Reference

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.

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 colour

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 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.

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.

x.v.Colour™

x.v.Colour™ 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™ 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 (525i),

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.

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.
