Ultra HDTV on Display for the First Time

fdiskne1 writes "According to a story by the BBC, the successor to HDTV is already out there. The resolution? 7680 x 4320 pixels. Despite the 'wow' factor, the only screens capable of using Ultra High Definition Television are large movie screens, and no television channel has the bandwidth needed for this image. Some experts, in fact, say the technology is only a novelty. Until the rest of the necessary technology catches up, the only foreseen use for Ultra HDTV is in movie theatres and museum video archives." From the article: "Dr. Masaru Kanazawa, one of NHK's senior research engineers, helped develop the technology. He told the BBC News website: 'When we designed HDTV 40 years ago our target was to make people feel like they were watching the real object. Our target now is to make people feel that they are in the scene.' As well as the higher picture resolution, the Ultra HD standard incorporates an advanced version of surround sound that uses 24 loudspeakers. "

  1. The final resolution jump? by w33t · · Score: 5, Interesting

    That's quite the resolution.

    I wonder, can the human eye even see such high resolution; does it even matter at that point? I mean,

    According to this page it would appear that each human eye is a 15 megapixel camera.

    If my maths are correctish then 7680 x 4320 is 33 million pixels.

    So then, the question is - does this mean that by adding both eyes together, at best humans have 30 megapixel resolution vision?

    Could this be considered "full human" resolution?

      The pixel density is higher than the eyes can see, unless it's taking up your full field of vision. But the other thing to keep in mind is that your eyes are essentially two cameras working in parallel. We subconsciously interpolate the information they're sending to create depth, but we also subconsciously interpolate the data to increase the resolution (and sharpen the image). Pick something in your room, take off your glasses if you wear them. It's relatively in focus, depending on how bad your prescription is. Now... close one eye, then the other. Notice that with both eyes open, the focus is better than it is with one eye closed, and it doesn't matter which eye is closed for that effect. Even if you're like me where one eye is near-sighted and the other is far-sighted. (My right is -0.50, my left is +0.25)

      I don't know the exact numbers, but we'll use the number of 15 megapixels per eye... just because a single eye is 15MP doesn't mean that both eyes working in tandem is going to be 30MP. In Astronomy, you can drastically increase the resolution of a picture you're taking by taking a dozen pictures spread out over a large area. If they're at the same time, then you can interpolate the missing data and produce a *really* high resolution picture. I'd be surprised if we aren't subconsciously doing the same thing with our eyes.
