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.
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.
Dolby TrueHD
Dolby TrueHD is a lossless coding technology
that supports up to 8 channels of multi-channel
surround sound for the next generation optical
discs. The reproduced sound is true to the
original source bit-for-bit.
DTS
Digital audio compression technology
developed by DTS, Inc. This technology
conforms to 5.1-channel surround. This format
comprises of stereo rear channel and there is
discrete subwoofer channel in this format. DTS
provides the same 5.1 discrete channels of high
quality digital audio. The good channel
separation is realized due to the all channel data
being recorded discretely and processed in
digitally.
DTS-HD High Resolution Audio
Developed as an extension to DTS Digital
Surround format. It supports a maximum
sampling frequency of 96 kHz, and 7.1 multi-
channel surround.
DTS-HD High Resolution Audio has a
maximum transmission rate of 6 Mbps, with
lossy compression (Lossy).
DTS-HD Master Audio
DTS-HD Master Audio has a maximum
transmission rate of 24.5 Mbps, and uses
lossless compression (Lossless), and DTS-HD
Master Audio corresponds to a maximum
sampling frequency of 192 kHz, and maximum
of 7.1ch.
HDMI (High-Definition Multimedia
Interface)
HDMI is an interface that supports both video
and audio on a single digital connection,
allowing you to enjoy high quality digital
picture and sound. The HDMI specification
supports HDCP (High-bandwidth Digital
Content Protection), a copy protection
technology that incorporates coding technology
for digital video signals.
Interlace format
(Interlaced scanning)
The Interlace format is the NTSC standard
method for displaying TV images at 30 frames
per second. Each frame is scanned twice -
alternately between the even numbered scanning
lines and then odd numbered scanning lines, at
60 times per second.
LTH (Low to High)
LTH is a recording system that supports organic
pigment type BD-R.
