Laser Light Engines, LLC, Again the First

Laser Light Engines Announces First Shipment of Its Universal Laser Retrofit System for 2D and 3D Digital Cinema
SALEM, NH– May 22, 2013 –

Jeez, just the heading. “Universal” must mean One Product fits all. That ties into the other press release LLE had on the same day, that they will be teaming with Elbit Systems of Texas to productize a system with the name of DSG265. We’re guessing DSG is for De-Speckled Green, but 265 stumps us. 256 we could have understood if this were an 8 bit system, or 255 perhaps…but DCinema is 12 bit. Hmmm. Marketing.

“Retrofit” is interesting as well. The concept of productizing anything for a market that is essentially completely full – over 90% digital saturation in some markets – there just isn’t going to be a lot of customers looking to trade-in for new projectors. There also isn’t an overwhelming reason to do so since many of the future options of lasers for projectors aren’t developed yet. Plugging into the existing optics works well enough until the mysteries of bi-refringent glass and spinning the photons off the mirrors solves the problems of darkening and softening caused by post-lens 3D filters. So, expensive ultra fast lenses and a lot of optics (that the next generation of engineers will laugh at) will have to remain – retrofit is the way to make the investment in the laser-based light systems work in 2013.

“2D and 3D Cinema” – To those who say that 3D is dead or dying, let’s remember that the studio’s latest arrangements with the Chinese government is to bring the tentpole movies in 3D…not just some, but 100% in 3D. Most of the cinema conversions are 3D capable there, and the 3D-capable percentage in Russia and parts of the EU are higher than in the US as well.

But 3D to work correctly needs more light to the eyes. There are few articles and only a little science on what causes headaches and other problems with 3D, but from those who have seen 3D movies with more light, it is more comfortable. Logic says that more light will make tired eyes strain less with a concommittant reduction in headaches and complaints.

“Announces the First Shipment” – has a nice ring to it after all the speculation and probable NIH competition since LLE made their despeckle announcement a few CinemaCons ago. It seemed obvious to many that the Kodak flash was never going to be productized, and possibly was a stock play writ large. But an actual shipment…and to whom? Enquiring minds, etc.

Having to wait for the lawyers and the marketing team of the customer can be a boring proposition for a company, especially one which wants to avoid the arrows (and worse) that many pioneers have to suffer.

Laser Light Engines, Inc., (LLE), a leader in laser illumination for high brightness digital cinema and performance projection, announced the first shipment of a fully configured RGB-laser powered Universal Laser Retrofit System to a leading global innovator in the cinema space.

“Leading Global Innovator” – Isn’t that a nice way of saying that they are smart enough to buy our product?

“The shipment of this system marks a big step forward for LLE, toward full commercialization of our universal laser upgrade solution for the nearly 100,000 global 2D and 3D digital cinema projectors installed over the past few years,” said laser projection pioneer Bill Beck, founder and EVP at LLE. According to the company, the multi-engine system incorporates LLE’s recently announced, flagship DSG265™ despeckled GREEN color modules, and provides constant brightness, outstanding image quality, brilliant colors and smooth, immersive 3D.

One would think at first that Mr. Beck was hyperbolizing a bit there, implying that 100,000 is the potential market for LLE’s light engine. In fact, in a sense he probably is, but in a sense he is probably understating the potential. There are 4 DCinema projector manufacturers who all sell projectors in far greater volume outside the cinema. They are joined by dozens of other manufacturers who use the same TI chipset (minus the security bits) for other than cinema projectors. Given the way that 3D is developing and getting less expensive on the production and post-production side, creation of 3D material can slip into many more markets, from architecture and product design to executive or music auditoriums to amusement rides.

Productizing is the key, and the market is really huge.

In addition to providing numerous image quality benefits, the LLE solution eliminates frequent replacement of expensive Xenon arc lamps, and can reduce wall plug and HVAC energy consumption. “The LLE multi-engine system is projector, chipset, resolution and frame rate agnostic, and is compatible with most major 3D systems,” Beck said. “And the light from the engine can be delivered via optical fiber cable, enabling flexible new cost- and space-saving deployment models.”

