Streaming into the Future: How bandwidth needs have expanded for Houses of Worship

by | Feb 28, 2023 | Uncategorized

Let us rewind the clock to early 2019. I was in a discussion with a customer who asked me what the top verticals were in regards to bandwidth needs. I had received this very common question countless times, so I answered in the same manner: hospitality, bar & restaurant, education, etc. As we happily fast-forward through 2020 and 2021, I would now place House of Worship amongst the top 3. The reason is quite simple — as the Hospitality and Bar/Restaurant markets clearly battled the ripple effects from the pandemic, it was Houses of Worship who I believe felt a similar impact that few were prepared for. Houses of Worship rely on the some of the same factors as those other verticals do, but the impact can be overlooked if you are not able to predict the future. To survive, these places of worship must keep their doors open for the community and be able to spread their message to the congregation. Shutter those doors due to a global pandemic, and the message risks getting lost.

It was quite fitting that in February 2020, less than 30 days from the time that the state of NJ shut down, I found myself attending a project walk-through at Groveville United Methodist Church in Groveville, NJ. The purpose of this visit was to update the audio/visual and to use this new technology to attract new members in the future. One by one, the integrator and I ran through qualifying questions to better identify the needs they had as we assembled the perfect bill of materials. I asked the church’s technical director if he planned on streaming services or events, to which he immediately said, “We prefer to have folks here in person.” Having understandably not been able to predict what the future held, I certainly do not blame him or others for replying in that manner. As we fast-forwarded to April 2020, I remember a phone call with another integrator who seemed exasperated on the call as he explained, “I have this very small, rural church in Illinois, and they desperately need to be able to stream their services to reach their members at home.” This was the moment it became the clearest – Houses of Worship had a dire need to reach members near and far and to achieve that, Bandwidth was the top requirement.

Streaming used to be a “cool to have” rather than a “have to have” need in this space. Most would probably associate streaming to the Mega Churches that we see on TV or in major cities. However, much like how the Pro AV industry and the push to use AVoIP, HoW have grown to accept that streaming simply cannot be overlooked. The question becomes, “Where do we even begin?” I say, start at bandwidth! There are two types of bandwidth in play here: the bandwidth that you are streaming at and the bandwidth that the stream is being watched at. Let us address these in two separate ways. Bandwidth is provided with two numbers – a download speed and an upload speed. When I refer to something as a 100×10 that means 100mb download and 10mb upload. When we are discussing streaming needs, we pay closer attention to the “UP” number specifically, because you are uploading the stream of the video and sharing this content to a larger audience. A general rule of thumb is that you have no less than a stable 5mb (megabits) upload speed to successfully stream. Given how most high speed cable internet providers start at 10mb upload speeds nowadays, this should not be too difficult to achieve. With that being said, any internet customer needs to understand that just because you are paying for a 100×10 cable package, does not mean you are receiving consistent 100×10 speeds. Those numbers are simply the “maximum advertised speeds” that the provider promotes, but when you factor in things like network traffic, time of day, and other extenuating circumstances (think about the number of people working from home and homeschooling in 2020 as an example), the speeds you receive in real time will almost normally be less. It is because of this that I never would recommend the bare minimum. For typical streaming needs, I would be comfortable recommending a 300×20 package or higher. This should ensure that you never run into issues when you can least afford to! Thinking back to the small, rural church I mentioned earlier, they were relying on a local DSL connection, which only had upload speeds of 1.5mb, hence their dire need to improve.

The second type of bandwidth we need to be cognizant of is the bandwidth at which the video is being watched. Obviously, it is an impossible task to attempt to determine the bandwidths of everyone who is watching, so you might want to offer the stream in different forms: HD, 4K, etc. A good HD stream would fall under the 5mb recommendation I just made, whereas 4k would cause that to rise, but again, say 10-15mb most high speed cable options will suffice nowadays in regard to the content streaming. While talking about the content streaming, we cannot overlook other factors such as the overall number of devices on the customer’s network. Thinking about your own home as an easy example. You probably have cell phones, smart TVs, thermostats, alarm systems, tablets, PC’s and more all tied to your home network. If you now apply that same thought to HOW you may have some similarities such as cell phones, PC’s etc. but now you might also have streaming cameras, audio components, assistive listening devices and more to consider. It is because of this that many HOW will look to a Dedicated Internet Access (aka Fiber) because it is as the name implies. You are receiving a dedicated service for your building that is backed by an SLA (service level agreement) therefore; you are receiving the speeds you are paying for. It might be wiser to look at a 50×50 DIA service instead of that 300×20-cable service, based on what your needs are and what your network looks like. Sure there is an increase in cost with DIA, but the peace of mind you will receive each time you attempt to stream a service is worth it in most cases. Wouldn’t you agree?

