Glossary
Pan&Scan/Letterbox
In general, BD-Video and DVD-Video are produced
with the intention that they be viewed on a
widescreen TV (16:9 aspect ratio), so images often
don't fit regular (4:3 aspect ratio) TVs. Two styles of
picture, "Pan & Scan" and "Letterbox", deal with this
problem.
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.
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.
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.

x.v.Colour
TM
x.v.Colour is a name for devices that are compatible
TM
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

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 TV 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
create a progressive image. Since progressive video
does not alternate scan lines like interlace, there is a
minimal amount of screen flicker.
24p
This is a progressive image recorded at a rate of 24
frames per second.
720p
In one High Definition image, 720 (750) scan lines
pass at the same time every 1/50
create a progressive image. Since progressive video
does not alternate scan lines like interlace, there is a
minimal amount of screen flicker.
