Just as there has been much discussion on the merits or otherwise of B&O's picture quality and VFM in comparison with those of the larger manufacturers, I read today that Sky television has successfully tested 3D TV, able to be received on existing Sky HD receivers.

There will of course be the need to have a 3D capable TV, examples of which will apparently be exhibited at the forthcoming Consumers Electronic Show. I can only have sympathy for companies who are not one of the major players in consumer electronics as they try to keep up on both price and the very latest technology.  

Bang has always had a three dimensional picture with a quality exceeding most other manufacturers, so i think they have kept up quite well personally.

Regarding BangVision 7 MK1 (which appear to be being harshly critisised), at the time of release had a far better picture than any other LCD and in cases still does.

I would like to see what the term 3d means and how these tv's operate.  I cant see the picture being overly fantastic and i have a feeling that this is more than likely going to be a fad if not done properly (eg not being able to operate in most household conditions etc).

Lets wait and see what is going to be the new technology next week.

The tvs send out the two images using polarised light.  It will look like normal tv until you put on some daft looking specially polarised glasses to separate the images for your eyes to make you see 3D.

Same as the IMAX cinemas.

Dude1:

B&O has had a three-dimensional picture?

How do you mean?

It's not possible to display a three-dimensional picture on a two-dimensional display. 

3D!? SOUND THE ALARMS! DESTROY YOUR CURRENT TELEVISIONS!!! BURN THE ROOMS IN WHICH THEY SAT!!! DIG YOUR EYES FROM THEIR SOCKETS FOR HAVING GAZED UPON SUCH SIMPLE DIMENSIONAL RENDERINGS!!! QUICK, SOMEONE SHOW ME WHERE TO BUY ONE OF THESE TELEVISIONS! THIS WILL SURELY BE THE FINAL NAIL IN THE 8+ DECADE COFFIN NAILING OF DENMARK'S MOST FOOLISH ELECTRONICS MANUFACTURER!!! COMEUPPANCE FOR STRUER AT LAST!!!

OH. WAIT. You mean I can't see one of these televisions? You mean that such a product, if any interest even develops is 5+ years from market? You mean that the viewing angle is compressed back to a scant 60 degrees for the effect to work!? You mean that if you look at the television from the wrong angle, you won't see a coherent image at all?

Never mind. Wake me in 15 years when this technology is refined. Until then, stop trying to sell me crap that doesn't work yet. I'm too busy.   

Agree,

Let's make first lcd better,than we will see futher..

That is true, but the image reproduction on BangVisions using VisionClear technology has been designed so the image at the very front of the screen - say for example a person walking is far clearer and focused and the scenery behind that person is slightly less focused.  This and good use of contrast and colour give a almost 3d image to the picture quality.  No, the image is not out of the screen - but far better reproduced than most other manufacturers - check Avant / BV7-40.

This technology was designed to take into account that most of your vision when watching television concentrates on c30% of the screen. The rest of the imagein the screen our brain compensates for.  It also means that your eyes dont get so tired when watching the telly for long periods of time.

What about the new OLED technology? Is it an interesting alternative, and could B&O use the thin OLED panels to make interesting new Beovisions?

best regards

From what i've heard, OLED still is only suitable for relatively small displays

and there are still major issues with lifespan of reproduction of several colors.

I've never heard that this is what the Contrast screen was developed for.

Yes, it changes the contrast a bit, the colors slightly and with old CRT tv's it sure made the TV look prettier.

However, that the contrast screen would blur the image not in focus is impossible. The contrast screen is a total "dummy".

Blurring of the background is only done with the camera lenses aperture, and if the contrast screen was to blur the image, it would blur the whole image and not just the parts that are out of focus or background. 

Not sure I follow you.

 VisionClear is not only a contrast screen, that would be rubbish wouldn't it.

 I suggest you, take a look at a BangVision then compare the image with another manufacturer - do Sony as an example (its easy as the colours are radioactive bright, the screen eye burning bright and the focus overly sharp - giving you an eye catchingly bright and eye tiring picture).  Then you will see the difference B&O have put into their tellys. And, read the VisionClear definition on the website - it will help to put it into perspective - better than i can.

I agree partly that a camera will blur a background, as a general rule most televisions will keep everything in focus, where Bang will try at all times to give the picture real depth.

FWIW, we've just bought a Samsung 32" LCD to go in our lounge. The simple reason is that we can't afford a BeoVision, but for those who can, it highlights just where the price goes in a B&O TV. The Samsungs seemed to be the best performers, but they're still miles off the picture of a BeoVision. The difference seems to be even larger towards the larger-sized TVs.

VisionClear encompasses everything which produces the image on a B&O Television, from the Anti-Reflection Contrast panel in front of the display to the processing which sits behind it. The only way you can really appreciate the picture on a B&O TV is to get used to the picture they produce (as I have done) and then look at the brand-X offerings.

This is without even talking about the sound, integration or design/build quality.

Do you know this to be true? - this seems too good to be true. How do you determine depth of field in a 2D image, even if something is moving how can you tell if it is an eagle in the distance or a housefly on the camera lens?

I can understand dynamic control of colours, luminence, contrast and edge detection/sharpening etc. but what you describe seems incredible, especially in an analogue TV signal without a frame store.

I do know it to be true.

I measure quality of picture with my eyes.

With respect, the picture quality wasn't what I questioned, it was your claim the B&O TV's can somehow process foreground information differently to background.

my first ever "double post" 

sorry mods!

bingo, bango, bongo... i agree!

in simplest terms... "depth of field" and its relative focus is completely driven by the lens aperture at the time of the shot (photo or video)...

my sincerest apologies.

BangVisions do process foreground information differently to background, in most circumstances to varying degrees.  They have a hard time doing this on a shot of a football ground for example, as nothing is determined to be of more importance in the shot.  They do this more when there is an object that is dominant in the shot.

Processors do this by assessing information that is most relevant to the picture then "cutting" and highlights aspects of the picture by adding contrast ratios etc to add depth to the picture. It is simply demonstrated, by viewing one.  The Avant and BV7-40 are good demonstrators of this, of course this has been improved over time so naturally it is not as prevelant in older sets.

i, for one, would love a reference to the technical data supporting this...

enjoy.

...no mention of "re-focusing" foreground and background. 

i think you are reading too much into visionclear!

i think its refered to as peaking.

anyway this is getting boring.

Have a merry Christmas

yes, "peaking" is a component of visionclear...

but it is boundary modification for adjoining areas of color and contrast.

it has nothing to do with delineating between foreground and background and refocusing them to suit...

happy holidays, too!

OK, I'm happy with "peaking", it's edge detection and highlighting - a common signal processing technique in image processing. It won't do the foreground/background thing though.
