A. To Explain What Multimedia Projector is?
Multimedia
projectors are used frequently in classrooms, offices and gatherings at which
multimedia presentations are made. In a film class, for example, the teacher
can integrate select video sequences into a slide show of note pages. In a
marketing meeting, a presenter could alternate seamlessly between spreadsheets,
animated ad content and live feeds from social media sites.
A multimedia projector is a compact,
high resolution, full-color projector capable of projecting text, images, video
and audio content. Typically the projector will feature inputs for a computer, DVD player, VCR, CD player and
storage device.
Because people learn information in
different ways, modern presentations in classrooms and businesses often use a
variety of methods, including moving pictures and sound. Multimedia projectors
are utilized in such presentations as well as for home theater use.
Uses
Using a multimedia projector, you can
show a DVD, video, slide show or television program on a large screen with
color and sound. Multimedia projectors allow for presentations that can be used
for work functions, classroom instruction or enjoyment of films and television
at home.
Function
Multimedia projectors can be
connected to computers, VCRs, DVD players and cable boxes. The images
transmitted from the device are then transmitted into a special digitized light
that is reflected on thousands of mirrors within the projector, which shines
the image onto a screen.
Synonyms
Multimedia projectors are also
referred to as data projectors, digital projectors and data/video projectors.
These names can apply to both portable and ceiling-mounted units provided that
they can project computer output.
Types
Ultralight multimedia projectors
weigh less than 3 lb. and are ideal for people who frequently use projectors
for presentations on the road. Conference room projectors are heavier and
brighter, making them better suited to large rooms. Fixed multimedia projectors
used in auditoriums or in high-quality home theater setups weight over 100 lb.
and have the clearest and brightest pictures.
Features
Some multimedia projectors are
equipped with remote controls, making them easy to use from any point in a
room. Multimedia projectors may also be designed to handle types of formats
used to prevent media piracy throughout the world, which allows them to play
any type of movie, including those encoded with NTSC, SECAM and PAL formats.
They also might include memory capabilities that allow them to project
computer-based presentations without being connected to a computer.