What isn’t being said is almost as loud as what was said in that paragraph. The discussions at recent demonstrations left one with the impression that some companies are not actually able to move the laser position on the frequency curve in a way that benefits both the gamut but also the wall plug efficiency, actually saying that their system wasn’t showing any benefit there, and that the cost of fans at the lasers was a wash with the reduction of savings at the projector vent. One presumes that one is hearing someone saying that the brute force method is all we can do and it works but it doesn’t work well…and come’on, the music moves the screen more than these screen shakers do.

It is just that one can’t help remembering the earthquake in the San Fernando Valley in 1994 when two earthquakes happened in close time and proximity. The joining of the concentric waves caused a much stronger reaction in a nearly straight line from the source points to dozens of miles away, to the extent of chimneys falling and houses being thrown off their foundations all along and to the end of that line, with much less severe damage a block away on either side.

Likewise, the patterns from the shakers was discernible after two weeks, with the light changing colors all along the path where concentric circles joined. Dont’ get the wrong impression; it was a brave and noble act to hold a 2 week demonstration of laser technology. Christie and their parent company Ushio should be lauded. The industry needed it. There is only one way to learn such things and groups should be given honors for taking the expense and the risk.

“Frame rate agnostic” means the future of High Frame Rate is secured and the rest of the PR is stating that compromises no longer have to be made. If history is a guide, the studios allow compromises with specifications until a manufacturer shows that the compromise is no longer required and then sets a date certain for not making prints in that format. MPEG to JPEG, the evolution of security keys and the disappearance of pre-ghostbusted prints all followed that path: one day accepted, one day ‘no mas’.

Resolution agnostic is interesting since it implies 4K, and sure enough – though it isn’t in this press release – if one goes to the LLE website and clicks on the coming event link on

June 11, 2013, 5:00pm
“Laser6P™: A New Laser Illumination System for Premium Dual Projector 3D”
Projection Summit
Orlando, FL

one sees in plain black and white that Mr. Beck of LLE will speak about “LLE was the first to demonstrate laser illuminated, “6 primary”, true 4K 3D with full color and resolution in November of 2012. Both DLP Cinema and LCOS 4K projector platforms have been integrated.”

As exciting as seeing the new RealD screen technologies in action with multiple screens at different angles and light levels, seeing any of the matrix of what that sentence speaks of would be very interesting. The implication is that others have already seen it in private demonstrations,  since the verbiage says ‘already been demonstrated’.

In addition to this major milestone for digital cinema, Beck said LLE will be shipping other new products in the coming months, including both cinema and non-cinema applications such as precision 3D metrology.

“Precision 3D metrology” – We haven’t yet seen anything of the industry’s attempt to create a precision metrology on speckle (or when the distortion goes from bad to unacceptable) and these guys are making products dealing with the measurement of 3D. Wonders never cease.

Boilerplate. Wish I had some. But actually, there is data in there. The beauty of boilerplate is that it is all lawyer vetted, so yes Alice, someone is thinking beyond retrofit and those lawyers are sure there is lower operating costs and less energy use in our future all from replacing xenon lamps with laser light.

SSL Certificates

This article is the beginnings of an article about SSL Certificates, what they look like, what they do, and what you should know so as not to be fooled.

The objective is pretty simple: To make it easy for the user’s computer to send and receive information from a site in a closed and secure environment.

Once a few steps are checked, the user can be assured that the data they are sending and receiving from the site is not going to be intercepted and mis-used. Most of the work is done by the “to be trusted” site, and one of a handful of 3rd party groups called Certificate Authorities (CA).

Now, in the digital cinema business the term certificate authorities comes up when speaking of the interchange of data between media server components and projector components. There are passwords (in the form of encrypted public and private keys) and encrypted data flying back and forth, and all refereed by CAs who follow rules set by a standards group or three.

The same is true in the web space, where keys are sent back and forth according to strict protocols. The user does’ t suspect any of this unless and until there is a gross problem. Usually the browser (Firefox, Safari, Chrome) notices certain clues that the sending site sends out, and if the browser doesn’t get more of what it needs for safe browsing it will either refuse to work or if it isn’t completely suspicious, it will tell the user the problem and ask the user for permission to continue.

