Sony DAV-DX150 User Manual

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.

DivX video on a DATA CD/DATA DVD*.

or movie.

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.

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 of a scene, or viewpoints of the 
video camera are recorded on some DVDs.

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

A function of the DVD to limit playback of the 
disc by the age of the users according to the 
limitation 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.

to control playback.
By using menu screens recorded on VIDEO 
CDs with PBC functions, you can enjoy playing 
simple interactive programs, programs with

In contrast to the Interlace format, the 
progressive format can reproduce 50 - 60 frames 
per second by reproducing all scanning lines 
(525 lines for the NTSC system, 625 lines for the 
PAL system). The overall picture quality 
increases and still images, text and horizontal 
lines appear sharper. This format is compatible 
with the 525 or 625 progressive format.

This system is used to protect copyrights. A 
region number is allocated on each DVD system 
or DVD disc according to the sales region. Each 
region code is shown on the system as well as on 
the disc packaging. The system can play discs 
that match its region code. The system can also 
play discs with the “

region code is not shown on the DVD, the region 
limit may still apply.
