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 WPAg. 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 addressg 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.