Bandwidth within HOW is not a “one size fits all” model. I have already mentioned high-speed cable, DIA, and DSL as examples of what is out there. You also have wireless and satellite services, which in the right situation, could still be viable sources. What do you do when you are a small/rural church with no cable or fiber internet available within 100 miles? You possibly turn to a satellite internet service, which is available, nationwide and while not as adequate as a 10mb upload speed, can still offer 4mb, which for a small church should do the trick. The key is- options are available to nearly everyone! For houses of worship and integrators alike, there are more bandwidth options than ever before to help make streaming into the future a PRESENT reality.

Edition 3 of “This May Be a Dumb Question, but…”

by | Feb 21, 2023 | Professional Development, Projectors, Uncategorized

This Blog Series is written by Exertis Almo's Business Development Managers: 
Ashley Nichols, CTS, DSCE, and John Borns, CTS, DSCE.

Welcome back to the 3rd installment of “This may be a dumb question, but…” In Edition 2, we began exploring the vast world of projection and it’s many facets, but specifically, we went over the differences in Laser vs. Lamp projection, as well as the foundation for choosing the best projection screen, so if you want to start there, here is a link to Edition 2.

Since projection has so many layers to picking the right solution, we are going to continue drilling down. On to the questions!

QUESTION
What is the difference between all the different projector technologies? I see 3LCD, DLP, LCOS, Laser, Lamp, etc., and I don’t understand what the difference is and when to use them.

ANSWER

In every technology installation, it is important to know the full scope of what your client is trying to accomplish. Seems simple, but you would be surprised how often the details do not come with the request. It’s not just about if you can rattle off all the projector specs. What sort of experience do they want? Do they need color accuracy because they need the best possible picture? Are they just looking at random power points and are looking for a budget option? Is it in a setting where they need a very quiet projector? There are MANY more questions involved in this decision, which we will look into more in the next few editions, but the answers to some of these questions could narrow down or determine which ‘color source’ or ‘chipset technology’ you will go with once you have decided on the laser or lamp dilemma. Before we move on, I’d scoot down to the ‘Vocab Test’ and refresh your memory on the 3 main projector technologies we see today in the Pro AV space.

Alright, on to the cheat sheet. To break it down as simply as possible, we’ve created a brief guide below.

Note: this is not the most comprehensive list of Pros and Cons, and like everything else in AV, it is subject to interpretation and experiences, but this can help those little light bulbs go off in your head when your customer starts describing their upcoming projects:

TECHNOLOGY VERTICALS BEST SERVED PROS CONS LASER OR LAMP?
1 or 3 chip DLP1 -Education
-Corporate
-House of Worship
-Bars/Restaurants
-Museums
-Large Venues
-Cinema
-Simulators		 -Deep Blacks
-DLP uses mirrors to reflect light, so there is no degradation over time (aka longer lifespan)
-Minimal motion blur		 -Doesn’t appear as bright as LCD
-‘Rainbow effect’ due to the spinning wheel in 1-chip models		 Can be both
3LCD2 -Education
-Corporate
-House of Worship
-Bars/Restaurants
-Museums
-Large Venues		 -Most cost-effective up front
-Higher brightness for comparably priced models
-Most portable		 -LCD degrades overtime, causing brightness and picture degradation
-Motion blur can be an issue		 Can be both
LCoS3 -Corporate
-Cinema
-Simulators
-Museums		 -One of the best native contrast options
-Deep blacks
-Native 4k in most cases		 -Heavier and not as portable
-Like LCD, LCoS can have an issue with motion blur in fast scenes
-Expensive		 Can be both

In Edition 4, we will discuss the next step in our process once we determine lamp or laser, and which projector type (DLP, LCD, or LCoS) – which is determining placement of the projector, how bright we need it based on our room, and screen size. It will require some math, so bring your scratch paper. ✍️

QUESTION
I’ve noticed that sometimes projection screens aren’t always white. Sometimes they’re off-white, or gray. Why would that be?

