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 devices 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 devices equipped for this purpose (in particular large screen televisions 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 device 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 transmission, YUV is comprised of three separated image signals:
•the brightness signal "Y" and
•the two colour diferential signals "U/Pb" and "V/Pr"
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 encrypted (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 device (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 encrypted signal back into music and/or sound.
The Silvercrest KH 6521/KH 6522 DVD player is equipped 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 information 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 additional 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 location 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 and NTSC?
PAL
PAL is the abbreviation for "Phase Alternation Line". PAL is the mid and west Europe (Exception: France) customary and widest distributed 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.
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.
