Sony DVP-FX1 - Manual (Page 108)

108 Additional Information
Dolby Pro Logic (page 92)
Audio signal processing technology that
Dolby Laboratories Corporation
developed for surround sound. When
the input signal contains a surround
component, the Pro Logic process
outputs the front, center and rear
signals. The rear channel is monaural.
DTS (page 8, 93)
Digital audio compression technology
that Digital Theater Systems, Inc.
developed. This technology conforms to
5.1-channel surround. The rear channel
is stereo and there is a discrete
subwoofer channel in this format. DTS
provides the same 5.1 discrete channels
of high quality digital audio. Good
channel separation is realized because
all of the channel data is recorded
discretely and processed in digital.
DVD (page 6)
A disc that contains up to 8 hours of
moving pictures even though its
diameter is the same as a CD.
The data capacity of a single-layer and
single-sided DVD is 4.7 GB (Giga Byte)
which is 7 times that of a CD. The data
capacity of a dual-layer and single-sided
DVD is 8.5 GB, a single-layer and
double-sided DVD is 9.4 GB, and a dual-
layer and double-sided DVD is 17 GB.
The picture data uses the MPEG 2
format, one of the worldwide standards
of digital compression technology. The
picture data is compressed to about 1/40
of its original size. The DVD also uses a
variable rate coding technology that
changes the data to be allocated
according to the status of the picture.
Audio data is recorded in Dolby Digital
as well as in PCM, allowing you to enjoy
a more real audio presence.
Bit rate (page 64)
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, the larger the amount of data.
However, this does not always mean
that you can get higher quality pictures.
Chapter (page 7)
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) (page 60)
The general name of technology that
Sony developed to enjoy surround
sound in a home. It simulates the sound
of a movie editing studio instead of the
usual concert hall so that you can enjoy
the surround sound of a movie theater
in the comfort of your own home. The
VES (Virtual Enhanced Surround)
system contained in DCS programs can
create the sound image of virtual rear
speakers from the sound of the front
speakers (L, R) without using actual rear
speakers.
Dolby Digital (page 22, 92)
Digital audio compression technology
developed by Dolby Laboratories
Corporation. This technology conforms
to 5.1-channel surround sound. The rear
channel is stereo and there is a discrete
subwoofer channel in this format.
Dolby Digital provides the same 5.1
discrete channels of high quality digital
audio found in Dolby Digital cinema
audio systems. Good channel separation
is realized because all of the channel
data is recorded discretely and
processed in digital.
