Sony DVP-S550D - Manual (Page 67)

Glossary
Bit rate (page 41)
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 Ae
amount of data. However, this does not always mean that
you can get higher quality pictures.
Chapter (page 5)
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 34)
The general name of technology that Sony developed to
enjoy the surround sound in a home. To enjoy the
surround sound of a movie theater in the conafort of your
own home, it simulates the sound not in a concert hall as
usual but in a movie editing studio. This player adopts
VES (Virtual Enhanced Suiroimd) system from various
DCS programs. The VES system 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 (AC-3) (page 12, 34)
Digital audio compression technolog}' that'the Dolby
Laboratories Corporation developed. This technology
conforms to 5.1-channel surround sound. The rear
channel is stereo and there is 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. The good channel
separation is realized because the all charmel data is
recorded discrete and processed in digital.
Dolby Pro Logic (page 34, 57)
Audio signal processing technology that Dolby
Laboratories Corporation developed for surround sound.
When the input signal has the surroimd component, the
Pro Logic process outputs the front, center and rear
signals. The rear charmel is monaural.
DTS (page 11)
Digital audio compression technology that the Digital
Theater 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 quahty digital audio foxmd in Dolby Digital cinema
audio systems. The good channel separation is realized
because the all channel data is recorded discrete and
processed in digital.
DVD (page 4)
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,
at 4.7 GB (Giga Byte), is 7 times that of a CD.
Furthermore, the data capacity of a dual-layer and single-
sided DVD is 8.5 GB, a single-layer and double-sided
DVD 9.4 GB, and a dual-layer and double-sided DVD 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 the variable rate coding
technology that changes the data to be allocated according
to the status of the picture.
The audio data is recorded in Dolby Digital (AC-3) as well
as in PCM, allowing you to enjoy more real audio
presence.
Furthermore, various advanced functions such as the
multi-angle, multilingual, and Parental Control functions
are provided with the DVD.
Multi-angle function (page 33)
Various angles, or viewpoints of the video camera, for a
scene are recorded on some DVDs.
Multilingual function (page 14, 32, 50)
Several languages for the soimd or sub-htles in a picture
are recorded on some DVDs.
Parental Control (page 53)

age of the users according to the limitahon level in each
country. The limitation varies from disc to disc; when it
is activated, playback is completely prohibited, violent
scenes are skipped or replaced with other scenes and so
on.
Playback Control (PBC) (page 20)
Signals encoded on VIDEO CDs (Version 2.0) to control
playback.
By using menu screens recorded on VIDEO CDs with PBC
functions, you can enjoy playing simple interactive
programs, programs with search fimctions, and so on.
