size to fit the size of the screen of video equipments
such as a TV.
DVD video (pages 9, 26)
A disc format that contains up to eight hours of
moving pictures on a disc the same diameter as
a CD. A single-layer single sided DVD holds up to
4.7 GB; a double layer single-sided DVD, 8.5 GB; a
single layer double-sided DVD, 9.4 GB; double-layer
double-sided DVD, 17 GB. The MPEG 2 format was
adopted for efficient video data compression. It is
a variable rate technology that encodes the data to
according to the status of the video for reproducing
high-quality images. Audio information is recorded
in a multi-channel format such as Dolby Digital,
allowing for a realistic audio presence.
DVD+/-R (pages 9, 26)
A DVD+/-R is a recordable, write-once DVD.
Since contents can be recorded and cannot be
overwritten, a DVD+/-R can be used to archive data
or for storing and distributing video material. The
DVD+/-R has two different formats: VR format and
Video format. DVDs created in Video format have
the same format as a DVD video, while discs created
in VR (Video Recording) format allow the contents to
be programed or edited.
DVD+/-RW (pages 9, 26)
A DVD+/-RW is a recordable and rewritable DVD.
The re-recordable feature makes editing possible.
The DVD+/-RW has two different formats: VR format
and Video format. DVDs created in Video format
have the same format as a DVD video, while discs
created in VR (Video Recording) format allow the
contents to be programed or edited.
HDMI (page 16)
HDMI (High-Definition Multimedia Interface) is an
interface that supports both video and audio on
a single digital connection. The HDMI connection
carries standard to high definition video signals
and multi-channel audio signals to AV components
such as HDMI equipped TVs, in digital form without
degradation.
Infrastructure mode (page 20)

Linear PCM Sound
Linear PCM is a signal recording format used for
Audio CDs and on some DVD and Blu-ray discs. The
sound on Audio CDs is recorded at 44.1 kHz with
16 bits. (Sound is recorded between 48 kHz with 16
bits and 96 kHz with 24 bits on DVD video discs and
between 48 kHz with 16 bits and 192 kHz with 24
bits on BD video discs.)
MHL (Mobile High-definition Link) (page
43)
MHL is a mobile audio and video interface standard
for transmitting digital audio and high definition (HD)
video (1080p/30fps) without any compression.
MP3 (pages 9–11, 35, 37)
MP3 files are audio data compressed in the
MPEG1/2 Audio layer-3 file format. “MP3 files” have
“.mp3” as extensions.
MPEG-2
MPEG-2 (Moving Picture Experts Group phase 2) is
one of the video data compression schemes, which
is adopted for DVD videos and digital broadcasts
