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)
This is a type 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.
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.
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.
USB (Universal Serial Bus)
An interface specification to connect peripherals. Playback of
MP3, JPEG or DivX recorded to a USB device 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 to Panasonic where specific
Web sites can be viewed on this unit by connecting to the
Internet without using a PC.
x.v.Color™
x.v.Color™ 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™ with HDMI cable.
1080i
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
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 (motion-picture film). Many BD-Video movie contents
are recorded in 24 frames/second in accordance with the film
materials.
720p
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.
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.
