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. However, this
does not always mean that you can get
higher quality 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.
Digital Cinema Sound (DCS)
This is the generic name of the surround
sound produced by digital signal processing
technology developed by Sony. Unlike
previous surround sound fields mainly
directed at the reproduction of music,
Digital Cinema Sound is designed
specifically for the enjoyment of movies.
Dolby Digital
This sound format for movie theaters is
more advanced than 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 channel 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 separation. Furthermore,
since all the signals are processed digitally,
less signal degradation occurs.
Self-diagnosis Function
(When letters/numbers appear in the
display)
The self-diagnosis function is activated to
prevent the system from malfunctioning. In
this case a five-character service number
(e.g., C 13 00) with a combination of a letter
and digits appears on the screen and the
front panel display. Refer to the following
table.
