Glossary

Interlaced

A method of image scanning whereby the signal bandwidth used is approximately half

scanning

that required for sequential scanning when images with the same still picture

 

resolution are broadcast.

 

 

Refresh Rate

The light-emitting element of a display maintains the same luminosity and color for an

 

extremely short time. Because of this, the image must be scanned many times per

 

second in order to refresh the light emitting element. The number of refresh operations

 

per second is called the "refresh rate", and is expressed in hertz (Hz).

 

 

Remote

Connects an optional remote control receiver.

port

 

S-Video images

A video signal which has the luminance component and color component separated in order to provide better image quality.

It refers to images which consist of two independent signals: Y (luminance signal), and C (color signal).

SDTV

An abbreviation for Standard Definition Television. It refers to standard television

 

systems which do not satisfy the conditions for High-Definition Television.

 

 

Security lock

A device consisting of a protector case with a hole in it that a commercially-available

 

theft-prevention cable can be passed through in order to secure the device to a table or

 

pillar. This projector is compatible with the Microsaver Security System manufactured

 

by Kensington.

 

 

Source prompt

The screen display showing the type of signal being input.

 

 

sRGB

An international standard for color intervals that was formulated so that colors which

 

are reproduced by video equipment can be handled easily by computer operating

 

systems (OS) and the Internet.

 

 

SVGA

A type of video signal with a resolution of 800 (horizontal) x 600 (vertical) dots which

 

is used by IBM PC/AT-compatible computers (DOS/V computers).

 

 

SXGA

A type of video signal with a resolution of 1,280 (horizontal) x 1,024 (vertical) dots

 

which is used by IBM PC/AT-compatible computers (DOS/V computers).

 

 

Synchronization

The signals output from computers have a specific frequency. If the projector

(Sync.)

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 "synchronization". If the signals are not

 

synchronized, problems such as flickering, blurriness and horizontal interference can

 

occur.

 

 

Tracking

The signals output from computers 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.

 

 

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 1,600 (horizontal) x 1,200 (vertical) dots

 

which is used by IBM PC/AT-compatible computers (DOS/V computers).

 

 

VGA

A type of video signal with a resolution of 640 (horizontal) x 480 (vertical) dots which

 

is used by IBM PC/AT-compatible computers (DOS/V computers).

 

 

XGA

A type of video signal with a resolution of 1,024 (horizontal) x 768 (vertical) dots

 

which is used by IBM PC/AT-compatible computers (DOS/V computers).

 

 

YCbCr

The carrier signal which is contained in the color bar signal used in modern TV

 

transmissions (NTSC format). The name comes from the Y (luminance) signal and the

 

CbCr (chroma [color]) signals.

 

 

YPbPr

The carrier signal which is contained in the color bar signal used in high-definition TV

 

(HDTV) transmissions. The name comes from the Y (luminance) signal and the PbPr

 

(color difference) signals.
