How do you differ between the three?

Lumina Screens has been at the forefront of supplying projection screens that are optimum for a small-scale viewing experience. Providing a wholesome feel in limited space has been its target and it aims to fulfill it with sheer competence time and again. Proving its motives yet again, Lumina Screens installed three of its products at Annapurna Studios.

Annapurna Studios is a production house set up at Hyderabad in 1975 which produces Telugu films and television shows. It’s one of the earliest production houses set up in Hyderabad that solely served the purpose of producing Telugu films. It was founded by the late actor Akkineni Nageswara Rao. It has produced numerous hit films like Manmadhudu, Rajanna, Super and Mass which featured the Telugu superstar Akkineni Nagarjuna. The production house provides a platform for post-production to various other films and TV series, too.

For the kind of work the studio performs, it needs its requirement of quality and compatibility to be met; and for that, Lumina Screens proves to be the favored candidate. As it is commonly known that production requires excessive editing work owing to which there arises the need for the visual to look as clear as possible. Lumina Screens aids the process of delivering the top-notch visual quality through its flawless projection screen surfaces. Its range of products sure that the room environment doesn’t act as an obstacle when it comes to the compatibility of the projection screen.

Having a projection screen set up for various post-production tasks such as screening, editing, sound design, etc. is beneficial in a way because of comparatively bigger projection of visuals that go along with the surround sound. This helps the person working on the cut to accurately minister the visuals and work on it accordingly to the needs. The better the projection screen surfaces are, the better the overall output is. Hence, the color correction, CGI, edits look far better on a projection screen than it could look on a small LED screen.

Lumina Screens aims to provide the people with a perfect visual output at home or working space to give the effect of a traditional cinema theatre experience. With limited space, a person can enjoy or work on any visual they want to without any hindrance.

Lumina Screens is a part of Galalite Screens, under GTC Industries, that manufactures projection screens for a wholesome viewing experience at home, corporate offices, or auditoriums. Its vision is to reinvent the home theatre market with a cinema-like movie-viewing experience so that people can have an immersive watch with the comfort of home.

A home theatre addition to your home is not only a great investment in considering the calculation but also brings hours of enjoyment to you and your entire family.

With today’s busy schedules, especially for the ones with children, it is hard to coordinate time between school, sports practice, tuition, etc. It is very important to spend quality time with the kids which isn’t possible if you drive to a theatre only to wait in a long line for a “sold-out” movie. Then, because you are already there, dropping around 500 bucks (plain estimation for a family of four) to see a movie you really didn’t plan on seeing only to be disappointed because the acting or script was poor is a tiring experience — not to mention the 200 bucks you dropped at the snacks corner. For the same amount of money you spend at movie halls for a year, imagine how much you could otherwise spend on something you can actually enjoy without having to leave home and fight the crowds.

In this case, the best solution would be preferring ‘Home Theatres’ but many consumers are intimidated by this term. They think this means a lot of money, equipment, and cables running all over the place. However, with a little planning, assembling your home theatre can be easy, resulting in a setup that is organized, functional, and visually pleasing. Home theatre is commonly defined as an audio and video equipment set up in your home that emulates the movie theatre experience. In fact, a good home theatre setup may actually provide a more impressive experience that many of those small multiplex cinema screens.

There are at least 10 benefits worth considering home theatres for enhancing your entertainment experience. They are as follows:

• Privacy – It is a private venue for you, your family, and friends. You are in control of what is displayed.

• Shared Experience – It creates an environment for a shared experience and quality time with the family. If you have teenagers, it is a way to keep the kids home and avoid the outrageous ticket prices at local theatres. Also, having a place for your kids’ friends to hang out offers the parents the ability to keep a check on the activities of their children.

• Affordable Movie-Watching – The average amount of money a couple spends to see a movie in one of the two major theatre chains including buying drinks and popcorn is just shy of ₹600 for two people. Over the course of a year, a family of four that sees one movie per month would realize the ROI (return on investment) is equal to buying a projection screen that would work well in most home theatres. You can either download the movie on your tablets, mobile phones, PCs or use streaming services like Netflix, Hotstar, or Amazon Prime Video for watching the movie.

• Easy Installation – To set up a basic home theatre setup, you don’t need to depend on any third person. It is easy to set up and plug the home theatre systems according to the booklet that you receive while purchases these appliances or through tutorial videos from YouTube.

• Instant Entertainment – If you often find yourself sitting at home during the summer and bored enough, consider a home theatre. All you have to do is pop a downloaded movie or turn on your streaming video platform to enjoy quality entertainment without ever having to leave your home.

• Visual Clarity, Enhanced Viewing Experience – Nothing can compete with the resolution of projection screens, not even the best of Smart TVs available today.

