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
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.
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.
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.