Of course, absolutes don’t seem to exist…

On the DCinemaCompliance.net demo site, there is a certificate from one of the major CAs named Comodo. They are major enough that Firefox and Chrome and Safari recognize them. If we got all our friends together to set up a certificate authority, we could do so but the browsers would throw up an error…probably each time. The user would have to grant authority.

cert on dcinemacompliance.net siteThe picture of a cert as on the DCinemaCompliance site might look cool and official, but it means nothing significant. It might remind you to look at the URL and see if it has one important feature: did the “http:” change to “https:”. A site that doesn’t have that ‘s’ wouldn’t be secure.

What an https:// url should look like

You will notice that the URL is also colored green. It could also have a green or blue bar behind it, depending on which level of certificate was purchased from the CA. In this case the ‘s’ is showing so that indicates that a secure communication line has been created for the data to pass through. Without the bars behind it indicates that there is some material on the page that may not be completely secure, for example if there is a link to a non-secure site.

One should still be careful that there isn’t any of those famous key stroke stealing pieces of malware that can get whatever data you punch in. But that is the background of SSL.

The following two pictures show what happens when hitting the lock on a site with a valid certificate, and the identical site incorrectly using the same certificate…valid in one place and not another. Note that it will get goofy with questions if there is no means of qualification with a widely acknowledged certificate authority. There are private certs, but your browser will tell you and give you a chance to make your mind up about accepting them or not.

Testing!!! Audio Quality Control Possible (Meyer Sound)

a specialist in high quality auditorium sound which has been introducing a cinema-centric line for the last two years. They have worked with another specialist company, NTi Audio, a group that designs and manufactures handheld audio analyzers for the professional market.

The press release describes the new cinema meter option as adding a software package which includes a MeyerSound test script that can be used for tuning any cinema system. Test signals can be sourced through storage in the cinema system or from the NTi MR-PRO generator.

Post CinemaCon HI/VI Review–Sony CC Glasses

They did this by putting the letters into a small, see-through portion of both lenses and with a little magic sauce the words are suspended in the void between the viewer and the screen. The distance and font size and lateral position were all adjustable. And they were wonderful. But they needed refining and productization. The pairs that USL showed were made with 3D casting techniques that are not fit for production (fragile and expensive.) But the nice part was that they worked with the other equipment that USL has sold for years to the hearing and sight impaired audience members and the theaters who installed them.

At CinemaCon 2011 there was a wonderful off-the-exhibit-floor display of vendors who supplied equipment to the accessibility community. USL was positioned very close to the entrance of the room, but alongside Sony…who were showing a very refined version of the glasses technology that USL had been developing. What appeared to be happening was an interesting combo for exhibitors; the Sony glasses were receiving their signal from USL’s transmitter. But the glasses were light and nicely shaped and amazingly one could see the letters against the screen even in a bright room.

Expectations were that the system would be available around the end of the year…which came and went without any announcements. There were pictures that were smuggled out and passed around the community, but went unpublished even with the news that other vendors were taking orders around the globe. Some examples are the government grants purchasing equipment for hundreds of theaters in Australia and the recent announcement of complete fitting out of closed caption and descriptive audio or audio enhancement equipment at the complete chain of Marcus Theaters (675 screens in 56 theater locations.) Marcus Theatres(R) Completes Rollout of CaptiView(TM) and Fidelio(TM) Systems. Harkness and AMC have made announcements as well.

But Regal was quiet until they made the announcement at CinemaCon with Sony that they would be installing the new Sony glasses and audio system at all their theaters, with the intention of having closed captioning and assisted listening screenings at every show in every theater. Generally speaking this is not impossible but there are still difficulties on the distribution side. The greatest difficulty lies in the narration track which often isn’t completed until after the main movie is ready for shipping. Who wants to take responsibility for missing a release date because the narration track isn’t done? and how many languages are you going to hold the movie for?

