■

AES/EBU:

A digital audio connection format simi-

lar to coaxial but found mainly on professional digital

audio equipment. Balanced XLR cables are used for bet-

ter noise immunity and longer cable runs.

■

CD-R (compact disc recordable):

A type of CD

that can be recorded only once. Can be used for VCD,

CD, MP3, or JPEG.

■

CD-RW (compact disc rewritable):

A type of

CD that can be recorded over and over again. Can be

used for VCD, CD, MP3, or JPEG.

■

Chapter:

Titles on DVD-Video discs can be subdi-

vided into chapters.

■

Component video:

A video connection format

that separates the luminance (Y) and color difference

signals (P

, P

), providing better picture quality than

S-Video.

■

Composite video:

A video connection format that

combines the luminance and color signals together.

■

Direct Digital Path:

Unique Onkyo technology

that uses dedicated shielded cables to connect the digital

audio outputs, protecting the digital output signals

against the possibility of noise and interference.

■

Dolby Digital:

Once known as

AC-3,

this is the

des-

ignated surround sound format for DVD-Video, HDTV,

and select digital broadcasts (cable, satellite, over-the-

air). A Dolby Digital bitstream may contain mono, ste-

reo, Dolby Surround, or 5.1-channel audio information.

■

Dolby Pro Logic:

The decoders used in home the-

ater equipment to decode Dolby Surround material.

See

Dolby Surround.

■

Dolby Surround:

The original Dolby surround-

sound format uses matrix encoding to deliver four chan-

nels (left, right, center, and surround) over two audio

channels. Can be used with VHS video, analog TV, and

other analog stereo systems. The movie theater version is

known as

Dolby Stereo

■

Downmixing:

The process of mixing multiple

audio channels into fewer channels. For example, a 5.1-

channel surround mix can be downmixed to two chan-

nels for reproduction on stereo systems.

■

Downsampling:

The process of reducing the sam-

pling rate of digital audio.

■

DTS (Digital Theater Systems):

Like Dolby

Digital, the DTS surround-sound format offers up to 5.1-

channels

of information,

but uses less compression for a

more faithful sound.

■

DVD-Audio:

The DVD format for storing up to six

(5.1) channels of 24-bit/96 kHz digital audio or two

channels of 24-bit/192 kHz digital audio.

■

DVD-R (DVD recordable):

A type of DVD disc

that can be recorded only once. Can be used for

DVD-Video or DVD-Audio.

■

DVD-RW (DVD rewritable):

A type of DVD disc

that can be recorded over and over again. Can be used for

DVD-Video, DVD-Audio, or DVD-VR.

■

DVD-Video:

The format for storing MPEG2 video

on DVD, with interactive menus, multiple soundtracks,

subtitles, camera angles, and so on.

■

DVD-VR (DVD Video Recording):

The DVD for-

mat used by DVD recorders for storing video on

DVD-RW discs. Recorded programs can be deleted or

arranged into playlists.

■

Field:

In interlaced scanning, a ﬁeld is a single scan

of the screen. There are two ﬁelds per frame.

See

Inter-

laced Scanning

and

Progressive Scanning.

■

Frame:

An individual TV picture is called a frame.

With the NTSC color system there are 30 frames per sec-

ond (25 for PAL).

■

HD:

Abbreviation for

high deﬁnition

, as in HDTV

(high-deﬁnition TV).

■

HDMI (High Deﬁnition Multimedia Interface):

A new connection format that greatly simpliﬁes AV con-

nections by carrying uncompressed SD or HD digital

video and up to eight channels of digital audio all in one

cable.

■

i.LINK:

Another name for the IEEE 1394 connection

format. Commonly used on AV equipment. It’s a bidirec-

tional format, so connected components can talk to each

other for optimal setup and perfectly synchronized audio

transmission.

■

i.LINK Audio:

The protocol for carrying up to six

(5.1) channels and up to 24-bit/192 kHz digital audio over

i.LINK (IEEE 1394). Ofﬁcially known as the A&M Pro-

tocol—

Audio and Music Data Transmission Protocol

■

IEEE 1394:

High-speed digital connection format

used for video, audio, and computer applications.

See

also

A&M Protocol

and

i.LINK.

■

Interlaced scanning:

TV pictures are made by

scanning the screen in horizontal lines from top to bot-

tom. With Interlaced scanning, two scans (

ﬁelds

) are

used to make each picture (

frame

Contrast with

Pro-

gressive scanning.

■

JPEG (Joint Photographic Experts Group):

The acronym commonly used to refer to the compressed

ﬁle format used to store digital images.

■

LFE (low-frequency effects):

The surround-

sound channel used for low-frequency effects.

■

Linear PCM:

The uncompressed digital audio for-

mat used for audio CDs. PCM stands for

Pulse Code

Modulation.
