hi Doug
no….it turned out to be a lot harder then anticipated.

[Gregg Loewen]

hi guys

Ron, yes I am the person that accepts / rejects the certification application.
I spoke with Paul at THX yesterday. They are still finalizing the process for plaque purchase etc….any time now.

Each calibration submitted will have a $100 fee associated with it. (the first 10 are free…and ones done solely for the purpose of getting the 10 in for certification do not count towards the 10 freebies).

Initially, you will have to fax your order in (that will need to be linked to an online submission of a report that I will have certified) and THX will mail out to you the plaque, certificate, and Demo DVD.

Hopefully VERY SOON. I too have 10 plus clients that are currently waiting on plaques etc.

Stay tuned….i will give out more specifics when all is finalized.

hi Ron
My apologies, I have been in vegas for 1 week now….argh…trade shows.
The only hold up right now is the THX Calibrated plaque status and I have sent an email out asking for a status update (they should be ready to go).

[Gregg Loewen]

DVE – HD Basics in Blu Ray is a great disc. Almost all my clients now have some sort of BluRay player so I am using it daily.

Amazon.com sells it for $18.00.

hi guys

in the Detroit airport now.

I got an email from Stacey (the webgoddess) last night saying the submission form for calibration approval is now live. On my log in I can see that I have the “betas” for approval but can not personally see where I need to click to to make a submission. Anyhow….

The THX staffers have been working at this real hard and all should be finalized very soon.

Questions to be finalized:
1. where do we submit our calibration reports for certification
2. where / how do we get our calibration kits to give to our clients.
3. how / when do we get our names on the THX site as being Level 3V certified (attended training and passed exam vs both and submitting the 10 reports).
4. clarification on the name of the training level (as I am aware, it is Level 3V).

Doug, does that summarize your questions ?

Let me know if not.

Stay tuned.

Gregg

hehe…cool
Last time Hometheaterforum went to LA, THX hosted us for a day. they took us through the DVD production process, from telecine, to digital correction, to DVD authoring (DVD encoding etc etc), to DVD production, To final product. It was one of the best days of the week long meet.

[Gregg Loewen]

hehe….you have to love tire kickers.
On a related note…always put your best foot forward…you never know when the investment will come back to you. Here is an example of some of that which I received in an email a couple of days ago:

Hey Gregg,

Thank you for the quick response. I almost called you back instead of emailing, but as it is a long weekend I thought this better.
Yes the last week of June works very really well, I will do as you suggest to book a spot.

I am very familiar with your name. It’s somewhat interesting how I came across it. Years ago,1984 to be exact, I purchased a Kloss Nova Beam, model 1A. After a few years I happened across a gentlemen who ‘tuned’ up these sets (I remember he started with grey scale, then went on to do a number of adjustments which took several hours). His services weren’t near what calibrators do now a days . But I vividly recall how incredible the display looked after he was done.

Years later, I purchased a Toshiba 65H80. A few years after that purchase, I recalled how incredible my Kloss looked after it was adjusted. So I did some online research and came across a number of articles regarding calibration, ISF and the like. While doing this research I kept coming across your name. The other name I often came across was Michael Chen. I believe you’re familiar with him as well? 😉 I read a number of posts, mostly customers whose TV’s you calibrated. To say they were very positive would be quite an understatement. All in all I became quite familiar with your name and services.

Fast forward about six years or so to early this week, at which time I took delivery of that sammy, I thought why not have the best possible picture? This lead to me to do a search for a calibrator in my area. Much to my surprise your name popped up. I felt like I had hit the jack pot!

I do have two questions regarding my TV and would like your opinion. I’ve been following an online forum regarding this set as well as a few other sammy DLP’s (http://www.avsforum.com/avs-vb/showthread.php?t=971265&page=117). A number of the posts have dealt with a bowing issue some of these sets seem to have. When I received mine, I accessed the service menu and brought up a white horizontal line pattern. On this set the very bottom horizontal line, in the middle, it is 8/32″ from the bottom bezel of the set. At the both the left and right end it is 14/32″ from the bezel. So about 6/32 or really 3/16 of an inch of bow at the center of the screen.

