Is
the Mainstream Ready for Wireless?
As projector manufacturers incorporated wireless networking into their projectors, is it something that end-users will actually use?
By Tim Cape, CTS-D
I’m a geek. I admit it. I like
gadgets and get excited about
electronic doodads that non-geeks just can’t appreciate. As a result,
I’ll try
something out and have fun with it for a while, but only the truly
useful things
stick with me—my PDA, for example. It’s long outlasted its initial
thrill as a
geek toy to become a indispensable tool.
But some things just fall by the
wayside after the newness
wears off. Take wireless networked projectors for instance, and in
particular,
the on-board presentation capabilities that come with them.
First some background: A few years
ago when LCD projectors
burst onto the market, CRTs became passé almost immediately for many.
Selection
of a non-CRT projector wasn’t easy, though.
There were vast differences is
display quality between
manufacturers and models, especially when it came to NTSC video. This
is what
made the Projector Shootout at Infocomm such an attraction.
Not so today. Brightness is up, video
quality is up,
resolution is up, everything is looking up, and the differences between
the
projectors are less than ever before.
In many cases, what has become more
important for selecting
projectors—and many other pieces of AV equipment—for an integrated
project is
the feature set. Not just the complement of inputs, but the non-video
part:
controllability, networking capability, the look of the case, the noise
output,
the on-board computing.
After a good picture, the most
important feature I look for
in a projector is the control capability. What can the projector do
besides
project? Are there discrete RS-232 commands? Is
there IP capability? Can we use both ports
at the same time? Is lamp life readily available without having to know
the
secret handshake?
Is there on-board picture-in-picture?
Is there email
capability? These are the things that differentiate projectors these
days for
an integrated application.
Then there’s the on-board computing.
The concept of putting
the presentation capability on the projector certainly seems attractive.
No need for the computer. No need for
a video cable. No need
for a wireless mouse for the computer—just use the projector’s remote.
Besides, all the technology is there
to provide these
capabilities, so why not do it, right?
I have tried out a few of these
projectors with the
manufacturer’s help and once it’s working, it’s cool. But even without
any
glitches, the setup and infrastructure required for these types of
devices to
work takes some dedication even for us geeks.
Can we expect the average presenter
to embrace this effort?
A presenter or instructor wants a tool, not a project, to be able to
display
their presentation.
We see and hear that many people seek
demos of this
technology, but no one is using it. Is it ahead of its time, or just
too hard?
I believe that it’s a matter of
perceived simplicity vs.
real simplicity.
It seems that getting a presentation
to a projector from a
computer would be simpler without RGBHV cables, or even without cables
at all.
But it turns out that it’s more like
trying to swim across a
river when the bridge across it is right next to you. It would be a lot
easier
to stay out of the water for now.
Like many aspects of our business,
this is another
transitional growing pain. The idea of a laptop that’s also a projector
may not
be far off, but today’s offerings don’t have quite enough power to do
more than
standard PowerPoint at 8-bit color, and there are few, if any, that are
upgradeable.
It’s possible to playback video files
on these systems, too,
but the performance doesn’t hack it. And if you want to upgrade the
projector’s
built-in computer, you’ll have to buy a new projector.
The projector features that are
really differentiators for
me are the control features, not the computer or even wireless
networking.
But all the manufacturers feel a need
to offer these options
because a few have.
I’d rather see more options in
modularity like separate
lenses, light engines and input modules so you don’t need a whole new
projector
to get a new feature or accommodate a new input standard or additional
sources.
How about an installation-grade native 16:9 projector?
Don’t get me wrong. I’m not a Luddite
by a long shot.
It’s just that computing on a
projector has a long way to go
before more than the geekiest of presenters will be using this feature
with
regularity or before it becomes useful for installed systems.
One day this concept will be viable.
For now though, it’s
the control, management and diagnostic abilities that a processor
brings to the
projector that keep me interested, not the ability to present the hard
way,
wirelessly or not.
