Despite enthusiasm at the box office and years of 3D TVs being available at affordable prices, the technology never really caught on at home. There are plenty of 3D Blu-ray discs still being released, such as " Star Wars: The Force Awakens ," but if you want to watch them at home you'll need a TV from or earlier -- or a home theater projector. We decided to drop 3D support for in order to focus our efforts on new capabilities such as HDR, which has much more universal appeal.
Sony's reply was similar, if less detailed. Those market trends are clear: Sales of 3D home video gear have declined every year since According to data from the NPD Group, 3D TV represents just 8 percent of total TV sales dollars for the full year of , down from 16 percent in and 23 percent in Native 3D-capable Blu-ray players fell to just 11 percent of the market in , compared to 25 percent in and 40 percent in My own anecdotal experience as a TV reviewer is similar to LG's. Over the years, the one thing most people told me about the 3D feature on their televisions was that they never used it.
Sure, some people occasionally enjoyed a 3D movie on Blu-ray, but the majority of people I talked to tried it once or twice, maybe, then never picked up the glasses again. I don't think most viewers will miss 3D. This is not quite a format war like VHS versus Betamax in the early s. Rather, each of these formats was designed to maximize the existing capabilities of their associated data transmission system.
Sequential 3D Sequential 3D consists of a sequence of alternating video frames where each successive frame is designed to be viewed by just one eye be it left or right.
For example, the first frame would be for the left eye, frame two would be for the right, frame three for the left again and so on. Such a sequence is a natural fit for active shutter 3D glasses. This format, which is driven by the Blu-ray 3D specification, allows for true p 3D images for each eye. What this means though is that the video must now be transmitted at 48 frames per second 24 for each eye to maintain HD quality.
As Blu-ray discs are hardly lacking for potential data storage, this massive bandwidth is not a problem. However, for this to work, some signal manipulation is necessary to work with the existing bandwidth limitations.
Side-by-side 3D consists of two full, horizontally-scaled images, displayed side-by-side on each video frame. These frames are transmitted at the normal HD rate of 24 frames per second. Each of these images is for the left and right eyes respectively. For p broadcasts with a aspect ratio, the left and right images will each be vertical lines wide by horizontal lines in height. When the 3D TV receives a side-by-side broadcast, it first separates the left and right images from each frame, then upscales the width of each by a factor of two.
Lastly, it displays the left and right images in a sequential manner as necessary for viewing with active shutter glasses. Due to the horizontal upscaling, side-by-side 3D is not as sharp as sequential 3D but as stated before allows for the use of existing equipment. In , DisplayPort 1. In version 1.
Additionally, it now provides improved HD 3D support through frames per second video frames per second to each eye as well as displaying the following 3D protocols: dual interface, field sequential, pixel interleaved, side by side and stacked. For more information on DisplayPort, read our November technical article. Moreover, HDMI's 3D support currently covers: frame, line, or field alternative methods; side by side methods full and half and 2D plus depth methods.

A parallax barrier is a thin, switchable liquid crystal layer that controls the direction of light leaving the display. Each of them touted the benefits of putting on a pair of clunky tinted glasses before settling in to a night on the couch, and presented as self-evident that their customers would clamor for the opportunity.
The technology had existed before; Samsung got there first, in But January presented a clear inflection point. In addition to the Cell TV there were 3D Blu-ray players, sets that could automatically give depth to flat images, and the promise of DirecTV networks that broadcast exclusively in three dimensions. The industry had lined up behind a vision of the future, marketing executives and product managers insisting that the more they had created was also better. How could it not be?
It was more. Five years later, 3D TV was dead. The iPhone was more transformative, but is also singular, and besides that was born in the late aughts. It was the dawn of all-internet everything, and all the privacy violations inherent in that. And it steadfastly ignored how human beings actually use technology, because doing so meant companies could charge more for it. What I remember most from those press conferences in was the assuredness that millions of people somehow actively wanted to have to put glasses on their faces in order to watch television.
Even then, it made no sense. And besides that, only certain types of shows—movies, maybe some sports—actually benefited from 3D in the first place. Or would, if the television sets were any good; most of the early ones stuttered and flickered even when you sat dead center in front of them.