• Favourites – After having a bad day at work, you can always retreat to your private theatre and queue up one of your favorite movies or iTunes playlists and then kick back and relax.

• Customization – Your home theatre can be designed with as many or few options as you can dream up. The latest technology allows for ultimate ease of use and customization of the timbre of the sound, style of theatre, and multitudes of seating configurations. You could tailor the sound system according to your listening preferences ranging from classical music to hip-hop with you at the controls for bass, treble, reverb, etc. of your sound system. You can equip your theatre with the latest in streaming video and music options including automated channel selections, timed on and off and environmental lighting and video controls.
  

• Awesome Gaming Experience – For those into video games, the home theatre offers an incredible experience, especially with those games incorporating surround sound. Video games like the Xbox One, PS4, and Wii can pull you in and make you feel like you are part of the action. The right equipment can immerse you in the game even further. The larger the screen, the more of the action you can see, and the surround sound gives you the one-up on your enemies by letting you hear exactly where they’re coming from.

• You Control the Schedule – You no longer have to rush through traffic to stand in line to buy tickets only to find that show is sold out. Your viewing schedule and time are totally at your discretion.

What is 4K, and how does it work? You may have heard the term 4K when exploring home theatre options, screen displays, and TV formats. But what is 4K and how does it work?

4K is an up-and-coming video technology that promises a better quality picture when you’re watching movies or TV shows. In other words, 4K means a clearer picture. It’s more pixels (8,294,400 to be exact) on the screen at once that creates images that are crisper and capable of showing more details than standard HD. 

The term ‘4K’ refers to the resolution of an electronic display. Specifically, it refers to the fact that there are roughly 4,000 pixels on the horizontal side of the display, which gives 4K four times as high a resolution as 1080p (i.e. what we call traditional ‘Full HD’ or ‘Full High Definition’ screens). And that’s why 4K is often called “Ultra HD” or “UHD.” The reason for calling it as 4K is because the images are around 4,000 pixels wide. And before you ask, yes, the industry named 1080 resolution after image height but named 4K after image width. 

Q: What is the resolution of 4K?

A: 4K resolution, at least the way most TVs define it, is 3840 x 2160 or 2160p. To put that in perspective, a full HD 1080p image is only a 1920×1080 resolution. 4K screens have about 8 million pixels, which is around four times what your current 1080p set can display. A full HD 1080p image is 1080 rows high and 1920 columns wide. A 4K image approximately doubles the numbers in both directions, yielding approximately four times as many pixels total. To put it another way, you could fit every pixel from your 1080p set onto one-quarter of a 4K screen.

Q: But is it really much better than 1080p?

A: Of course, it is! For a long time, 1080p was the industry standard resolution for online videos. So, when someone mentioned HD, they meant videos that were 1920 x 1080 pixels. But while 1080p content was considered “high definition,” 4K is considered “ultra-high definition,” and contains more pixels, conveys higher bit depth, higher frame rate, and a wider color gamut. This means finer details and a clearer image: so the more information that your video has (in this case 4K has four times, or more, the number of pixels than 1080p), the more opportunities you have to work on your video in post-production without losing the integrity of the original quality.

Q: Do all those extra pixels matter?

A: They matter very much. More pixels means more information. More information means sharper pictures. Sharper pictures are more engaging. More engaging content is more fun. Hence, it would be better if you could sit closer and enjoy the content in 4K because the ability to get up close to the screen without the image breaking down is one of the most intoxicating things about 4K. Sitting closer allows the same sized screen to fill more of your visual field, which yields greater immersion. The up-close factor is one of the reasons 4K computer monitors have become one of the technology’s fastest-growing sectors. 4K monitors remain pin-sharp even when you’re just a foot or two from the screen, as you are when you’re sitting at your desk.

Q: How 4K enhances the experience in a Home Theatre?

A: When the home theatre setup is installed on 4K, the visual experience would be enhancing into another level of visual experience, that founds in cinema halls. The 4K images or visuals offers four times the resolution of Full HD, pulling you right into the heart of the action with unprecedented clarity. It would help you to experience fabulously rich cinematic colors, smooth motion, and spectacular contrast. And it would be lower costs of setting up a home theatre with projection screens, than the televisions, in terms of maintenance and operating costs.

Q: Difference between Ultra HD and 4K.

A: Technically, “Ultra High Definition” is actually a derivation of the 4K digital cinema standard. However while your local multiplex shows images in native 4096 x 2160 4K resolution, the new Ultra HD consumer format has a slightly lower resolution of 3840 x 2160. This is one reason why some brands prefer not to use the 4K label at all, sticking with Ultra HD or UHD instead. However, the numerical shorthand looks likely to stick.

Q: So what can I watch in 4K?