Also, those white horizontal lines, the closer the line is to the top of the set the more red you see just below the white (very similar to convergence being off on my old set). The lines at the bottom you see only white. About 1/4 of the way up you start to see a bit of red. As mentioned above the further up you go the more red you see.

My two questions are; is bowing something that can be adjusted? Many a post at that forum say no, but so far I have not seen an expert comment on it. Not being an expert I wonder how much of a problem it really is? That is to say, how often while actually watching a program or DVD, are horizontal lines going to be displayed, and displayed long enough that one would be able to notice it? I only noticed it when I got close. But on the flip side, I also wonder with the present bowing, and if it can’t be adjusted, might that negatively affect other adjustments?

My second question; the red I see just under those white lines, same question, can that be adjusted as well?

Reason I ask these, I bought this set from crutchfield, and they have a pretty good return policy. Of course I’d rather not, but if it is necessary I have no problems returning it for a replacement set.

In closing, my apologies for the long email, thank you for your time, and I look forward to meeting you.

Mike

[Gregg Loewen]

if the site will let you…go for it.

also, we are about ready to have the automatic form submission working for getting your calibrations certified.

[Gregg Loewen]

hi Doug
I dont think it is ready yet. I will definitely post here when it is (and will also do a group email).

[Gregg Loewen]

hi guys
I will let John respond to your concerns for the “official word”.

Q&A With Dr. Michael Rudd, Chief of AV Architecture at THX Ltd.
It’s been a while since we last conducted a formal interview with THX and we decided to pick up the phone and speak with Michael Rudd about the new THX Certification Display program. THX Display Certification primary goals are to drive quality in manufacturing and help simplify consumer buying decisions. According to THX, having a single testing methodology and specification enables display manufacturers to standardize on one benchmark that is recognized by both industry insiders and consumers alike. We put THX to the test with a series of questions we had about this program to ensure it wasn’t just another logo branded on a product to pimp sales.

The industry has come a long way since the disheveled patchwork theaters of the 80s. While THX is well-known for its audio prowess and ability to provide some very helpful standards and DSP post processing, what exactly makes THX now qualified to contribute standards and features to display manufacturers?

Many people recognize the THX brand from the “Audience is Listening” tagline and our work with AVR and speaker manufacturers. What they don’t always realize is that we’ve been working with the visual side of movies for many years. In fact, close to 90 percent of our DVD post-production work has focused on ensuring stellar image quality throughout the mastering and production chain. And we have been fortunate to work on some of the world’s biggest DVD releases, including Star Wars and many of the Disney-Pixar films. We also spearheaded the development of standards for video switching, transcoding and scaling on AVRs and preamps. But it wasn’t until a couple of years ago that we started playing a more visible role in HD consumer products with the launch of the THX Certified Display program with Runco, Vidikron and Sharp.

Why create such a program? What value does THX bring to the video world?

For the average HDTV shopper, finding the right display can be a daunting process. You have to navigate the various formats, technologies and marketing claims, not to mention the massive wall of HDTVs at your favorite electronics retailer. We believe THX certification offers a simple value proposition to the consumer: if a display or projector is THX Certified, it will deliver exceptional performance regardless of price point, brand or display technology. We also feel that creating such a standard of excellence allows manufacturers to differentiate their premium products from less performing, competitive offerings.

Delivering the very best entertainment experience is what our original mission was, and still is today. With today’s technology, there is little reason why every pixel created in the professional environment can’t be replicated in the home along with great sound. And with the THX Movie Mode, featured on all THX Certified HDTVs, we’re providing consumers a very simple way to experience this kind of quality.

Who is heading up the THX Certified Display Program and what are their credentials?

[IMG]http://www.audioholics.com/education/display-formats-technology/MichaelRudd_Headshot001.jpg/image_mini[/IMG]When we started working on the display program, there was already a very experienced team of video experts in place from our work in DVD mastering. But, we made several additional hires, including engineers with credentials from some of the industry’s top flat panel display manufacturers. For this program to succeed, we felt it was necessary to have a team with a depth and breadth of experience, including intimate knowledge of post-production and consumer electronics. I currently lead the THX Display team. My background is a mix of audio and video applications in both the military and home theater sides of the business.

