• 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 3 identical frames
followed by 2 identical frames in the time that
it normally takes to show 2 consecutive
frames. The end result is that the 24 frames
per second are increased to 60 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 (page 71)
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 25 or
30 frames (50-60 fields) in one second, the
Progressive format can show 50-60 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 (525) progressive
format.
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)
Super Audio CD is a new high-quality audio
disc standard where music is recorded in the
DSD (Direct Stream Digital) format
(conventional CDs are recorded in the PCM
format). The DSD format, using a sampling
frequency 64 times higher than that of a
conventional CD, and with 1-bit quantization,
achieves both a wide frequency range and a
wide dynamic range across the audible
frequency range, and so provides music
reproduction extremely faithful to the
original sound.
Types of Super Audio CDs
There are two types of discs, depending on
the Super Audio CD layer and CD layer
combination.
• Super Audio CD layer: A high-density
signal layer for Super Audio CD
• CD layer

: A layer that is readable by a
conventional CD player
