tracks on DVD Video discs, Au-

dio CDs, etc.

MLP

MLP stands for “Meridian Lossless Packing.”

A lossless audio compression system that can

completely recreate the PCM signal.

MP3

MP3 is an audio data compression format,

which stands for MPEG-1 Audio Layer 3. Using

MP3, you can achieve a data reduction of

about 1:10.