We know THX likes to keep its exact testing super-secret, but what can you tell us about how you are putting displays through the THX process for certification?

There are several key ingredients to THX testing and certification. We have great testing engineers and some of the best laboratory-grade testing gear in the world, including Quantum Data Signal Generator and Photo Research Spectro-radiometers. We also have very tightly-controlled testing environments, black rooms where stray light does not affect testing and a dedicated home theater lab. In addition, we use both PC and Mac-based systems for generating our proprietary test patterns in uncompressed HD.

The specification itself is divided into Device Performance and Signal Processing Performance, so we look at both picture quality and video processing. The testing starts during the early stages of product development. If we don’t get involved early, it can be difficult to make the necessary changes to the display before it goes into mass production. When the first pilot-run displays are available, they are tested in the THX laboratory. Usually the displays are accompanied by a factory engineer, who can adjust the firmware whenever it doesn’t meet some of our testing criteria. No display has ever passed the THX certification first time out-of-the-box.

How much work did THX put into coming up with original testing material to use with testing displays?

[IMG]http://www.audioholics.com/education/display-formats-technology/THXLab_DSC0099finalCMYK001.jpg/image_mini[/IMG]The device measurements were developed in accordance to the SMPTE, IBU, VESA and ANSI guidelines and evaluate such things as a display’s brightness, contrast, uniformity, convergence and viewing angles. While these tests are based on recognized industry standards, we created our own methodologies for quantifying items like deinterlacing, scaling and motion conversion, areas that had been previously tough to pinpoint. We produced custom designed patterns to enable the repeated evaluation and quantification from product to product.

Today, many companies still rely on a set of “golden eyes” to judge a display’s signal processing abilities. We opted for a more objective approach. We created special animated test patterns to expose any weaknesses in a display’s deinterlacing, scaling and processing features. For example, our deinterlacing patterns use moving fields of alternating colors to identify how a display responds to moving content. The variety of testing materials and patterns are designed to allow us to actually place a numerical grade on signal processing performance.

Are you going to have across-the-board black level minimum requirements? Minimum contrast ratio requirements? Color gamut minimums?

We do have minimum requirements in all of the key areas that you mention and many more. Our black level, contrast and color gamut performance requirements are based on SMTPE research and recommendations, which are professional video standards for screening rooms. Because a big part of the THX certification is recreating the cinematic experience, we felt that defining levels within the professional industry specifications would be the best way to bring that experience to the home.

Will you require or encourage support of new color gamut features like xvYCC? If these are included will you test for them? What kind of 12-bit source materials will you be using to test xvYCC?

Yes and no. Yes, we are encouraging display manufacturers to support xvYCc, but no we are not yet requiring it for THX certification. We feel that xvYCC offers a compelling way to describe color gamuts which are larger than Rec.709. However, Rec.709 is still the mandated specification for HD mastering today and there is currently no home entertainment content produced in the xvYCC format. For that reason, the Rec.709 color gamut is required for all THX Certified displays. If this type of content were to become available to the consumer in the future, then the xvYCC format would be very valuable.

How does THX movie mode differ from recommended ISF calibration recommendations? Is more involved than simply setting correct black levels and attaining a 6500K color temperature?

We consider THX Movie Mode to be the best out of box experience possible. And since we test and evaluate each product, this setting is consistent across all display technologies. THX Movie Mode sets the red, green and blue primaries (color management), the luminance, as well as the black level, the correct value of gamma and correct tracking of the white-point with gamma. We opted to use white point instead of color temperature, since it is more precise. Many of these parameters are not accessible to consumers even from the service menu. So, THX Movie Mode provides them a simple way to get the right settings with just a push of a button. In addition, THX Movie Mode ensures that a display complies with the HDTV standards and will present HD content correctly.

