RQT9431
LAN (Local Area Network)
A group of linked devices in a company, school or home. Indicates
the boundaries of a particular network.
LPCM (Linear PCM)
These are uncompressed digital signals, similar to those found on CDs.
MPEG2 (Moving Picture Experts Group)
A standard for effi ciently compressing and expanding colour video.
MPEG2 is a compression standard used for DVD and satellite based
digital broadcasting.
MPEG-4AVC/H.264
A standard for effi ciently compressing and expanding colour video.
MPEG-4AVC/H.264 is an encoding method used for recording of the
high defi nition videos.
MP3 (MPEG Audio Layer 3)
An audio compression method that compresses audio to
approximately one tenth of its size without any considerable loss of
audio quality.
Pan&Scan/Letterbox
In general, DVD-Video is produced with the intention that they be
viewed on a widescreen television (16:9 aspect ratio), so images
often don’t fi t regular (4:3 aspect ratio) televisions. Two styles of
picture, “Pan&Scan” and “Letterbox”, deal with this problem.
Pan&Scan: The sides are cut off so the picture
fi lls 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
defi nition image without fl ickering 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 fl ow of data within the network.
RGB
This refers to the three primary colours of light, red (R), green (G),
and blue (B) and also the method of producing video that uses them.
By dividing the video signal into the three colours for transmission,
noise is reduced for even higher quality images.
Sampling frequency
Sampling is the process of converting the heights of sound wave
(analogue 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 satellite dish 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 satellite dish, etc.
Subnet mask
Enables effi cient 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.
VIERA CAST
An information service unique to Panasonic where specifi c Web sites
can be viewed on this unit by connecting to the Internet without using
a PC.
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 defi nition 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 defi nition image, 1080 (1125) scan lines pass at the
same time every 1/50th 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 fl icker.
24p
This is a progressive image recorded at a rate of 24 frames per second.
720p
In one high defi nition image, 720 (750) scan lines pass at the same
time every 1/50th 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 fl icker.