Two years ago this dilemma was on no one’s radar. The promise of digital was gaining momentum everywhere but in the accessibility field. The basic standard was set out in the specifications, but they were made without any equipment being made to test whether the ideas worked in reality. Real world experiments proved that the smooth work flow that gave captions and audio in the analog world of film…with equipment that not only wasn’t available but wouldn’t work if it was…was capable of inconsistent jumbles in the digital world. USL’s engineers worked with engineers of other equipment manufacturers to work out compatibility problems during the times of transition between TI’s Series One and Series Two methods of creating letters and shapes accurately positioned on the screen from data files of text. Hundreds of hours of plugfests with no other manufacturer of HI/VI equipment showing up.

Against this background, USL becomes one of a million companies who help shape a technology and get the arrows of the pioneer as the reward. Sony announced that their clients preferred an all Sony implementation rather than a mixed vendor version. The new glasses system are sold with a receiver that also includes an audio jack so that this rechargeable receiver can also provide audio from the stereo assisted listening or the mono narrative tracks. But, they won’t supply the glasses and the audio headsets (not shown at the demo) at the same time.

Notwithstanding, a nice implementation. And yes, before you ask, 3D lenses can be used in combination with the glasses. The implementation shown at CinemaCon had a Regal logo centered on a flat set of lenses that were made to fit (if somewhat clumsily) into invisible grooves in the glasses frame.

Like Doremi, USL also makes a device that is mounted on a goose-neck that fits into the cupholder. As nice as these units are, and as nice as they have worked to block the light from interfering from adjacent seats…these are Model T implementations compared to the Sony glasses. There is no comparison to the comfort of not having to constantly look down and refocus to read the lines of text. Once an audience member gets used to using these glasses, that’s it. They will only go to a theater that supports them. In the United States, this is a good thing, since Regal has nearly 7,000 screens.

Regal has also put a lot of effort into working with CaptionFish, an online group who can guide the audience to open and closed caption screening times as well as note what type of narration equipment is available. Some narration equipment is able to work with the hearing aids of the user, and some users have purchased their own headsets.

It remains to be seen whether audience members will be able to buy their own glasses and listening device, letting the theater be responsible for the transmitter and link to the movie. One would think that it would be a great opportunity for a sponsor to get involved with partial or complete funding. They are more used to working with this model in the legit theater, which also supplies multiple languages for the scenes in opera or during plays.

All in all this is a wonderful time for accessibility in the US. In England, Your Local Cinema has helped the industry move along for some time there, but there is no great motion anywhere else in the EU…and the growth in accessibility seems stalled even in England. No one is talking of universal accessibility the way that Regal is. Perhaps it was the way that the lawyer who had lawsuits against them put it, when he gave his public presentation to the US Department of Justice. (In it he pointed out how minuscule the cost of accessibility equipment would be compared to the previous year’s corporate dividend.) Who knows? But it is a great thing to have happen after so many promises were broken for so long. In the end it is a mutually beneficial enhancement.

The Death of Silver Screens~! Vive la France

The 10-years-in-the-public history of digital cinema is marked with technology sitting below the desired standard, then reaching the possibility of displaying to the standard. The American Society of Cinematographers (ASC) pushed hard in those early days against the typical “good enough” mentality that normally plunges a technology lower to a new normal. Engineers from the industry came together under the auspices of SMPTE and AES, and assisted by an investment from the studios themselves to form DCI, developed a set of standards that aimed to match and better the qualities of film presentation.

Over time, Texas Instruments iterated the DLP up to the now wide-spread 2K, with excellent depth in the blacks. Sony followed with a different technology that brought 4K and an internal media block. 1.3 was relegated to the scrap heaps, the once king no longer allowed. Doremi showed that JPEG-2000 could be done following the standards and MPEG followed to oblivion, along with a few companies who couldn’t make the transition.

The studios are very careful to stay clear of any monopolistic tendencies. But they have an obligation to their clients, the authors and other copyright holders and directors to make certain that the people and groups who disseminate their entertainment does so to security and quality standards.

Which brings us to High Gain Screens in general, and Silver Screens in particular. They have the ability and purpose of focusing the light from the projector to reach the audience instead of the walls and ceiling and floor. That’s a good thing. But advantages in physics have the tendency of bringing undesired attributes. High gain screens have problems with uniformity. James Gardiner points out why in this presentation on his Cine Tech Geek–3D Quality on Silver Screens.

