Progressive format (page 84)
Compared to the 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 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.
Region Code (page 6)
This system is used to protect the copyrights.
A region number is allocated on each DVD
player or DVD disc according to the sales
region. Each region code is shown on the
player as well as on the disc packaging. The
player can play the discs that match its region
code. The player can also play discs with the
mark. Even when the region code is not
shown on the DVD, the region limit may still
be activated.
Scene (page 9)
On a VIDEO CD with PBC (playback
control) functions, the menu screens, moving
pictures and still pictures are divided into
sections called “scenes.”
Super Audio CD (SACD) (page 6)
An SACD disc can reproduce sounds that are
extremely faithful to the original sound by
use of DSD (Direct Stream Digital)
technology. This technology utilizes a
sampling frequency of 2.8224 MHz, which is
64 times that of a conventional CD, and 1-bit
quantization that enables the disc to hold 4
times the amount of information that a
standard PCM format CD can hold. SACDs
are divided into the following types.
•
Super Audio CD (single layer disc)
This disc consists of a single HD layer*.
* High density signal layer for the Super
Audio CD
•
Super Audio CD (dual layer disc)
This disc consists of dual HD layers and is
capable of extended play over long periods.
Also, as the dual layer disc consists of dual
HD layers on one side only, you do not have
to turn the disc over during playback.
•
Super Audio CD + CD (Hybrid disc)
This disc consists of an HD layer and a CD
layer. Also, as the dual layers are on one
side only, you do not have to turn the disc
over during playback. You can play the CD
layer using a conventional CD player.
