Glossary
Pan&Scan/Letterbox
In general, DVD-Video are produced with the intention that
they be viewed on a widescreen television (16:9 aspect
ratio), so images often don’t fit regular (4:3 aspect ratio)
televisions. Two styles of picture, “Pan & Scan” and
“Letterbox”, deal with this problem.
Progressive/Interlace
Interlace is a conventional image signal that displays the
image in 2 phases by splitting the display into odd and even
scans.
Progressive will display whole image in 1 scan. Therefore, it
will give High Definition image without flickering compared
with interlace.
Protection
You can prevent accidental deletion by setting writing
protection or deletion protection.
Router
Distinguishes the IP address assigned to each device, such
as the PC, and relays the flow of data within the network.
Sampling frequency
Sampling is the process of converting the heights of sound
wave (analog signal) samples taken at set periods into digits
(digital encoding). Sampling frequency is the number of
samples taken per second, so larger numbers mean more
faithful reproduction of the original sound.
Signal Quality
This is the guide for checking the aerial direction. The
numbered values displayed do not indicate the strength of
the signal, but the quality of the signal (the signal to noise
ratio, or “S/N”). The channels you can receive are affected
by weather conditions, seasons, time (day/night), region,
length of the cable that is connected to the aerial, etc.
Subnet mask
Enables efficient network use. A set of numbers which
identify which part of the IP address allocated to every
device connected to the router is the network portion.
Thumbnail
This refers to a miniature representation of a picture used to
display multiple pictures in the form of a list.
x.v.Colour
TM
x.v.Colour
TM
is a name for devices that are compatible with
the xvYCC format, an international standard for expanded
colour in motion pictures, and that follow the rules for signal
transmission.
You can enjoy vivid colours of wider colour ranges for a
more realistic picture when connected to a TV that supports
the x.v.Colour
TM
with HDMI cable.
1080i
In one High Definition image, 1080 (1125) alternating scan
lines pass every 1/50th of a second to create an interlace
image. Because 1080i (1125i) more than doubles current
television broadcasts of 480i (525i), the detail is much
clearer and creates a more realistic and rich image.
1080p
In one High Definition image, 1080 (1125) scan lines pass at
the same time every 1/50
th
of a second to create a
progressive image. Since progressive video does not
alternate scan lines like interlace, there is a minimal amount
of screen flicker.
720p
In one High Definition image, 720 (750) scan lines pass at
the same time every 1/50
th
of a second to create a
progressive image. Since progressive video does not
alternate scan lines like interlace, there is a minimal amount
of screen flicker.
Pan & Scan: The sides are cut off so the
picture fills the screen.
Letterbox:
Black bands appear at the
top and bottom of the picture
so the picture itself appears in
an aspect ratio of 16:9.
