SNMP
This is an abbreviation of Simple Network Management Protocol. It is a protocol in a TCP/IP network for monitoring and
controlling communication devices on the network, such as routers, computers, and terminals across the network.
Squeeze mode
In this mode, wide-screen images in 16:9 mode are compressed in the horizontal direction so that they are stored on the
recording medium as 4:3 images.
When these images are played back by the projector in squeeze mode, they are restored to their original 16:9 format.
sRGB
An international standard for colour intervals that was formulated so that colours which are reproduced by video equipment
can be handled easily by computer operating systems (OS) and the Internet.
Subnet mask
This is a number which defines, from the IP address, the number of bits used in network addresses of assigned networks
(subnets).
SVGA
A type of video signal with a resolution of 800 (horizontal)
×
600 (vertical) dots which is used by IBM PC/AT-compatible computers.
S-Video
A video signal which has the luminance component and colour component separated in order to provide better image quality.
It refers to images which consist of two independent signals: Y (luminance signal), and C (colour signal).
SXGA
A type of video signal with a resolution of 1280 (horizontal)
×
1024 (vertical) dots which is used by IBM PC/AT-compatible
computers.
Sync (synchronisation)
The signals output from computers and RGB video equipment have a specific frequency. If the projector frequency does not
match this frequency, the resulting images will not be of a good quality. The process of matching the phases of these signals
(the relative position of the crests and troughs in the signal) is called "synchronisation". If the signals are not synchronized,
problems such as flickering, blurriness and horizontal interference can occur.
TKIP
Abbreviation for Temporal Key Integrity Protocol. This is an encoding method used for
WPA
g
. The encryption key is
renewed after a certain period of time to make it harder to break the encryption code.
Tracking
The signals output from computers and RGB video equipment have a specific frequency. If the projector frequency does not
match this frequency, the resulting images will not be of a good quality. The process of matching the frequency of these
signals (the number of crests in the signal) is called "tracking". If tracking is not carried out correctly, wide vertical stripes will
appear in the projected images.
Trap IP address
This is the
IP address
g
of the messaged computer used for error notification in SNMP.
USB
An abbreviation for Universal Serial Bus. USB is an interface for connecting personal computers to peripheral devices which
only support relatively low data transmission speeds.
UXGA
A type of video signal with a resolution of 1600 (horizontal)
×
1200 (vertical) dots which is used by IBM PC/AT-compatible
computers.
VGA
A type of video signal with a resolution of 640 (horizontal)
×
480 (vertical) dots which is used by IBM PC/AT-compatible
computers.
WEP
This is an abbreviation of Wired Equivalent Privacy. This is a security method which encrypts data during transmission.
Data communication cannot be performed unless the sending and receiving machines are registered with the same encryption
key by the WEP.
