HDMI
An abbreviated form of “High-Definition Multimedia
Interface”, which is the digital transmission standard for

transmission without signal compression. It also has a digital
signal encryption function.
HDTV

be applied to a high-definition TV set that can satisfy the
following requirements:
- Vertical resolution 720p or 1080i or higher (where, “p” refers

- 16:9 screen aspect ratio
JPEG
A file format used for saving image files. Most photographs
taken with digital cameras are saved in the JPEG format.

The abbreviated form of “MPEG1 Audio Layer-3”, a standard
for audio compression. It enables the size of the data to be
greatly reduced, whilst maintaining a high sound quality.

wave transmission systems. This system is used in Japan, the
USA and Latin America.

compression technology developed by the Microsoft
Corporation of America. You can encode WMA data using
Windows Media Player Ver.7, 7.1, Windows Media Player for
Windows XP, or the Windows Media Player 9 Series.
When encoding WMA files, please use applications that have
been certified by the Microsoft Corporation of America. If you
use an application that has not been certified, it is possible that
it may not operate correctly.
Aspect ratio
The ratio between an image’s length and its height. HDTV
images have an aspect ratio of 16:9 and appear elongated. The
aspect ratio for standard images is 4:3. This unit can
automatically detect the aspect ratio of a disc when it is played
back.
Cool-down
A process to enable the lamp to cool down from the high
temperatures attained during projection. This is performed
automatically when is pressed to stop the projection of
the image, or is pressed to turn the unit off. Do not unplug
the power cable during cool-down. If cool-down is not
performed correctly, the lamp or internal structure of the main
unit can overheat which may reduce the lifespan of the lamp or
cause damage to this unit. Cool-down is complete once the
main unit beeps twice.
Optical digital output
Converts the audio signal into a digital signal and enables it to
be transmitted along optical fiber. An advantage is that
interference is not produced, unlike conventional means, where
external interference is picked up by the cable.
Playback control (PBC)

screen or information you want to see from the menu screen
displayed.