A: Your best UHD options right now come from Netflix and Amazon Prime Video. Netflix is leading the 4K streaming waters with most of its original shows being available in 4K, alongside select films. The selection might be more limited than the amount of HD content, but it’s increasing day by day. Amazon has also gotten into the 4K UHD streaming game by offering some of its highest-rated shows in Ultra HD.

Both streaming services say even more content is on its way and expects the roll-out to ramp up once more TV watchers make the jump to the higher-resolution standard.

Q: So, what next?

A: The future of 4K consists mostly of improving what’s already there, rather than further increasing the spatial resolution, since there’s a near consensus that there isn’t much of a point in 8K. Instead, it becomes more common, the next steps by the industry would be mostly including additional frame rates, better color representation, and wider color spaces. From movies to sports or even video games, we can help your favorite experiences come to life with a custom-designed media room or home theatre.

When the lights in the movie theatre dim and cell phones are muted, the movie is about to begin. In the dark, you can hear an occasional cough or the rustle of candy wrappers and smell the aroma of buttered popcorn. The screen begins to reflect light. Welcome to the World of CINEMA, a world of make-believe made from moving images and digital sound.

One might sometimes think that what is the physics behind watching a movie? While a movie character often begins in someone’s imagination, the character’s image on the screen is a real image. Light rays shine onto the movie screen to produce the image we see as a moving picture. But how is such a big, clear, and moving image produced?

​Projecting the Best Image

Have you ever made a pinhole camera? If you have, you were projecting an image onto a flat surface. The image was small, dim, and upside down. The projector at the back of the movie theatre is similar, but it is a more complex optical device. It uses a very bright light source and lenses to project a big, bright image onto a screen.

Historically, all movies were recorded on film. The film—a long strip of translucent images—is positioned in the middle of a movie projector. Behind the film is a very bright lamp sitting inside a concave reflector. White light from the lamp is concentrated though two lenses— called a condenser—onto the film. The rays emerging from the condenser pass through the film. The images on the film act like a series of multicolored filters. The filtered light, carrying the image on the film, then passes through a series of lenses that spreads the light out and focuses it onto the movie screen. When the light strikes the screen, the image produced is therefore many times larger than the original tiny picture on the film. The movie screen then reflects the light that forms this image back to your eyes.

There were a lot of processes happens inside a traditional movie projector in order to project a moving image, like they have to follow the light from the lamp through the film and the lens. ​Until the late 20th century, movies were projected this way. The thousands of images that make up an entire movie were stored on a long piece of film. This film was wound on a reel and run continuously through the movie projector. The film was fed into the projector upside down and reversed left to right. When light rays shining through the film passed through the lenses of the projector, they crossed.

The picture on the screen, therefore, appeared to the audience as right-side up. The projector used sprocket gears that fit into the small holes in the edges of the film to feed 24 of these separate images past the lens each second. A shutter flashed each of these images onto the screen three times. (This means 72 pictures are projected each second. This flash rate is so fast that our eyes do not notice the images flickering on the screen.) When inverted by the projector, it appears on the screen in its correct orientation.

Modernizing Movies

These days, digital video has transformed the movie industry. The 2002 recording of Star Wars: The Attack of the Clones, on digital video, ignited a technological shift. Instead of traditional film, movies can now be recorded digitally onto a computer and stored on a DVD or Blu-ray. This makes the shooting, editing, and distribution of a movie much cheaper. Modern digital media can store information in a way that is less likely to degrade. Every time a traditional film is run through a projector, it may get a bit stretched or dirty. Except for scratches or breakage, a DVD retains its quality over time.

The digital movie is projected using either a micro-mirror projector or a liquid crystal display (LCD) projector. A micro-mirror projector uses millions of microscopic mirrors to form the images that we see on the screen. This technology still uses a very bright lamp, in this case, to shine light through a prism that splits it up into color beams. The beams are reflected off the tiny mirrors, which turn on and off in response to the video signals. An LCD projector also relies on light and mirrors; some things never change! A very bright light is reflected off a mirror that has an LCD on it. In response to the video signal, the crystals let some of the light through and block some of it.

Though these technologies are newer, they retain some of the original ideas from the invention of movies on film. Digital recording still relies on stringing together a series of images called “frames” in rapid succession to create a moving picture. While the moving image is not really continuous, our eyes and visual system interpret these pictures as uninterrupted.

In the modern era, home theatre technology keeps moving forward at a rapid pace. For the past few years, we’ve seen a huge reduction in cost for the latest audio and video technologies. You may have heard of these technologies like Dolby Atmos surround sound and 4K resolution with High Dynamic Range (HDR).

What does this mean for the home theatre you’re considering? You will require an installation professional or audio-video engineer that understands these technologies and the infrastructure that supports them.  Even if you’re not planning to take advantage of the new technology now, you want to be sure your installation will easily support them when you are.