ANSWER

I’ll answer your question by starting with a fun fact!The term “silver screen” was coined in 1920s when projection screen manufacturers and theater houses started using silver paint on screen surfaces. At the time they found that a silver screen made the images “pop” more, provided better contrast4 (very important in black and white films), and reduced blurriness and washing out of the images. This makes sense if you really think about how reflective the color white can be. If you’ve ever walked outside on a sunny day when the ground is covered in snow, you know how incredibly reflective and blinding pure white snow can be. Have you ever been blinded by the gray snow on the side of the road after the plows?

There’s really two advantages that come from using a screen that is gray instead of white. Firstly, by reducing the overall reflectiveness/reflectivity/reflection-factor of a screen, you can avoid the projected image from being blindingly bright (washout5). Well, in addition to combating washout, it can also help with ambient light issues. In the last issue, we covered how ambient light in the room can interfere with the projected light you actually want to see.

Another way combat that issue is by using a darker screen. The gray material will absorb the ambient light better and allow the desired light to shine (pun definitely intended) through. Additionally, just as in the 1920s, using a gray screen can help improve the quality of motion pictures. Technically speaking, projectors can’t project the color black. So, if you’re watching a dark action movie, like John Wick (which you totally should be, because it rules), then you’re going to want to be able see the action clearly and crisply. Having a darker screen will help the projector produce dark colors better, and allow for deeper contrast, which will help the action and figures stand out more clearly. Now, this isn’t to say that you should always use a gray screen, there are many situations in which a white screen will work just fine. surface-reflection-toolThe brightness of the projector, the projector technology being used (see previous question), the light in the room, the intended uses of the system, and the budget, are all key factors that you need to consider when building a projection system. The important thing is to make the right choice by evaluating all of the factors. There are many tools out there that can help you determine which screen surface is right for you. I personally like this one that our friends at Dalite have come out with 📽️ surface selection tool.   [click image to enlarge →]

Vocab Test Time!

Are these the most detailed definitions? No – we are not a dictionary, nor the AVIXA CTS Prep book. Will someone message us after still telling us how much we missed? Possibly. Will these get you a basic working knowledge of these terms and why they matter? We hope so. Plus, we are 99% sure they will help you impress your grandparents when you reset their WiFi.

  1. DLP – Stands for ‘Digital Light Processing,’ a type of chipset in display and projector technology that uses reflective surfaces/mirrors and color wheels to project light and color onto the screen.
  2. LCD or 3LCD – Stands for ‘Liquid Crystal Display,’ or ‘3 [Chipset] Liquid Crystal Display,’ which is a type of chipset that uses the white light from the source (lamp or laser) and reflects them through 3 light panels. The projector controls how much light passes through these panels to then create the image on the screen.
  3. LCoS – Stands for ‘Liquid Crystal on Silicon,’ which is a little bit of a mix between LCD and DLP technology. LCoS projectors use the mirrors of a DLP projector with the liquid crystal panels of an LCD to create bright, beautiful images, but without the ‘rainbow effect’ of DLP from the spinning color wheel.
  4. Contrast – A measurement/description of the differences between the white and black colors in a projected image.
  5. Washout – When the projected image is too bright or has too much white light is reflecting, detracting from the overall image quality.
  6. Wipeout– America’s Largest Obstacle course game show.

Navigating Changes During Business Consolidation

by | Feb 7, 2023 | Uncategorized

Navigating Change During Business Consolidation

One year following a prominent merger in the Pro AV industry, three industry veterans, Darren Altman, Business Development Manager at Exertis Almo, and Sharp/NEC‘s David Lacoff and Mark Weniger, discuss the changes and opportunities that arise when navigating business consolidation.

Maintaining Patience

While significant business changes often bring stress and nervousness among team members, Darren, Dave and Mark examine the role of patience in new situations, especially during a company merger.

“Thankfully, patience is a virtue,” said Darren. “I’ve never been on [the acquiree] side of an acquisition before – we were always the acquiring partner and being that [the news] was so new, I said, ‘Let’s just see what happens.’ It was interesting to see how management was staying and learning about the buying partner, and how they acquire companies that do things correctly, keep their personnel, invest in [the company] and keep it running smoothly.”

Dave details the busy months following the merger of the two prominent companies.

“I’ve been through this once before at a prior company, and we acquired another company and let them run the ship,” he explained. “From a personal perspective, here we are – as a vendor – going through a merger, trying to figure things out, and now two of our largest customers are doing the same – it’s gone by really quickly.”

