Film based software, Video based
software (page 19)
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 theatres.
Video based DVDs, such as television
dramas or sit-coms, displays images at 30
frames/60 fields (25 frames/50 fields) per
second.
HDMI (High-Definition Multimedia
Interface)
HDMI is an interface that supports both video
and audio on a single digital connection. The
HDMI connection carries standard to high
definition video signals and multi-channel
audio signals to AV components such as
HDMI equipped TVs, in digital form without
degradation.
Since the video signals are compatible with
the current DVI (Digital Visual Interface)
format, HDMI jacks can be connected to DVI
jacks by way of an HDMI-DVI converter
cord. The HDMI specification supports
HDCP (High-bandwidth Digital Contents
Protection), a copy protection technology that
incorporates coding technology for digital
video signals.
MPEG audio (page 21, 78)
International standard coding system used to
compress audio digital signals authorized by
ISO/IEC. MPEG 1 conforms to up to 2-
channel stereo. MPEG 2, used on DVDs,
conforms to up to 7.1-channel surround.
Normal (Interlace) format (page 19)
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.
Progressive format (page 19)
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 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
525 or 625 progressive format.
Progressive JPEG
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.
Super Audio CD (page 5)
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.
