Glossary
Bit rate
Value indicating the amount of video data compressed in a
DVD per second. The unit is Mbps (mega bit per second). 1
Mbps indicates that the data per second is 1,000,000 bits.
The higher the bit rate is, the larger the amount of data. How-
ever, this does not always mean that you can get higher qual-
ity pictures.
Chapter
Sections of a picture or a music piece on a DVD that are
smaller than titles. A title is composed of several chapters.
Each chapter is assigned a chapter number enabling you to
locate the chapter you want.
Dolby Digital
This sound format for movie theaters is more advanced that
Dolby Pro Logic Surround. In this format, the rear speakers
output stereo sound with an expanded frequency range and a
subwoofer channel for deep bass is independently provided.
This format is also called
“
5.1
”
because the subwoofer chan-
nel is counted as 0.1 channel (since it functions only when a
deep bass effect is needed). All six channels in this format
are recorded separately to realize superior channel separa-
tion. Furtheremore, since all the signals are processed digi-
tally, less signal degradation occurs. The name
“
AC-3
”
comes
from the fact that it is the third audio coding method to be
developed by the Dolby Laboratories Licensing Corporation.
Dolby Pro Logic Surround
As one method of decoding Dolby Surround, Dolby Pro Logic
Surround produces four channels from two-channel sound.
Compared with the former Dolby Surround system, Dolby Pro
Logic Surround reproduces left-to-right panning more natu-
rally and localizes sounds more precisely. To take full advan-
tage of Dolby Pro Logic Surround, you should have one pair of
rear speakers and a center speaker. The rear speakers out-
put monaural sound.
DTS
Digital audio compression technology that the Digital The-
ater Systems, Inc. developed. This technology conforms to
5.1-channel surround. The rear channel is stereo and there
is discrete subwoofer channel in this format. DTS provides
the same 5.1 discrete channels of high quality digital audio.
The good channel separation is realized because the all chan-
nel data is recorded discrete and processed in digital.
MPEG AUDIO
International standard coding system to compress audio digi-
tal signals authorized by ISO/IEC. MPEG 1 conforms to up to
2-channel stereo. MPEG 2 used on DVDs conforms to up to
7.1-channel surround.