The Value of Relationships

After the acquisition was announced publicly, Mark acknowledges the value and importance of each company’s business relationships, and the challenges that arise when two influential industry players merge their teams.

“It was really just business as usual, as the core leadership [mentality] was always to stay away from rumors,” explained Darren. “The last thing you want to do, regardless of the outcome of any joint venture or acquisition, is burn a bridge.”

While the acquisition marked the start of a new era for the newly combined groups, both teams ensured that all business relationships were properly maintained as changes occurred on each side.

“The relationships that our sales teams have made are more important than just having equipment in stock,” said Darren. While knowledge about product lines is imperative for business, Darren finds that the established relationships with customers, vendors, and manufacturers truly shine through, especially in the event of a large business change.

Identifying Expanded Opportunities, Increased Capabilities, and Room for Growth

Despite the challenges of two successful (and rival) companies merging, there are numerous opportunities for expansion and growth with an impact on the industry across the world.

“2023 will be the year that we’re all rowing in the same direction,” explained Darren. For decades, [our companies] have viewed each other as competitors in the distribution industry. With the combined financial resources and impressive supply-chain logistics on one side and a family-owned history and nationwide warehousing space on the other side, the acquisition paves the way for extraordinary accomplishments as one team.

Additionally, Mark explains the new possibilities regarding the combined product lines.

“You constantly get caught in a cycle of refresh after refresh, and you reach a point in the industry when there’s nothing really new – just updates,” he explained. “Having access to different projector lines, video wall SKUs, cost-effective collaborations – it’s a different area to pull product and knowledge from. I was excited because, as we’ve come to learn and have seen progress, the product lines made sense.”

Staying Thankful

While business acquisitions are admittedly high-stress processes, Darren discuss the importance of remaining thankful for the new business opportunities to come.

“Regardless of the role that you’re in, when acquisitions happen, there are always going to be bumps in the road,” explained Darren. “These changes take time, but once everything is ironed out, I don’t see why we can’t be one of the industry’s leaders, from the feet on the street to people behind their desks, in the manufacturing world and distributing world.”

By putting their trust in the newly combined leadership, Dave found that the merger resulted in new opportunities and increased with growth combined product lines, while maintaining the same, personal approach to everyday business.

“2023 should be a big year for all of us,” said Dave. We have an amazing opportunity in the market with our full product lines and team we have in place to really do well – I’m excited for the opportunity to continue to be a market leader and really affect the business in a positive way.”

Assistive Listening…Have You Heard the Latest?

by | Jan 19, 2023 | Pro Audio, Uncategorized

Most of us take hearing for granted these days. However, a large portion of the population in the U.S. (about 38% of those aged 12 or older) have some form of hearing loss. This equates to 1 in 8 people with some form of hearing loss. As a sound engineer who has relied on my ears for 30+ years working in the AV industry, I feel we need to take every step possible to assure those around us can hear as clearly as possible. There are more effective assistive listening technologies than ever before available today.

graph assistive listening

In the AV industry, we are in a unique position to promote products that can provide the hearing assistance needed by so many people. The choices range from loop systems to FM, IR, Bluetooth, digital, and Wi-Fi based systems, with the Wi-Fi systems gaining popularity as they allow the user to incorporate their own personal phone without need of an additional device. The ADA (Americans with Disabilities Act) also requires public spaces to provide ALS (Assistive Listening System) to accommodate those who require it.

Not only do we provide audio systems that can amplify all content to an audience, but we also have tools to help those with more acute hearing loss. Intelligibility is one of the leading issues that ALS can help to overcome. Sound systems provide overall sound level increases but to those with hearing loss, the intelligibility of the human voice can still be a problem.

ALS systems can also have other uses. Tour guide systems and Interpretation Systems also use this technology very effectively. Let’s explore the latest technology available and how it can be both a vital addition to any audio system, as well as profit center for the integrator. The most recent addition to ALS is the BYOD solution, such as ListenEVERYWHERE® by Listen Technologies. This system utilizes Wi-Fi technology for use with any user’s personal smart device or a proprietary smart device provided, should a user require it. By using their own device, the ALS can be seamless, flexible, and invisible. This is much more desirable than a solution that forces them to use a receiver for a proprietary system.

