Does Wireless Home Cinema C REALLY Work in 2017?

Does Wireless Home Cinema Projection REALLY Work in 2017?

It’s a truth universally (if reluctantly) acknowledged that for the most part wireless technology still isn’t all that reliable. But with more and more tech in our lives, the demand for great wireless solutions is growing – if only to avoid transforming our living rooms into a sea of wires.

If you’re among those on a quest to set up a wireless home cinema projector as part of this wire cleanse, then read on. We’ve put together a few tips on how to get the most out of a wireless setup along with our guide to the best wireless projectors on the market.

The Projector

First up, the star of the show: the projector. We know as well as anyone that wireless projectors don’t have a great reputation when it comes to holding a signal and delivering the high quality visuals we demand from our devices these days. However, the experts at Projectorpoint had a welcome surprise when testing the latest projectors from Epson.

The company’s new home cinema projectors, the EH-TW6700W and the EH-TW9300W, really impressed us with results that equalled those of their wired counterparts. So much so, in fact, that even us tech buffs struggled to tell the wired and wireless video apart.

Epson’s Home Cinema Heroes

Already in high demand, the Epson EH-TW6700W offers flexible projector placement combined with a wireless HDMI transmitter to created versatile home cinema streaming and video playback anywhere in the home. Practically indistinguishable from its wired counterpart, the device delivers flawless video at the touch of a button for the ultimate home cinema experience.

If high definition isn’t quite enough for you then how about the EH-TW9300W? Capable of delivering enhanced 4K UHD resolution video via a wireless transmitter, this clever device can connect wirelessly to up to four HDMI sources.

Is an LED VIDEO WALL in your Church’s Future?

videowall

Video walls are rapidly becoming an essential part of church lighting designs. This has created exciting new opportunities to enhance your worship services, but it’s also raised questions about how to choose the video products that are right for your church. Things like pixel pitch, viewing distance, panel/module dimensions, and NITS are all important factors in selecting products for your video wall, but if you aren’t experienced they can leave you more than a little confused and cause you to spend more money than necessary by buying “more video panel” than your church actually needs.

The first thing to look at when evaluating a video panel for your church is pixel pitch. Pixel pitch is the center-to-center spacing between each LED (both vertical and horizontal), measured in millimeters. The smaller the pixel pitch, the closer your minimum viewing distance becomes. If you’re too close to a video panel based on its minimum viewing distance, the images will look pixelated; which means you’ll see the individual LEDs that make up the image rather than the image as a whole. So, if you want your video panels to convey images that look clear to worshipers, you have to make sure that the pixel pitch is appropriate for the distance between those panels and the first row in your church.

Here’s a simple formula to use when evaluating pixel pitches: allow one meter of viewing distance for every millimeter of pixel pitch. So, if your pixel pitch is 5.2 millimeters, your optimal/minimum viewing distance is 5.2 meters, which is approximately 15 feet.

Too often, we’ve seen churches “over-buy” pixel pitch when selecting video panels. For example, if the closest member of your congregation sits 50 feet from your video wall, you can buy a video panel with a 15 millimeter pixel pitch instead of a 5 millimeter pitch. (Panels with smaller pixel pitches cost more.) I compare what some churches do when over-buying pixel pitch to someone using a tractor trailer to haul a bag of groceries from the supermarket every week; it isn’t necessary or cost-efficient. Buying the pixel pitch that matches your needs (and nothing more) is the surest way to save money on video panels.

The next biggest thing to consider is the brightness of a video panel, which is measured in NITS. A NIT is a unit of measurement, defined as the cd/m2. It’s used primarily in televisions, projectors, and video walls. If you’re doing an outdoor event that takes place during the day, then you’re going to need to compete with the brightness of the sun. In this setting, you’re going to want to have a rating greater than 4000 NITS; otherwise, your content won’t be legible on the screen.

LED Is Almost Perfect

how-future-0712Perhaps no other technology is as poised to be used in more churches than LED. Seemingly the perfect balance of functionality, size, cost of operation and product lifespan, LED is almost perfect for the house of worship market.

LED Is Everywhere

Once reserved for those in the rarified atmosphere of near-unlimited budgets, LED technology has been embraced by all sides of the A/V/L industry. From audio consoles to video screens to lighting fixtures, LED is everywhere — and is making huge gains in terms of affordability and lifetime performance. It’s hard to look at any other singular technology, save for the microprocessor, that has made such a lasting impact on our industry and the applications and venues of end-users.

Similar to the secular venues, churches had been few and far between that were able to afford the high six-figure and seven-figure video LED video walls or even the high-brightness, long-throw LED production lighting fixtures. That’s changed — and continues to change rapidly — to bring both the availability and variety of LED technologies down in price for a much wider market adoption.

