Glossary
 
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 
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 color 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 color 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.
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 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.
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 video signal standard of NTSC has 480 interlaced (i) scan lines, 
whereas progressive (p) scanning uses twice the number of scan 
lines, and this is referred to as 480p. Using progressive output, you 
can enjoy watching high resolution video.
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.
VIERA CAST
An information service unique to Panasonic where specific Web sites 
can be viewed on this unit by connecting to the Internet without using a 
PC.
x.v.Color
TM
x.v.Color
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.Color
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 TV 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.