According to Sam Nord, VP of Global Channel Sales for Listen Technologies, “Listen Everywhere has broadened the ability of venues to offer assistive listening because it allows users to choose the method in which they want to be accommodated. For example, we’ve seen a huge interest in Wi-Fi based assistive listening technology in the education sector, where so many of the students are already smartphone users, so accessing assistive listening via their Smart device is often a preferred method compared to having to ask for a hardware device and the logistics that sometimes go along with that. Similarly, in the House of Worship market, Wi-Fi based assistive listening allows venues to offer assistive listening to a much larger portion of their congregations than a hardware based system since anyone with a smart device now has access to the system. That said, the availability of Wi-Fi receivers allows those patrons who prefer to use a separate device for assistive listening to be accommodated as well.”

This has addressed some of the hurdles that remain, regarding where ALS systems are required. There is still some confusion about this. The ADA requirements vary from state to state and for different venues as well. Education, performing arts, government, and most public spaces base their system requirements on the number of attendees or a ratio of the total seating capacities. Churches, in many cases, also provide ALS systems as a part of their ministry, even if they are not required. With the more conventional systems, the facility was required to purchase a system with a percentage of receivers that are made available to those who need them. This tends to draw attention to users, and in many cases, causes some to avoid getting the hearing assistance they really need.

“The more the AV industry understands about this technology and provides for their customers rather than just checking a box of being ADA compliant, the more widely ALS will be used,” Nord continues. “With assistive listening, to make sure we are accommodating those who need this important technology, the one thing I always evangelize is being proactive in pushing assistive listening rather than being reactive. If you are specifying speakers, microphones, or other audio technology into a project, there is a high probability that there are folks who will be utilizing that system who would benefit from an assistive listening system, so ensuring there is a system available is the best thing you can do to encourage inclusion.”

The main point here is that ALS should be considered a part of any audio system in a venue when the system is in the design phase, just like loudspeakers, amplifiers, or any other components. As the AV industry fully understands the benefit of the assistive listening systems, this will encourage inclusion for all who attend an event, go to church, and learn in a classroom.

church audio solutions

The next step is easy…Contact Exertis Almo and we can assist with any Assistive Listening Technology you may need for your project or facility. We can provide complete design support and connect you with companies like Listen Technologies to assure you have the best solution for any application. There are many new products on the horizon and 2023 will include some compelling upgrades to offer even further capability for this vital technology.

Edition 2 of “This May Be a Dumb Question, but…”

by | Jan 12, 2023 | Professional Development, Projectors, Uncategorized

This Blog Series is written by Exertis Almo's Business Development Managers: 
Ashley Nichols, CTS, DSCE, and John Borns, CTS, DSCE.

Welcome back to the 2nd edition of “This may be a dumb question, but…”, a now recurring blog series where two industry ‘veterans’ (or newbies, depending on who you talk to) help you find useful answers to the questions you’re too afraid to ask. Our 1st edition went over AV over IP, HDBaseT and RS-232, so follow this link if you want to learn more about those topics. This edition is all about Projection, so let’s get to the questions:

QUESTION
What is the difference between all of the different projector technologies? I see 3LCD, DLP, LCOS, Laser, Lamp, etc., and I don’t understand what the difference is and when to use them.

ANSWER

Hot Take: Projection is more complicated than your basic digital signage display. Yep, I said it. So many variables go into projection and choosing the right fit for your application, so it is no wonder we received so many questions around this topic. First, we need to separate the two parts of this question: the light source or light engine, and what I will refer to as the ‘color source’ or chipset1 for the purpose of this blog. I will keep this as short and simple as possible, but the two parts of this question will be broken up in this edition, and then in edition 3.

The light source, in this instance, is when you are looking at a lamp vs. a laser projector. Though there are still lamp projectors manufactured today, many of the top projection manufacturers in the professional space are moving to a laser light source. Why is this? Though lamp projectors are typically less expensive up front, the overall cost and maintenance of replacing lamp bulbs over the life of the projector brings the cost near equal. For reference, let’s say ‘Lamp-Based Projector A’ is $1,500 MSRP, and ‘Laser Projector B’ is $2,600 MSRP. The average projector lamp bulb only lasts 2,000 hours (8 hours a day, 5 days a week for about a year), so you will be paying to change the lamp bulb almost yearly. Additionally, the brightness (or lumens2) begins to fade over the lifetime of the bulb, which negatively affects the image and overall color accuracy. I have broken a light bulb that was $1.50 when trying to change it in my ceiling fan, so I also would not trust myself as a client to change a $900 bulb in a $3,000 projector every other year, which means someone has to roll a truck4 to change the bulb, further adding to the overall cost of ownership.