The case can now be made that the lifetime cost of LED lighting fixtures is lower than the cost of Tungsten-based fixtures, based on lamp changes and maintenance costs alone. Similarly, the options for LED video walls has also seen a dramatic shift, offering more churches to consider this over projection in certain venues — especially where natural light is a major consideration.

LED and LEED

The LEED certification process is white hot, with manufacturers and contractors alike looking to maximize their offerings to meet the green/energy efficient/sustainable definitions. The house of worship market, in particular, is impacted greatly in cities where LEED is becoming the norm as cities look to make venues less impactful on their environment and have a much smaller total power usage footprint. The cost benefits of LED fit perfectly into these scenarios due to the incredibly small amounts of power required and the zero-heat emissions.

Cost-benefit studies are being conducted by consultants, contractors and architects looking to make LED the new standard fixture — much less the production fixtures — for lighting venues. The bonus from an A/V/L side is the sudden ability to create nearly unlimited color mixing options for even architectural lighting is having a dramatic impact on the design and interior decorating of these new or updated church facilities.

LED — The Future of Lighting?

It is possible that LED fixtures will be the dominate light type for both architectural applications and production venues in the church market. And it might be happening within the very near future.

Of particular interest to churches is the fact that color mixing these lighting fixtures opens up an entirely new canvas — every surface. The latest LED lighting technology looks better the more you add color and high saturation levels — something that is very hard to do with a massive amount of Tungsten or arc-lamp lighting fixtures.

Today, LED lighting has a rightful place on the design drawings as architectural fixtures (indoor and outdoor), large space lighting, and mood/effect lighting on walls and ceilings. The technology isn’t quite perfected when it comes to long-distance front lighting, however, and doesn’t offer the color rendering of an old-fashioned Tungsten Leiko or Source Four — especially when seen through the lens of video cameras. Still, it’s a matter of time as we continue to see clever advancements in multiple “white” color temperature blending options to try to achieve the effect of Tungsten.

LED — The Future of Video?

From LED back-lit flat panels to full-blown LED video walls, this technology continues to push hard against physics and push open the door of opportunity for greater adoption in the video world. In some instances, LED video walls are actually more cost effective than extreme brightness projection. And, because larger church venues put the screen at sufficient distances to the closest viewer (and beyond), coupled with the incredible reduction of dot pitch/pixel pitch, LED may end up being the outright replacement of nearly all extreme brightness, large format projectors within the next five years.

As exciting as seven-color LED has been, it’s not inconceivable that even higher count LED solutions (likely incorporating multiple color temperatures of “white”) will come on the scene to bring life-like quality to match the increased resolution of 4K (and beyond) image capture devices.

XGA or WXGA

XGA or WXGAphoto credit:triplewidemedia.com

Wide resolution screens have made its way into becoming the preferred choice for monitor manufacturers. Most if not all current laptop and PC monitors are in wide format, commonly known as WXGA or 16:10. Some has even gone on to HD format, 16:9.

Similarly for large screen industry, we are seeing an increase number of WXGA format projectors but demand for the old XGA or 4:3 resolution projector is still strong despite the market shift, why?

To help users better understand the difference, the following comparison table should give a good idea on the pros and cons between the XGA and WXGA format projectors:

Performance XGA, 1024 x 768 pixels (4:3) WXGA, 1280 x 800 pixels (16:10)
Image quality If the image is generated from a WXGA format source, it will be ‘force down’ to fit as XGA format. Hence the projection will look elongated vertically and sharpness will be affected. Some projector may support 16:10 without distortion of the image, instead, the projector will block off a certain amount of pixels to make the image resolution match that of a 16:10 ratio. This method will actually deprive users on maximizing the pixel available on the projector and image quality will too be compromised. WXGA native resolution projectors will have an option to go down to XGA, hence a change of settings will help ‘sync’ the projector screen to match nicely with your older version PC/ laptop monitors.
Image Size Despite having fewer pixels than a WXGA format projector, it will have a larger image when projecting side-by-side with a WXGA projector on a screen with the same width. This is due to the advantage from the 4:3 ratio, giving more height to the entire image. Despite a larger screen size, its image sharpness will not be comparable to WXGA. Disadvantage of a wide format image is the wastage of projection space. Image size is confined to the limitation of its width. If there is insufficient width for projection, a WXGA image will look a lot smaller than that of a 4:3.
Cost Generally XGA projectors will cost $200 – $400 cheaper than a similar specification WXGA projector WXGA having more pixels uses a ‘larger’ chip hence a heftier price tag.

It really boils down to the individual requirements of each user to get the right resolution projector to better suit his/ her budget. The following points should help you look out for the right consideration when deciding between XGA or WXGA.

1. Type of image source

Are you buying the projector for purely presentation or playing video? Is your existing source (i.e. Laptop, DVD Player, Cable TV Setup Box) for 4:3 or 16:10/ 16:9?

2. Size of image

How big (width and Height) are you prepared to project up to?

3. Budget

How much are you willing to spend? (not forgetting cost incurred on installation)
