Composite video

Video signal or FBAS signal; thereby it involves an image signal, in which

colour and brightness information are included at the same time.

Progressive scan

In the normal way TV appliances and Video projectors are controlled with so

called "Half images". Thereby clearly visible line structures develop. Contrary

to this, Progressive Scan denotes the output of full images (with this DVD player,

at the output YPbPr) Progressive Scan signals can only be processed by play-

back appliances equipped for this purpose (in particular large screen tele-

visions and projectors). The image quality as opposed to traditional image

signals is considerably higher.

YUV (component video out)

YUV indicates the component signal, which with this appliance is available

at the output YPbPr in the form of so called "Half images"; as a rule this is the

best signal for the control of large screen televisions and projectors, which

can not process Progressive Scan signals. As with the RGB image transmis-

sion, YUV is comprised of three separated image signals:

• the brightness signal "Y" and

• the two colour difference signals "Pb/Cb" and "Pr/Cr"

Half images (Interlace)/Full images (Progressive Scan)

A standard television image is comprised of 576 visible lines; at first all odd

and then all even image lines are displayed alternatively, thus each displays

a half image. Thereby only 25 full images (50 Half images) can be displayed

per second. This technique is designated as "Interlace" format.

Contrary to this with the so called progressive or "Progressive Scan" format

all image lines are displayed every time, that is to say 60 full images per

second are displayed. Thereby increasing the total quality of the images, still

images and text for example appear sharper.

HDMI

HDMI is short for "High Definition Multimedia Interface" and refers to a 19

contact interface for complete digital transmission of audio and video data.

With its high bandwidth HDMI handles all known today home electronics

digital video and audio formats. HDMI transmits audio data up to frequencys

of 192 kHz with text widths of up to 24 Bit on up to 8 channels. Thus not

only all of today's image and sound formats introduced into home electronics

including HDTV (up to the highest present resolution of 1080i) are transmitted

without loss of quality but also future formats with yet higher resolutions.

Decoder

The sound on DVDs with home theatre sound is saved on the DVD in encryp-

ted (encoded) form. Different encryption formats exist for several purposes,

for example AC-3 for the playback of Dolby Digital Surround Sound.

In order to playback encrypted sound, the playback appliance (i.e. the DVD

player) and/or the audio component connected to it (for example Surround

system) must be equipped with a so called decoder, which converts the en-

crypted signal back into music and/or sound.

The Silvercrest KH 6517/KH 6518 DVD player is equiped with an AC-3

Decoder (for Dolby Digital 5.1 Surround Sound signals).

Dolby Surround

Dolby Surround is an analogue sound format, by which the two channels

of a stereo sound signal are used in order to accommodate room sound in-

formation for further channels. Dolby Surround decoders convert the signals

back into sound or music and send the audio to two additional speakers that

are situated behind the listener.

Dolby Prologic

In comparison to Dolby Surround sound format, with Dolby Prologic an addi-

tional channel in the stereo signal is used; this is the so called "Centre" channel.

The corresponding centre loudspeaker is to be situated in the middle between

the stereo loudspeakers. The deepest sounds are fed to a bass loudspeaker,

the so called "Subwoofer". The subwoofer can be placed in any desired loca-

tion in the room; the logic for this is that the bass sounds that the subwoofer

puts out can scarcely be localized exactely by the human ear

Dolby Digital (5.1)

Dolby Digital, also designated as AC3, is a digital sound format, by which up

to six seperate audio channels can be transported. With most of the current

DVDs, the sound is stored in the so called "Dolby Digital 5.1" format; the "5"

in the name "5.1" stands for the three front and two rear surround sound

channels, the "1" stands for the subwoofer channel.

DTS

DTS is the abbreviation for "Digital Theatre System" and denotes one of the

most common surround sound formats for DVDs. As with Dolby Digital 5.1,

DTS uses three front and two rear surround sound channels as well as a bass

sound channel.

What are PAL, NTSC and SECAM?

PAL

PAL is the abbreviation for "Phase Alternation Line". PAL is the mid and west

Europe (Exception: France, see the heading "SECAM") customary and most

wide spread colour television standard.

NTSC

NTSC is the abbreviation for "National Television System Committee". NTSC

is a colour television standard that is primarily used in the USA and Japan.

SECAM

SECAM is the abbreviation for the french "système en couleur avec mémoire".

SECAM is the customary colour television norm in France and many east

European countries and at present still the most widely spread system in

those countries.

Audio CDs

Audio CDs contain exclusively audio data; they are also available in 8 cm

and 12 cm (Diameter) formats. The playback duration for the audio data

stored on them amounts to 20 minutes (8 cm format) and/or 74 minutes

(12 cm format). Audio data is stored on audio CDs in CDA format.

MP3

MP3 denotes a process and/or format developed by the Fraunhofer Institute

for the compression of audio data. In the MP3 format compressed music pieces

are only a fraction of their original size, which, for example, on CD-Rs/CD-RWs

allows for storage of a considerably greater volume of music than on com-

mercially available audio CDs, on which audio data is stored in the CDA

format.

WMA

WMA ("Windows® Media Audio") is a data format developed by Microsoft®

for audio data.

JPEG

JPEG ("Joint Photographics Expert Group") denotes a wide spread graphic

format, developed by the organization with the same name, with which image

data of the colour and grey scales are compressed.
