4 TERMINOLOGY

Terminology

Since they share some of the characteristics and

technology of CD players, many of the terms and

operational concepts used in a DVD player are

similar to what you may be familiar with from CD

players and changers, or older video disc formats

such as Laser Disc. However, if this is your first

DVD product, some of the terms used to describe

the features of a DVD player may be unfamiliar.

The following explanations should solve some of

the mysteries of DVD, and help you to enjoy all

the power and flexibility of the DVD format and

the DVD.

With the arrival of DVD, disc data capacity has

increased dramatically. On a DVD Video disc most

of this capacity is taken up by MPEG 2 video and

the multichannel movie soundtrack in Dolby

Digital and/or DTS. This information is compressed.

Aspect Ratio: This is a description of the width

of a video image in relation to its height. A con-

ventional video screen is four units wide for every

three units of height, that’s why the ratio is called

”4:3”. Newer wide aspect ratio video displays

are 16 units wide for every nine units of height,

making them more like the screen in a movie the-

ater. The program material on a DVD may be

recorded in either format and, in addition, you

may configure the DVD to play back in either for-

mat, depending on the features recorded on a

disc.

Title: For a DVD, a title is defined as an entire

movie or program.There can be as many chapters

within a title as the producers decide to include.

Most discs include only one title, but some may

have more than one, to give you a “Double

Feature” presentation.

Chapter: DVD programs are divided into chap-

ters and titles. Chapters are the sub-sections pro-

grammed into a single title on a disc. Chapters

may be compared to the individual tracks on an

audio CD.

RGB Video: This is a new form of video signal

that eliminates many of the artifacts of traditional

composite video signals by splitting the signal

into the three fundamental colors Red, Green and

Blue (RGB). With an RGB connection (via SCART),

you will see greater picture resolution and elimi-

nate many picture imperfections such as the

moiré patterns often seen on checkered pat-

terned cloths. However, in order to benefit from

RGB video, you must have a video display with an

RGB compatible SCART input.

Progressive scan: DVD offers progressive scan

video outputs for use with compatible high-reso-

lution televisions and projectors. Before DVD, no

consumer medium could store, transmit or display

video with full resolution. To conserve bandwidth,

analog compression (interlacing) is employed: first

the odd-numbered lines of a frame are displayed,

followed by the even-numbered lines. The result is

that only half of the video image is drawn at one

time; the viewer's brain must reassemble the com-

plete image. This is acceptable, if the monitor is

not too large and if there is not too much motion

in the image. Large displays and fast-moving

images reveal the limitations of this system.

Thanks to DVD's immense data capacity, images

are now stored intact (progressively), so that all

the lines in each frame (odd and even) are shown

at the same time. But because most TV's cannot

handle a progressive signal, all current DVD play-

ers generate an interlaced output for compatibili-

ty. Now, the Harman Kardon DVD is among the

select few DVD players with true progressive scan

video output (NTSC and PAL) for use with com-

patible TV's and CRT projectors and with all plas-

ma, LCD and DLP display devices via the compo-

nent video output. The result is 40% greater light

output than a conventional TV and a stunningly

detailed high definition image, along with an

almost complete absence of visible scanlines and

motion artifacts. Of course, traditional Y/Pr/Pb

component video, SCART, S-Video and composite

video outputs are included for use with conven-

tional televisions and projectors.

Multiple Angle: DVDs have the capability to

show up to four different views of the same

scene in a program. When a disc is encoded with

multiple-angle information, pressing the Angle

button will enable you to switch between these

different views. Note that at present, few discs

take advantage of this capability and, when they

do, the multiple-angle technology may only be

present for short periods of time within the disc.

Producers will usually insert some sort of icon or

graphic in the picture to alert you to the availabil-

ity of multiple viewing angles.

Reading: This is a message that you will see

after you´ve loaded the disc and the tray has

closed. It refers to the fact that the player must

first examine the contents of the disc to see if it is

a CD or DVD, and then extract the information

about the type of material on the disc, such as

languages, aspect ratios, subtitles, number of

titles and more. The slight delay while the con-

tents of the disc are read is normal.

Resume: The operation of the Stop Button on

the DVD works differently from what you are

used to on CD players. On a traditional CD player,

when you press the Stop button, the unit does

just that: it stops playback. On a CD player, when

you press the start button again, the disc starts

from the beginning. With the DVD, however, you

have two options when playing DVD discs.

Pressing Stop once will stop playback, but it actu-

ally puts the unit in the Resume mode. This

means that you can turn the machine off and,

when you press play the next time, the disc will

resume or continue from the point on the disc

where the Stop button was pressed. This is help-

ful if you are watching a movie and must inter-

rupt your viewing session but wish to pick up

where you left off. Pressing the Stop button twice

will stop the machine in a traditional manner

and, when the disc is played again, it will start

from the beginning.

In resume mode, the cover of the DVD will be

displayed, if available. Otherwise, the

Harman Kardon screen will appear.
