field to field. The end result is an image that
is higher in quality when compared to the
Interlace format.
• Film based software conversion
Film shows an image by displaying an entire
image at 24 frames per second. When you
watch a film on television, the television
displays every other line of the frame as a
field, thus reducing information level and the
clarity of the film image.
This player solves this problem by increasing
the speed at which the frames are displayed,
consecutively showing 2 identical frames in
the time that it normally takes to show one
frame. The end result is that the 24 frames per
second are increased to 50 frames per second,
which is the speed at which Progressive video
signals are shown.
This not only allows film to be shown in a
frame based format, it also increases the
clarity and sharpness which is unique to
Progressive format images.
Progressive format (PAL) (page 77)
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 25 frames (50
fields) in one second, the Progressive format
can show 50 frames in one second. The
overall picture quality increases and still
images, text, and horizontal lines appear
sharper.

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 (page 6)
A Super Audio CD 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. Super
Audio CDs 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.
