❖ 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, 1080i).
❖ 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.
❖ Multi-session
Multi-session/multi-border recording is a method of
recording two or more sessions/borders on a single disc.
When recording data on a disc, the unit comprising the
data from the beginning to the end of that instance of
recording is called a session or border.
❖ Parental Lock
See page 45.
❖ 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 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.
❖ x.v.Color