{youtube}bTuPSw7tKSE{/youtube}

One thing that James doesn’t elaborate on is that the ‘hot spot’ and uniformity problems of a silver screen are not just on the horizontal plane, but also on the vertical. So, as pointed out in 23 degrees…half the light. 3D What?, the viewer just 3 seats from the optimum seat is getting half the light level…whether 3D or 2D! and whether you measure 3 seats left or right or 3 rows higher or lower.

Higher or lower light means different colors. When the levels go from 48 candelas per meter to 10, they really change colors. Light Levels In Cinema – From the Screens Viewpoint. The reality is that most auditoriums don’t get close to 10 candelas (about 3.5 foot Lamberts.) You do the math, your milage may vary…as might your headache.

So, just like the ASC in the early days, there was a great hue and cry in France recently. As detailed in Silver Screens – French Quality Officially Declines?, the groups responsible for ensuring that the director’s intent has a fighting chance of being transmitted to the screen, found out that the standards body – the CNC – appeared to be throwing in the towel on the problems of high gain “silver” screens merely because (your author crudely typifies) the money had been spent.

As it turns out, the tide turned against giving in to inferior presentations with a structured requirement that Silver Screens be traded out as the technology turns the corner. Since Silver Screens deteriorate faster and can’t be cleaned at all, this happens more often than one would think…or it should. (A dark screen is going to make the dark problem even worse.)

J. Sperling Reich at Celluloid Junkie tells the story well: No More Silver Screens In France

At the start of a six day conference on technology in exhibition and distribution, CNC president Eric Garandeau announced an “agreement to ensure the quality of film screenings in movie theaters in the digital age.” In his opening remarks Garandeau acknowledged all the hard work that goes into making a movie and that, “if so many people put so much care to seek perfection in the image, it is necessary that these efforts are visible and even sublimated on the screen, in the most beautiful manner.” Wanting to see the difference for himself, Garandeau held a test screening to see “if a layman could make a comparison and tell the difference between a white screen and a silver screen.”

Garandeau says he saw the bright smile of Oscar winning actor Jean Dujardin switch from white to gray during the test and that the brightness level at the edges of the screen, compared to the center, decreased significantly. Not surprising since color balance, luminance consistency, and hot spots are the major drawbacks when it comes to silver screens, especially when they are used for 2D films.

Photipic Geranium's  Going Dark It is possible that the 6 day conference that Sperling mentions was actually the 6th Annual CST JOURNÉE DES TECHNIQUES DE L’EXPLOITATION ET DE LA DISTRIBUTION mentioned at CST 6th Day of Techniques…DCinema. One could also quibble about whether the ‘industry norm’ of 4.5 ftL is a legit number, since anecdotal evidence and reports from ASC members says the number is a lot lower. Whatever the case on those two issues, Sperling tells the most important parts of the French story extremely well.

Basically, what the CNC (and AFnor-Assn. Francaise de Normalisation) are saying is that they will be enforcing the long-known standard. The argument that there are financial implications should be invalid to a standards group, especially when it causes distortions in the playing field and possibly causes harm. By the transition date of 2017, all the existing silver screens should be replaced anyway. One would certainly hope that 3D technology will progress by then also.

Logic says that the decisions of the CNC should ripple throughout the world. The coming laser technology will allow high on screen light levels, even for 3D. Barco got nearly 90 candelas per square meter…over 25 foot Lamberts on a 70+ foot (23 meter) screen. Dual projectors are generally frowned upon for other reasons, but they have been used quite well in many cinemas to present high quality 3D movies.

When it is shown that the technology can perform the standard, the industry has prohibited…nay, insisted that the standards be followed. Whether that is actually significant for RealD and MasterImage in the long run is doubtful since the real money for their stockholders is in the consumer business.

