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, BD-Video and DVD-Video are 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

(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.
Signal Quality

This is the guide for checking the aerial 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 aerial, 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.
