A CD (Compact Disc) is a metal coated plastic disc. It has a diameter of 12 cm and a thickness of
about 1,2 mm. It was developed by Sony and Philips in 1985. The advantages are digital storage of
music enabling very natural sound reproduction. Beyond this, the data is stored more compact,
the handling is easy. The long lifetime of the media and the fact that usage does not decrease
quality made the CD the ideal storage media.
In the meantime, 12 different storage media have been developed from the first CD. The mostly
used are CD DA (Compact Disc Digital Audio) , CD ROM (Compact Disc Read Only Memory),
and the DVD (Digital Versatile Disc).
One can store about 74 to 80 minutes of music on a CD ( DA). This is equal to 650 to 700 MB
Signal transmission is performed touchless with a laser beam. The CD is being read from the
middle to the outer side. The data or music is recorded in a spiral from the middle to the outer side.
A CD has pits and lands, the distance is about 1,6 mm. The laser light created by a laser diode
passes different mirrors and prisms and then is focused by a lens to a laser beam. This laser beam
scans the data spiral of the CD. On the pits, the laser beam is reflected in another direction and is
detected by a photocell. The photocell transmits the signal to a microprocessor, which converts
the digital data to an audio signal. The rest is done by the sound system.
Composite Video Interface. The video signal is transmitted via a single signal line. CVBS should
only be used, if your playback device does not offer other interfaces for connection with you Xoro
TV set, as CVBS due to technical reasons delivers worst quality of all available interfaces (please
also refer to YUV, S Video, SCART and RGB). The CVBS interface can easily be identified from the
yellow colour of the RCA jack.
DivX is a new high quality video codec, which is based on MPEG 4 standard and combined with
MP3 audio. Originally, the DivX Codec was a Microsoft codec (MPEG 4 v3). The official codec
only used ASF format (no AVI) or WMV format with Windows Media Encoder 7. The official codec
had a bitrate limit, which was removed on DivX .
On the next stage of development, the codec was developed completely new and is now 100%
MPEG 4 compliant. The new codec was called DivX
4/5 and can be obtained for free at
www.divx.com. This codec is also compatible to videos encoded with the old DivX codec (DivX
3.11). Today, DivX is just a brand name for the MPEG 4 encoder/player from DivX Networks that
lives from the fame of early DivX days.
Videos encoded with DivX 4/5 are fully MPEG 4 compliant and theoretically can be played on
any MPEG 4 enabled DVD player.

DTS is a coding standard similar to Dolby Digital . DTS Digital Surround is a multichannel
surround system from Digital Theatre Systems. Similar to Dolby Digital it uses up to 5.1 channels.
Different from Dolby, the data rate can be far above 1 Mbit/sec so the sound is not compresses as
strong as in Dolby Digital® resulting in a higher sound quality.
The frequency range is from 20Hz to 20kHz at 20Bit, but the subwoofer channel only transmits
frequencies below 80Hz. The coding system also is called CAC.