It should also be pointed out that high-gain “white” screens have many of the same problems as a silver screen; if one is sitting on the left side of an auditorium, and if the screen is displaying a white field, one will notice that the opposite side of the screen is grey. The off-center gain structure can be just as bad. Why? Because high-gain creates as many problems as they solve, and the aluminum paint of the silver screen just exacerbate them. There may not be the hot spots that partially come from an imperfect paint application of the silver screen, and the screen may not deteriorate as quickly, and the white screen may be able to be wiped clean…or even have detergents applied without ill effects…none of which can be done with silver screens…but people off center are not getting the director’s intent.

One nice effect of all this is to see that the industry can talk about these things in the open. In the past anything that could spook the business was only discussed behind closed doors among the experts.

The Death of Silver Screens~! Vive la France

The 10-years-in-the-public history of digital cinema is marked with technology sitting below the desired standard, then reaching the possibility of displaying to the standard. The American Society of Cinematographers (ASC) pushed hard in those early days against the typical “good enough” mentality that normally plunges a technology lower to a new normal. Engineers from the industry came together under the auspices of SMPTE and AES, and assisted by an investment from the studios themselves to form DCI, developed a set of standards that aimed to match and better the qualities of film presentation.

Over time, Texas Instruments iterated the DLP up to the now wide-spread 2K, with excellent depth in the blacks. Sony followed with a different technology that brought 4K and an internal media block. 1.3 was relegated to the scrap heaps, the once king no longer allowed. Doremi showed that JPEG-2000 could be done following the standards and MPEG followed to oblivion, along with a few companies who couldn’t make the transition.

The studios are very careful to stay clear of any monopolistic tendencies. But they have an obligation to their clients, the authors and other copyright holders and directors to make certain that the people and groups who disseminate their entertainment does so to security and quality standards.

Which brings us to High Gain Screens in general, and Silver Screens in particular. They have the ability and purpose of focusing the light from the projector to reach the audience instead of the walls and ceiling and floor. That’s a good thing. But advantages in physics have the tendency of bringing undesired attributes. High gain screens have problems with uniformity. James Gardiner points out why in this presentation on his Cine Tech Geek–3D Quality on Silver Screens.

{youtube}bTuPSw7tKSE{/youtube}

One thing that James doesn’t elaborate on is that the ‘hot spot’ and uniformity problems of a silver screen are not just on the horizontal plane, but also on the vertical. So, as pointed out in 23 degrees…half the light. 3D What?, the viewer just 3 seats from the optimum seat is getting half the light level…whether 3D or 2D! and whether you measure 3 seats left or right or 3 rows higher or lower.

Higher or lower light means different colors. When the levels go from 48 candelas per meter to 10, they really change colors. Light Levels In Cinema – From the Screens Viewpoint. The reality is that most auditoriums don’t get close to 10 candelas (about 3.5 foot Lamberts.) You do the math, your milage may vary…as might your headache.

So, just like the ASC in the early days, there was a great hue and cry in France recently. As detailed in Silver Screens – French Quality Officially Declines?, the groups responsible for ensuring that the director’s intent has a fighting chance of being transmitted to the screen, found out that the standards body – the CNC – appeared to be throwing in the towel on the problems of high gain “silver” screens merely because (your author crudely typifies) the money had been spent.

As it turns out, the tide turned against giving in to inferior presentations with a structured requirement that Silver Screens be traded out as the technology turns the corner. Since Silver Screens deteriorate faster and can’t be cleaned at all, this happens more often than one would think…or it should. (A dark screen is going to make the dark problem even worse.)

CST 6th Day of Techniques…DCinema

The presumption is that a projector will be delivered, set-up and fit to the screen. But as the woman pointed out, more and more facilities are getting the projector dropped of, the picture is aligned to the screen and everything else is good to go…no colorimetry calibration.

She mentioned that many maintenance contracts lacked this initial colorimetry calibration. The odd part is that many of the maintenance agreements preclude engaging a 3rd party for this calibration.

The installation groups on the panel did point out that they include a yearly calibration.

Your author has been hearing this story for 5 years, at least.

The digital world brings a lot of advantages, but in this area there are many things that are not objective.

This article is a work-in-progress since it is simple to go to a thousand tangential problem areas from these few facts. There is even talk of a breakthrough on the CNC silver screen problem.

There may be a lot of overtime for the SMPTE Police.