If you’re upgrading or thinking about a home theatre room or wall space in your home, here are seven questions to ask your home theatre professional. Naturally we, Lumina Projection Screens are ready to help with the answers to these questions.

Q1: Is my room the optimal choice for sound production?

A: The first factor that you have to check out is a suitable room for the home theatre space. It’s easy to get carried away while buying equipment, only to get to realize that your speakers or are too big for your dream space. Sometimes you may discover halfway through staging your home theatre that your selected room is too small to accommodate your preferred components.

Therefore, it is important to discuss with your installer about the general dimensions of the room in which you want to set up your desired home theatre, and then block out where you want to place the various pieces of the home theatre. There are also several factors that your installer and yourself have to check about, like the space that you want to set up, prices of the appliances that you required and the budget that you have, and a sound check for all the equipment of home theatres to inspect whether is it audible or not, or is it disturbing your neighbours, etc.

Q2:  How do I soundproof my home theatre space?

A: Soundproofing is one important aspect when you have to foresee while creating your home theatre space. The simplest way to avoid the displeasure of quiet-loving people and neighbors around you is to have soundproofing paneling behind your speakers or television. De-couple your speakers, essentially by making sure an insulating material prevents their vibrations from being transmitted through walls and ceiling.

A more expensive method is to buy an amplifier that uses Low-Frequency Containment (usually referred to as LFC), that basically reduces frequencies that may resonate with common building materials, thereby reducing sound and vibration transmission through walls into surrounding rooms. It is important to ask your installer about the apt soundproof materials for your theatre space, and till how many frequencies does it handle, it’s advantages and disadvantages.

Q3: Will there be enough space between my projection screen and seating area?

A: In a cinema hall, if you feel that you’re too close or too far back – you can go to another row but it won’t be possible to move close or far from the screen – for that, you need to rearrange the furniture. It’s important to pick a good distance and to stick with it, but deciding where you want to sit can be complicated.

Ask your installer for help, like to calculate the distances between the projection screen and your seating area, what all equipment or setups have to change. Also, mention how much amount of space you thought so that the installer could work and give you the better choice.

Q4: Do I need special cabling to support 4K video?

A: It depends on the design and structure of your home theatre. It is not always possible to use regular HDMI cables – the ones that carry audio and video signals, in a custom theatre setup.

Depending on the length of wiring runs to your projector and audio equipment, you may need different cabling. One option is fiber optic HDMI cable, which can handle transmitting high bandwidth signals (the kind used for 4K video and high definition surround audio) over long distances.

Ask your installer about fiber optic HDMI and HDBaseT cables. These are cabling options for longer runs in theatres or media rooms and distributed video. The installer person should know and explain in clear terms why they should use or not use them for your particular installation.

Q5: Are there differences in speaker wiring?

A: There are a couple of standard gauges of wiring used to run through the walls for speakers. If you are an audiophile, you may want some high-end speakers in your theatre. There are some very high-end in-wall speakers and subwoofers, but few can match the sound quality of a floor-standing or high-end bookshelf model. These speakers benefit from thicker gauge speaker wire that can bring about their best sonic characteristics. In this as well as in other cables, distances matter too.

It is important to let the installer know your preferences, and what other uses the room may have, like watching sports and listening to music, that can make a difference in the wiring decisions. Lastly, don’t forget to ask about wiring for height speakers for Dolby Atmos – even if you may not employ it all the time, it’s wise to have your setup ready for that when you want it.

Q6: Will my home network just work with my theatre?

A: 4K video and high definition surround audio (like Dolby Atmos and DTS-X) require higher speed bandwidth than other formats. With the arrival of streaming services – be it 4K movies from iTunes, YouTube, Netflix, Amazon Prime Video and others – the capacity of your network could be possibly critical.

No one wants a 4K streaming movie getting interrupted, hence ask your installer about MIMO routers and dual-band versus tri-band technology. Ask whether the home theatre will rely on either wired or wireless technology, and why do they recommend it. Depending on your desires and the design of your theatre or media room, some combination of wired and wireless may be appropriate, and they should be able to explain the advantages of different approaches clearly.

Q7: Will your services and the cost of the equipment fit into my budget?

A: Firstly, before executing the plan that your installer and yourself worked out, the first thing you have to discuss is your budget – the amount of money that you are willing to spend for the whole home theatre setup. The installer will get an idea about your budget so that it could be possible for him to find out the best appliances under your budget and also to adjust his required wage as well. These kinds of discussions would really help you to set up a better-desired home theatre setup that you dreamed of.

We hope you start with us to ask these seven questions and many more about your home theatre installation. We, Lumina Projection Screens are at your disposal to help you out to assemble your desired home theater, to give you an immersive and enhanced visual experience.
