Sony MHC-GNZ888D Manual Do Utilizador

A disc that contains up to 8 hours of 
moving pictures even though its diameter 
is the same as a AUDIO CD. 
The data capacity of a single-layer and 
single-sided DVD VIDEO, at 4.7 GB 
(Giga Byte), is 7 times that of an AUDIO 
CD. Furthermore, the data capacity of a 
dual-layer and single-sided DVD VIDEO 
is 8.5 GB, a single-layer and double-sided 
DVD VIDEO 9.4 GB, and a dual-layer 
and double-sided DVD VIDEO 17 GB. 
The picture data uses the MPEG 2 format, 
one of the worldwide standards for digital 
compression technology. The picture data 
is compressed to about 1/40 of its original 
size. The DVD VIDEO also uses 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 as well as in PCM, allowing you to 
enjoy more realistic audio presence.
Furthermore, various advanced functions 
such as the multi-angle, multilingual, and 
Parental Control functions are provided 
with the DVD VIDEO. 

A DVD-RW is a recordable and 
rewritable disc that is the same size as a 
DVD VIDEO. The DVD-RW has two 
different modes: VR mode and Video 
mode. DVD-RWs created in Video mode 
have the same format as a DVD VIDEO, 
while discs created in VR (Video 
Recording) mode allow the contents to be 
programmed or edited.

A DVD+RW (plus RW) is a recordable 
and rewritable disc. DVD+RWs use a 
recording format that is comparable to the 
DVD VIDEO format.

DVD VIDEOs can be classified as Film 
based or Video based software. Film 
based DVD VIDEOs contain the same 
images (24 frames per second) that are 
shown at movie theaters. Video based 
DVD VIDEOs, such as television dramas 
or sitcoms, displays images at 30 frames 
(or 60 fields) per second.

The Interlace format is the NTSC 
standard method for displaying TV 
images at 30 frames per second. Each 
frame is scanned twice-alternately 
between the even numbered scanning 
lines and then odd numbered scanning 
lines, at 60 times per second.

Various angles, or viewpoints of the video 
camera, for a scene are recorded on some 
DVD VIDEOs.

Several languages for the sound or 
subtitles in a picture are recorded on some 
DVD VIDEOs.