Will you be involved in testing the compatibility of HDMI inputs with other equipment?

We do check the functionality of the HDMI input on THX Certified Displays. It’s important that a THX Certified Display is exceptional both in terms of video quality and compatibility with source devices. All THX Certified products, whether they are speakers or HD displays, are designed to be compatible with each other. Since HDMI has become such an important feature on new HDTV products, it is necessary for us to check the basic functionality.

Panasonic already makes excellent televisions, as seen by measurements of color, black level, etc. How much did THX do (and in what areas) to improve the new Viera line?

We get this question a lot. And, the truth is, we never give out specifics about what THX testing has improved in a particular manufacturers’ product. It just wouldn’t be fair to our partners. However, I can address the question more generally. Since its inception, the THX Certified Display program has been adopted by LG, Panasonic, Runco, Vidikron and Sharp—all premium brands. Thus far, the areas where we bring the most value are improving uniformity performance, color primaries and gray scale, and signal processing. Regardless of the brand, we always find areas that can use some improvement.

How does your testing vary across display formats (front vs. rear projection, plasma vs. LCD)?

It’s no secret that there are inherent differences between display technologies. So, creating one specification that works across all display categories was the biggest challenge we faced when developing this program. For example, a THX Certified LCD must meet the same, tough contrast requirements as a THX Certified plasma—without compromise. Even though our testing and certification is technology agnostic, we do pay closer attention to certain areas than others with specific technologies. We explore image smearing more extensively on LCDs, and rainbowing on single-chip DLP front projectors. The goal is to present a consistent, high quality viewing experience on each THX product across all categories.

Roughly how many different tests are run on a THX certified display?

[IMG]http://www.audioholics.com/education/display-formats-technology/THX_VideoTesting1001.jpg/image_mini[/IMG]The specification covers about 400 data points and close to 30 tests. We start by getting the color imagery correct, then work our way through contrast, brightness and standard user controls. The video signal processing tests are performed closer to the end of the testing cycle. Because we have been able to automate much of the data acquisition, testing can be completed in just over a week or so.

We actually list all of our testing at: http://www.thx.com/products/home/displays/testing.html.

Are there now, or are there planned to be, different levels of THX certification for displays?

We have only one level of certification performance across all display categories.

Since deinterlacing, scaling and motion/video conversion is handled by literally only a handful of companies (Silicon Optix, ABT, Gennum, Faroudja, SIL, etc) is it possible that certain video processors will fail your tests entirely or will you test within the confines of a manufacturer’s design or a lowest common denominator?

Our standards for video signal processing were developed independent of any particular chipmaker’s performance claims. However, we have evaluated products from all of the major manufacturers that you mentioned, and as you might expect, we have found differences between them all. Because there is such a wide choice of settings, such as filter selections, one particular chip can work differently in different display products. For this reason, we have to work closely with the display manufacturer’s engineers to optimize the settings of a selected chip for a particular display model. We apply the same standards to all chip manufacturers and we have failed displays that contain processors which do not meet our standards.

What new HDTV products will feature THX certification? And when are they shipping?

We have two new lines of THX Certified plasmas from LG and Panasonic shipping in the next few months. The Panasonic PZ800 series, which features the 42-inch TH-42PZ800, the 46-inch class TH-46PZ800 and the 50-inch class TH-50PZ800. From LG, we have the PG60 Series, which in the US comprises the 60PG60 and 50PG60. This is exciting for us because these models will be the first THX Certified Displays available through traditional retail chains. Hopefully, Audioholics will get the chance to give them a good workout.

[Gregg Loewen]

cool
nice ending.

[Gregg Loewen]

cool. Isnt the Progressive Labs software $1800 ??

[Gregg Loewen]

they are still working on it (as far as I am aware).

[Gregg Loewen]

all the codes are on this site (see the service menu area).

I have not had time to work on this idea further. The remote that I had programmed (and was using on the Samsung in class) lost a page of its programming. So this idea wont work unless i can get a remote that is web based or PC based where the calibrator can restore any lost data in a method that is close to real time.
