JPEG (Joint Photographic Experts Group)
This is a system used for compressing/decoding color still pictures. If
you select JPEG as the storage system on digital cameras, etc., the
data will be compressed to 1/10–1/100 of its original size. The
benefit of JPEG is less deterioration in picture quality considering
the degree of compression.
LAN (Local Area Network)
A group of linked devices in a company, school or home.
Indicates the boundaries of a particular network.
Local storage
This storage area is used as a destination for sub contents for
playing virtual packages on BD-Video.
LPCM (Linear PCM)
These are a kind of PCM format.
These are uncompressed digital signals, similar to those found on
CDs.
MP3 (MPEG Audio Layer 3)
An audio compression method that compresses audio to
approximately one tenth of its size without any significant loss of
audio quality.
P4HD (Pixel Precision Progressive Processing for HD)
This is a processor which makes use of an exclusive Panasonic
algorithm. Various processing is supported, including a high-level
conversion of the TV scanning format from interlace to progressive
and a high-level conversion of standard resolution (480i or 576i)
video signal to a 1080 High Definition video signal.
Consequently, this unit is able to provide video of optimal resolution
to the connected TV.
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.
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.
PCM (Pulse Code Modulation)
This is one format for converting analog audio into digital audio,
enabling you to enjoy digital audio with no hassle.
Picture-in-picture
This is a function of BD-Video that plays the primary video and
secondary video simultaneously. For instance, the function is
capable of playing the original movie as the primary video while
playing video commentary from the film director on a small screen
as a secondary video.
Progressive/Interlace
The PAL video signal standard has 625 (or 576) interlaced (i) scan
lines, whereas progressive scanning, called 625p (or 576p), uses
twice the number of scan lines. For the NTSC standard, these are
called 525i (or 480i) and 525p (or 480p) respectively.
Using progressive output, you can enjoy the high-resolution video
recorded on media such as DVD-Video.
Your television must be compatible to enjoy progressive video.
Panasonic televisions with 625 (576)/50i · 50p, 525 (480)/60i · 60p
input terminals are progressive compatible.
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.
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.
Virtual package
This is a function of BD-Video that plays discs and other media
(Local storage) simultaneously. For instance, the function is capable
of playing sub contents (secondary video, secondary audio, and
subtitles) which are automatically recorded to other media from the
Internet or disc.
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 color in
motion pictures, and that follow the rules for signal transmission.
You can enjoy vivid colors of wider color ranges for a more realistic
picture when connected to a TV that supports the x.v.Colour
TM
with
HDMI cable.
1080i (1125i)
In one high definition image, 1080 (1125) alternating scan lines pass
to create an interlaced image. Because 1080i (1125i) more than
doubles current television broadcasts of 480i, the detail is much
clearer and creates a more realistic and rich image.
1080p (1125p)
In one high definition image, 1080 (1125) scan lines pass at the
same time to 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 (750p)
In one high definition image, 720 (750) scan lines pass at the same
time to create a progressive image. Since progressive video does
not alternate scan lines like interlace, there is a minimal amount of
screen flicker.
