Glossary
JPEG (Joint Photographic Experts Group)
This is a system used for compressing/decoding colour 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 BD-Live on BD-Video.
LPCM (Linear PCM)
These are a kind of PCM format.
These are uncompressed digital signals, similar to those found
on CDs.
MPEG2 (Moving Picture Experts Group)
A standard for efficiently compressing and expanding colour
video.
MPEG2 is a compression standard used for DVD and satellite
based digital broadcasting.
MPEG-4 AVC/H.264
A standard for efficiently compressing and expanding colour
video. MPEG-4 AVC/H.264 is an encoding method used for
recording of the high definition videos.
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.
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 analogue 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.

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.
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 (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.
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.
USB (Universal Serial Bus)
An interface specification to connect peripherals. Playback of
MP3, JPEG, or DivX recorded to a USB memory by PC or
other equipment, or JPEG in the Panasonic digital camera or
similar connected via USB connection cable is possible with
this unit.
VIERA CAST
An information service unique with Panasonic where specific
Web sites can be viewed on this unit by connecting to the
Internet without using a PC.
x.v.Colour TM
x.v.Colour is a name for devices that are compatible with the
TM
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 with HDMI cable.
TM
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.
