Glossary
AVCHD
The AVCHD format is a high-definition digital 
video camera format used to record SD 
(standard definition) or HD (high definition) 
signals of either the 1080i specification* or the 
720p specification** on DVDs, using efficient 
data compression coding technology. The 
MPEG-4 AVC/H.264 format is adopted to 
compress video data, and the Dolby Digital or 
Linear PCM system is used to compress audio 
data. The MPEG-4 AVC/H.264 format is 
capable of compressing images at higher 
efficiency than that of the conventional image 
compression format. The MPEG-4 AVC/H.264 
format enables a high definition (HD) video 
signal shot on a digital video camera recorder to 
be recorded on DVD discs in the same way as it 
would be for a standard definition (SD) 
television signal.
* A high definition specification that utilizes 1080 
effective scanning lines and the interlace format.
** A high definition specification that utilizes 720 
effective scanning lines and the progressive format.
BD-J application
The BD-ROM format supports Java for 
interactive functions.
“BD-J” offers content providers almost 
unlimited functionality when creating 
interactive BD-ROM titles.
BD-R
BD-R (Blu-ray Disc Recordable) is a 
recordable, write-once Blu-ray Disc, available 
in the same capacities as the BD below. Since 
contents can be recorded and cannot be 
overwritten, a BD-R can be used to archive 
valuable data or store and distribute video 
material.
BD-RE
BD-RE (Blu-ray Disc Rewritable) is a 
recordable and rewritable Blu-ray Disc, 
available in the same capacities as the BD 
below. The re-recordable feature makes 
extensive editing and time-shifting applications 
possible.
BD-ROM
BD-ROMs (Blu-ray Disc Read-Only Memory) 
are commercially produced discs and are 
available in the same capacities as the BD 
below. Other than conventional movie and video 
contents, these discs have enhanced features 
such as interactive content, menu operations 
using pop-up menus, selection of subtitle 
display, and slideshow. Although a BD-ROM 
may contain any form of data, most BD-ROM 
discs will contain movies in High Definition 
format, for playback on Blu-ray Disc/DVD 
players.
Blu-ray Disc (BD)
A disc format developed for recording/playing 
high-definition (HD) video (for HDTV, etc.), 
and for storing large amounts of data. A single 
layer Blu-ray Disc holds up to 25 GB, and a 
dual-layer Blu-ray Disc holds up to 50 GB of 
data.
Digital Cinema Auto Calibration 
(D.C.A.C)
Digital Cinema Auto Calibration was developed 
by Sony to automatically measure and adjust the 
speaker settings to your listening environment in 
a short period of time. 
Dolby Digital
This movie theater sound format is more 
advanced than Dolby Surround Pro Logic. In 
this format, the surround speakers output stereo 
sound with an expanded frequency range, and a 
subwoofer channel for deep bass is 
independently provided. This format is also 
called “5.1” with the subwoofer channel 
designed as the 0.1 channel (since it functions 
only when a deep bass effect is needed). All six 
channels in this format are recorded separately 
for superior channel separation. Furthermore, 
since all the signals are processed digitally, less 
signal degradation occurs.
Dolby Digital Plus
Developed as an extension to Dolby Digital, the 
audio coding technology supports 7.1 multi-
channel surround sound.
