Film judgment function

Gateway
A server (router) that is used for communication over a network (subnet) that is divided up using subnet masks.
HDTV

•Vertical resolution of 750p or 1125i or greater (p =
scanning)
of 16:9
•
audio reception and playback (or output)
Interlaced
A method of image scanning whereby the image data is divided into fine horizontal lines which are displayed in sequence
starting from left to right and then from the top to the bottom of the screen. The even-numbered lines and odd-numbered lines
are displayed alternately.
IP address
A series of numbers that identifies a device that is connected to a network.
MAC address
Abbreviation for Media Access Control address. A MAC address is a unique ID number that is assigned to each network
adapter. All network adapters are assigned this unique address, and these are used as the basis for communication between
each network adapter.
Progressive
A method of image scanning whereby the image data from a single image is scanned sequentially from top to bottom to create
a single image.
Refresh rate
The light-emitting element of a display maintains the same luminosity and colour 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).
Resize display
This function is used to project computer images that have a resolution more than or less than the projector's panel resolution
to be projected so that they fill the whole of the projection area.
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 projector 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.
SNMP
Abbreviation for Simple Network Management Protocol. In TCP/IP networks, this protocol is used for communication
between routers and other devices that are connected to the network such as computers and terminals so that these devices can
be monitored and controlled over 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.
