Good advert for LG (tv in background). THX dont seem to care like they did in the old days. I complained about a THX certified product not doing what its supposed to do and why they gave it a certification. I didnt even get a reply!

Head down ignore springs to mind. Bit like the fiasco with that certain rebranded dvd player which fails THX specs but still got a badge... hmmm bring back Mr Lucas :lease:

We will have quite a few videos coming in the next few weeks where we actually look at some of the testing. To say they don't care is a little bit unfair as we have seen what they do and they do care from what we could see. Who did you contact about your problem?
THX don't publish their specs and I can see their arguement for why that may be the case, I guess its up to them how they deal with that problem.

As for the Lexicon issue, I believe the specs do not at this present time cover the analogue outputs, just the video performance, processing and HDMI stage. This probably explains why the results were obtained. As far as I am aware, THX responded to the question of the Lex quite quickly to clarify things, yet Lex themselves have been less forthcoming. But that's another story for another day.

I hope you pop back and see the rest of the videos as I found the whole visit and the way they do things interesting. And they are one of the only groups to push for standards in both video and audio in the home and the display stuff is very good as far as I'm concerned.

I used their online form Phil. I asked them why they gave THX cert to onkyo 905 when the video board doesnt do what its supposed to. I provided links to forums where tests had been carried out. I emailed because they used to have a big thing about if you found a THX experience bellow par we want to know about it. I felt the video on the 905 let down my THX experience but they like onkyo couldnt give a rats ass :D

but I guess its ok cause that thx notice i cant find anymore, hence my bring back Mr Lucas as it was there back in the day.

sound/audio is not part of THX certification for dvd players? now thats a weird one. Has it always been that way?

agree with you on the Lex part. They must be embarrassed beyond belief. I wonder who was fired?

I hope you pop back and see the rest of the videos as I found the whole visit and the way they do things interesting. And they are one of the only groups to push for standards in both video and audio in the home and the display stuff is very good as far as I'm concerned.

will pop back for sure. I really appreciate your efforts on doing these interviews. Thanks :thumbsup:

I tend to regard THX as a load of fluff to be honest.
THX gets plastered over all sorts of mediocre and second rate transfers. (it used to even crop up on VHS!).

Reagrding the comments in the interview : I've been in plenty of THX cinemas that were frankly dire: sound from the cinema next : zero imaging over-inflated bass, crumby projection. Its just not a factor I take into account as a measure of quality.

On the audio fronts its some lose specs and some equalisation at best.

In my opinion its a marque in search of a reputation. They deviate from the standards without justifying or explaining their rationale other than in the most couched terms.

great vid

hope you show off some of their sound rooms

in relation to the bad thx experience in cinemas, isnt thx core purpose to recreate the movie as intended by the engineer through elimination of accoustic obstructions and reference audio/video; so a poorly engineered movie will sound/look exactly that... poor. i was under the impression thx doesnt enhance the media it just reproduces it as true as possible

i still notice it today when you can see and hear bluray/dvds which are just rubbish and some which are great.

Just watched this.

I hope that Phil has noted that I'm very quick to praise the hardware reviews and these videos, but this time...well that's a bit of a damp squib, I'm afraid.

It was fairly basic 'THX 101', and told me nothing new at all - indeed it was fairly Janet & John stuff, even by my own layman's standards - you can find out five times as much at their website.

In many ways I share Mr.D’s views about THX, but nonetheless they’re an interesting part of the overall AV jigsaw.

Having said that, and in the interests of balance, I note that it's only Part 1, and maybe the following part(s?) will offer us a greater insight.

Also, I am aware that there'll be those at these forums who don't know quite so much about THX, so fair enough.

Looking forward to Part 2, if only to see if things can be expanded a little.

Hopefully these comments will be seen as constructive and mild criticism.

THX state on their website that a 40 degree viewing angle for 1080p on a 16/9 screen ratio will give you an immersive experience. That seems to be the goal of THX to immerse you in the film maker's vision. I use a 40 degree viewing angle in my home cinema and it definately works for me :D

can someone tell me what cih is

CIW - constant image width as opposed to CIH - constant image height.
It's when you are talking about 1.85:1 movies (like Aliens) vs the more common 2.35:1 movies.
When you change from one to the other in your home cinema, does the screen expand and contract sideways to maintain constant image height, or does it zoom in and out to maintain constant image width.
Something like that.

The link in my sig below (Anamorphic Projection) is to one of the forums very informative videos which shows you a Constant Image Height set up being demonstrated. As Stuart alluded, CIH uses a 2.35 screen rather than a 16:9 screen.

I look forward to an end of these tedious "he said, she said" style discussions.

As has been discussed ad nauseam, THX do have a recommendation on viewing distance for HDTV material and they have concerns about CIH in the home related to user complexity rather than concern about correct presentation.

I am sure that anyone interested in reading more about this can easily dredge through the numerous spoiled threads across the forum where this has been argued over for the last 12 months or so.

Here is a fact that everyone can agree with - in your own home you sit the distance from the screen that you personally like the best.

I for one am past defending what XYZ technical group states (and I include myself in that that list of groups for sure).

I am certainly long past caring what XYZ obscure drector/cinematographer/office tea boy has to say on the subject.

I don't want to look up numerous old books to back up my personal point of view and nor do I wish to travel to any more meetings to discuss this subject with others.

I am satisfied, from my own experience in the field, that I have the relevant data required to deliver a satisfying home cinema experience to a paying client who has requested my technical input. What more do the rest of you hope to gain by continuing this discussion?

If someone wants technical advice for a design it can be given, but if someone wants to sit 20 feet from a 21" TV - who cares? If that is what they want then far be it from any of us to say it is wrong.
