Sony RMT-D165A Manual

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 
double-layer and single-sided DVD is 8.5 
GB, a single-layer and double-sided DVD is 
9.4 GB, and double-layer and double-sided 
DVD is 17GB.
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 (average) 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 information is recorded in a 
multi-channel format, such as Dolby Digital, 
allowing you to enjoy a more real audio 
presence.
Furthermore, various advanced functions 
such as the multi-angle, multilingual, and 
Parental Control functions are provided with 
the DVD.

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.

File (page 50, 53)

A JPEG image recorded on a DATA CD 
(“File” is an exclusive definition for this 
player.) A single file consist of a single 
image.

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

A number that divides a track into sections to 
easily locate the point you want on a CD or 
VIDEO CD. Depending on the disc, no index 
may be recorded.

Normal (Interlace) format shows every other 
line of an image as a single “field” and is the 
standard method for displaying images on 
television. The even number field shows the 
even numbered lines of an image, and the odd 
numbered field shows the odd numbered lines 
of an image.

Compared to the Normal (Interlace) format 
that alternately shows every other line of an 
image (field) to create one frame, the 
Progressive format shows the entire image at 
once as a single frame. This means that while 
the Normal (Interlace) format can show 30 
frames/60 fields  in one second, the 
Progressive format can show 60 frames in one 
second. The overall picture quality increases 
and still images, text, and horizontal lines 
appear sharper. This player is compatible 
with the 480 progressive format.

Progressive JPEGs are used mostly on the 
internet. They are different from other JPEGs 
in that they “fade in” gradually instead of 
being drawn from top to bottom when 
displayed on a browser. This lets you view the 
image while it is being downloaded.

On a VIDEO CD with PBC (playback 
control) functions, the menu screens, moving 
pictures and still pictures are divided into 
sections called “scenes.”
