Progressive Projects information to create one screen at a time, displaying

the image for one frame.

Even though the number of scan lines is the same, the amount

of flicker in images decreases because the volume of

information has doubled compared with an interlace system.

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 to refresh the light-emitting element.

The number of refresh operations per second is called the

Refresh rate and is expressed in hertz (Hz).

SDTV An abbreviation for Standard Definition Television that refers

to standard television systems which do not satisfy the

conditions for HDTV High-Definition Television.

SNMP An abbreviation for Simple Network Management Protocol,

which is the protocol for monitoring and controlling devices

such as routers and computers connected to a TCP/IP network.

sRGB An international standard for color intervals that was

formulated so that colors that are reproduced by video

equipment can be handled easily by computer operating

systems (OS) and the Internet. If the connected source has an

sRGB mode, set both the projector and the connected signal

source to sRGB.

SSID SSID is identification data for connecting to another device on

a wireless LAN. Wireless communication is possible between

devices with the same SSID.

Subnet Mask This is a numerical value that defines the number of bits used

for the network address on a divided network (subnet) from the

IP address.

SVGA A screen size standard with a resolution of 800 (horizontal) ×

600 (vertical) dots.

SXGA A screen size standard with a resolution of 1,280 (horizontal) ×

1,024 (vertical) dots.

Sync. The signals output from computers have a specific frequency.

If the projector frequency does not match this frequency, the

resulting images are not of a good quality.

The process of matching the phases of these signals (the relative

position of the crests and the troughs in the signal) is called

Synchronization.

If the signals are not synchronized, flickering, blurriness, and

horizontal interference occur.

Tracking The signals output from computers have a specific frequency.

If the projector frequency does not match this frequency, the

resulting images are not 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

appear in the signal.

Trap IP Address This is the IP address for the destination computer used for

error notification in SNMP.

VGA A screen size standard with a resolution of 640 (horizontal) ×

480 (vertical) dots.

XGA A screen size standard with a resolution of 1,024 (horizontal) ×

768 (vertical) dots.

WXGA A screen size standard with a resolution of 1,280 (horizontal) ×

800 (vertical) dots.

WUXGA A screen size standard with a resolution of 1,920 (horizontal) ×

1,200 (vertical) dots.
