AVCHD is a new format (standard) for high definition video cameras 
that can be used to record and play high-resolution HD images.

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.

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 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.

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.

Multi-channel audio and higher audio quality is made possible using 
Dolby Digital Plus. BD-Video supports up to 7.1ch output.

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 enables you to play stereo sources on 5.1ch.

Dolby Pro Logic IIx enables you to play stereo and 5.1ch sources on 7.1ch.

Dolby TrueHD is a very high quality audio format that reproduces the 
studio master audio. BD-Video supports up to 7.1ch output.

This surround system is used in many movie theatres. There is good 
separation between the channels, so realistic sound effects are possible.

DTS-ES adds a surround back channel to the traditional 5.1ch format 
of DTS. This creates a sound with greater presence.

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 enables you to play stereo and 5.1ch sources on 6.1 channels.

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 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.

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 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 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.

This storage area is used as a destination for sub contents for playing 
virtual packages on BD-Video.

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.

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.

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 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.

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.

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.

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.

This is a progressive image recorded at a rate of 24 frames per second.

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.