Laser projector brightness, or lumens, will eventually fade as well, but it is a much slower transition, and typical laser projectors are made to run 8 hours a day, 5 days a week for around 10 years (or 20,000 hours) with as little degradation as possible. Laser projection also runs physically cooler than a lamp bulb, which allows for higher brightness projectors to have longer lifespans, since heat and electronics don’t typically play nicely together over a long period of time. In commercial settings (read: anything other than your backyard projector movie night) I’d recommend going with a laser projector for the cleanest, longest lasting option possible.

QUESTION
I’m overwhelmed by the screen options out there. How do I know when to use each type of screen?
ANSWER

This is a great question. I was also completely dumbfounded when I first learned that projection screens were anything more than just a piece of blank white fabric. There’s actually a surprising amount of chemistry and sorcery that goes into each screen surface. If you’re going to buy tires for your car, you need to consider several factors to come to the right choice. Are you going off-road a lot? Do you need tires that can handle the snow? How often do you compete in underground drift races? Choosing the right screen requires a similar approach. Only by knowing the intended purpose of the projection system can you come to the right surface. In some cases, a standard Matte White5 screen will work fine. However, in many cases, using those screens will create some undesirable outcomes. I’m going to highlight two of the most common challenges we face in screen surface selection below. In a future post, we will look more into optimizing your screen surfaces to really get the best results possible.

  1. Laser Projection. Ashley just described all of the advantages of laser projection above. It’s not uncommon for an end user to upgrade to a laser projector without also upgrading their screen. This is a common mistake, and it can create some unfortunate consequences. A key concern is that here is an unwanted speckling effect when you use a laser projector on an older textured matte white screen (see image below). To solve this problem, many manufacturers have created tensioned screens with very flat surfaces. When upgrading to a new projector technology, it’s critical to also update your screen to one that is designed for that type of projection. Thankfully, our friends at Da-Lite have a screen surface technology chart available to help you with these questions.
  2. Ambient Light. Probably the biggest concern in projection is getting the system to be bright enough to get a quality image. You’re probably thinking that the best way to solve this issue is to just get a bright projector, and you’re not necessarily wrong. However, unless you have an unlimited budget (if you do, call me, I have some great ideas), that may not always be on the table. Other options here either are to use a screen that adds gain6 or to use an ambient light rejecting screen7. Screens that add gain use chemistry and witchcraft to make the screen actually appear brighter (usually done at the cost of limiting the viewing angle8). Ambient Light Rejecting Screens will block other wanted light sources (such as overhead light above the screen) from washing out the image. See Da-Lite’s Parallax screen below as an example. These are great options in rooms where there is a lot of sunlight or no controllable lights. Luckily, our friends at Da-Lite have a very handy screen brightness calculator to help you figure out the best screen for your space (notice a trend?). Again, we’ll explore some of the more application specific surfaces in a future post. There’s obviously a lot more to consider here.

Are these the most detailed definitions? No – we are not a dictionary, nor the AVIXA CTS Prep book. Will someone message us later telling us how much we missed? Possibly. After reading this post, will you have a basic working knowledge of these terms and why they matter? We hope so. Plus, we are 99% sure they help you school your uncles while you play Trivial Pursuit during the holidays. 🎄

  1. Chipset – Another widely-used term that vaguely means a set of electronic components that are wired together on a circuit. You will hear this term in regard to projectors, displays, but also anything from PCs to cars, to the fancy $400 toasters on Amazon that have a screen to show you how ‘toasty’ your bagels can get. You will hear this term more in Edition 3 if you want to Google it now.
  2. Lumens – Basically, this is a measurement of the light visible to the human eye. If you Google it, you will see some of the below terms, as well as more knowledge into the specifics of this term.
  3. ‘Lumière – Talking candle that lives in a mansion with a reclusive beast. 🕯️
  4. Roll a Truck – Fun way to say send out a technician to do a task in person, which translates into $$.
  5. Matte White – The most common, basic, and boring form of a projection screen. Probably what you had in your high school classroom.
  6. Screen Gain – The amount of additional brightness that a screen can add to the system. Usually measured as something like 1.1 or 1.3, which means that it can reflect back an additional 10% more brightness or 30% more brightness.
  7. Ambient Light Rejection (ALR) – Screens that have the ability to block out some or all light coming from top the screen. This means that sunlight or overhead ceiling light will not affect the projected image.
  8. Viewing Angle – A measurement of how far off to either side of the screen you can stand and still be able to see the projected image well.
