Glossary

AVCHD

AVCHD is a new format (standard) for high definition video cameras

that can be used to record and play high-resolution HD images.

BD-J

Some BD-Video discs contain Java applications, and these

applications are called BD-J. You can enjoy various interactive

features in addition to playing normal video.

Bitstream

This is the digital form of multi-channel audio data (e.g., 5.1ch) before

it is decoded into its various channels.

BONUSVIEW (Final Standard Profile)

This is a BD-Video (BD-ROM version 2 Profile 1 version 1.1) that

supports the new functions such as Picture-in-picture, Secondary

Audio, and Virtual Package, etc.

DivX

DivX is a popular media technology created by DivX, Inc. DivX media

files contain highly compressed video with high visual quality that

maintains a relatively small file size.

Dolby Digital

This is a method of coding digital signals developed by Dolby

Laboratories. Apart from stereo (2ch) audio, these signals can also be

multi-channel audio.

Dolby Digital Plus

Multi-channel audio and higher audio quality is made possible using

Dolby Digital Plus. BD-Video supports up to 7.1ch output.

Dolby Digital Surround EX

This is the digital surround system developed by Dolby Laboratories.

Dolby Digital Surround EX adds a surround back channel to the traditional

5.1ch format of Dolby Digital. This creates a sound with greater presence.

Dolby Pro Logic II

Dolby Pro Logic

enables you to play stereo sources on 5.1ch.

Dolby Pro Logic IIx

Dolby Pro Logic

x enables you to play stereo and 5.1ch sources on 7.1ch.

Dolby TrueHD

Dolby TrueHD is a very high quality audio format that reproduces the

studio master audio. BD-Video supports up to 7.1ch output.

DTS (Digital Theater Systems)

This surround system is used in many movie theatres. There is good

separation between the channels, so realistic sound effects are possible.

DTS-ES

DTS-ES adds a surround back channel to the traditional 5.1ch format

of DTS. This creates a sound with greater presence.

DTS-HD

DTS-HD is a high-quality, sophisticated audio format used in movie theatres.

Previous DTS Digital Surround-compatible equipment can play DTS-HD as

DTS Digital Surround audio. BD-Video supports up to 7.1ch output.

DTS NEO:6

DTS NEO:6 enables you to play stereo and 5.1ch sources on 6.1 channels.

DTS 96/24

DTS 96/24 provides 96 kHz sound at up to 24 bits. The 96 kHz/24 bit

high frequency sounds are played through multiple channels.

Dynamic range

Dynamic range is the difference between the lowest level of sound

that can be heard above the noise of the equipment and the highest

level of sound before distortion occurs.

Dynamic range compression means reducing the gap between the

loudest and softest sounds. This means you can listen at low volumes

but still hear dialogue clearly.

Film and video

DVD-Video are recorded using either film or video. This unit can

determine which type has been used, then uses the most suitable

method of progressive output.

Film: Recorded at 25 frames per second (PAL discs) or 24 frames per

second (NTSC discs). (NTSC discs recorded at 30 frames per

second as well.) Generally appropriate for motion picture films.

Video: Recorded at 25 frames/50 fields per second. (PAL discs) or 30

frames/60 fields per second (NTSC discs). Generally appropriate

for TV drama programmes or animation.

Frames and fields

Frames refer to the single images that constitute the video you see on

your TV. Each frame consists of two fields.

≥A frame still shows two fields, so there may be some blurring, but

picture quality is generally better.

≥A field still shows less picture information so it may be rougher, but

there is no blurring.

HDMI (High-Definition Multimedia Interface)

HDMI is a digital interface for consumer electronic products. Unlike

conventional connections, it transmits uncompressed digital video and

audio signals on a single cable.

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.

Local storage

This storage area is used as a destination for sub contents for playing

virtual packages on BD-Video.

LPCM (Linear PCM)

These are uncompressed digital signals, similar to those found on CDs.

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 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.

Picture-in-picture

This is a new 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 TV must be compatible

to enjoy progressive video. Panasonic TV 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

(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.

Virtual package

Some BD-Video discs copy data to other media (local storage) and

then play the secondary video, secondary audio, and subtitles (sub

contents) simultaneously.

These functions are called virtual packages.

Sub contents are automatically recorded to other media from the disc

prior to playing the virtual package. The playback methods vary

depending on discs.

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.
