Dolby Digital Plus
Dolby Digital Plus is an audio format for high-definition media.
Built on Dolby Digital, it combines the efficiency and flexibility to
provide high quality multi-channel audio. With BD-ROMs, up to
7.1 channels of digital sound can be recorded.
Dolby TrueHD
Dolby TrueHD is an audio format using lossless coding. With BD-
ROMs, up to 8 channels can be recorded at 96 kHz/24 bits, or up
to 6 channels at 192 kHz/24 bits.
DRM
A technology for protecting copyrighted digital data. Digitized
videos, images and audio retain the same quality even when they
are copied or transferred repeatedly. DRM is a technology for
restricting the distribution or playback of such digital data
without the authorization of the copyright holder.
DTS Digital Surround
DTS Digital Surround is an audio format to record 48 kHz/24 bits
audio signals in 5.1 channels.
DTS-HD High Resolution Audio
DTS-HD High Resolution Audio is an audio format using lossy
coding. It can record 7.1 channels at 96 kHz/24 bits.
DTS-HD Master Audio
DTS-HD Master Audio is an audio format using lossless coding.
With BD-ROMs, 7.1 channels can be recorded at 96 kHz/24 bits,
or 5.1 channels at 192 kHz/24 bits.
Ethernet
A standard for local area networks (LANs) used to connect
multiple computers, etc. in the same location. This player
supports 100BASE-TX.
Frames and fields
A frame is the unit for one of the still pictures which compose
motion pictures. One frame consists of a picture of odd lines and
a picture of even lines called fields in video signal with interlaced
scan method (576i, 1080i, etc.).
HDMI (High-Definition Multimedia
Interface)
See About HDMI on page 13.
Interactive audio
The audio signals recorded in the titles of BD-ROMs. They include
for example the clicking sound made when the menu screen is
operated.
Interlaced scan
With this method, one picture is displayed by scanning it twice.
The odd lines are displayed in the first pass, the even lines are
displayed in the second, to form a single picture (frame).
Interlaced scan is indicated in this player and operating
instructions by an “i” after the resolution value (for example, 576i).
IP address
An address that identifies a computer or other device connected
to the Internet or local area network. It is represented a number
in four sections.
Linear PCM
This is referred as the audio signals that are not compressed.
MAC (Media Access Control) address
A hardware identification number assigned specifically to the
network device (LAN card, etc.).
MPEG (Moving Picture Experts Group)
The name of a family of standards used to encode video and
audio signals in a digital compressed format. The video encoding
standards include MPEG-1 Video, MPEG-2 Video, MPEG-4 Visual,
MPEG-4 AVC, etc. The audio encoding standards include MPEG-
1 Audio, MPEG-2 Audio, MPEG-2 AAC, etc.
Parental Lock
See Changing the Parental Lock level for viewing DVDs and
Changing the Age Restriction for viewing BD-ROMs on page 43.
Picture-in-Picture (P-in-P)
This is a function for superimposing a sub video on the main
video. Some BD-ROMs include secondary video, which can be
superimposed on the primary video.
Port number
This is a sub-address provided below the IP address for
simultaneously connecting to multiple parties during Internet
communications.
Progressive scan
With this method, one picture is consisted of a single picture,
without dividing it in two pictures. Progressive scan provides
clear pictures with no flicker, in particular for still pictures that
contain much text, graphics, or horizontal lines. Progressive scan
is indicated in this player and operating instructions by a “p” after
the resolution value (for example, 576p).
Proxy server
This is a relay server for ensuring fast access and safe
communications when connecting to the Internet from an
internal network.
Region number
See About region numbers on page 9.
Secondary audio
Some BD-ROMs include sub audio streams mixed with the main
audio stream. These sub audio streams are called “secondary
audio”. On some discs this secondary audio is recorded as the
audio for the secondary video.
Secondary video
Some BD-ROMs include sub videos superimposed on the main
videos using the Picture-in-Picture function. These sub videos are
called “secondary video”.
Subnet mask
This is used to identify which part of the IP address corresponds
to the subnet (a separately managed network). The subnet mask
is expressed as ‘255.255.255.0’.
USB(Universal Serial Bus)
USB is the industry standard for connecting peripherals to PCs.
VC-1
A video codec developed by Microsoft and standardized by the
Society of Motion Picture and Television Engineers (SMPTE).
Some BDs include videos encoded in this codec.
