CVBS
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 avail-
able 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.
Dolby Digital
® 5.1
Dolby Digital ® 5.1 is a system for transmission and storage of 5.1 channel sound on digital
media as DVD, digital TV and satellite transmission. Different from the codecs Dolby Sur-
round
® and Pro Logic ® who do not work with channel separation to encode the surround
sound in a stereo recording, Dolby Digital ® is a discrete system where the different audio
channels keep completely separated during encoding and decoding. Dolby Digital 5.1 is
industry standard for coding of DVD movies with surround sound.
DSP
Digital Signal Processor. Microprocessor for digital processing of signals. Virtual Surround
for example is created with a DSP.
DTS
®
DTS ® is a coding standard similar to Dolby Digital ® . DTS Digital Surround ® is a multichannel
surround system from Digital Theater 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 channels only trans-
mits frequencies below 80Hz. The coding system also is called CAC.
DVD
The DVD (Digital Versatile Disk) was introduced in 1995 and is a storage media with a large
capacity.
While a standard CD can store 650 MB of data, the DVD can store up to 9 GB. Especially
when it comes to video playback, a large storage capacity is important. Beyond its high ca-
pacity, the consumer enjoys high quality video and audio. A DVD can store up to 8 different
audio streams, so in best case, the movie can be watched in 8 different languages.
GUI
Graphic User Interface. See OSD.
HDCD
Pacific Microsonics has developed a digital audio technology using the full potential of a CD.
The HDCD process (High Definition Compatible Digital) is a patented coding and decoding
process transporting the complete details of a high resolution “master recording” to a CD.
There were several attempts to improve the sound quality of CD’s, but none which could be
compared to HDCD process.
