Beyond HDTV – Way Beyond

April 12, 2007

NHKWe’ve discussed resolutions above and beyond 1920×1080 here before (several times actually) but this recent article from A/V Watch; referenced an older piece that provides additional details about Japan’s “Super Hi-Vision” HD system. For example late last year NHK broadcasting spiced up their 7680×4320 (yes that’s four times the current vertical HDTV resolution) Super-HD experiments, by incorporating 22.2 channels of audio and a proof-of-concept transmission method that used fiber optics to transmit the compressed 7680×4320 images onto 37.5’ screens.

100 lucky attendees took part in the demonstration and I do mean lucky, I’d give, well I’m not sure what I’d give but I would have loved to have seen this with my own eyes. Just incase your starting to feel a little buyers remorse over that lowly 1080p display device you just purchased; fear not, this system isn’t expected to even approach commercial viability before 2025 when 21GHz satellite transmissions become more feasible.

It was interesting to note that after one particular demonstration of the thirty-two million (not a typo) pixel display system concluded, applause could be heard next-door even through the presumably sound-proofed walls of the studio, quite a reaction. The head of NHK’s broadcasting technology laboratory went on to describe the reaction from those in attendance, the audience members described what they had witnessed as beyond television, likening it more to watching live performers on a stage. Yeah, I’d like to see that.

    JP, I don’t think this is something we’ll really ever see in a residential environment. This could however easily replace current 2K theatrical projection systems.

    I’m wondering whether the average person is able to see a difference between 7680×4320 vs 1920×1080?

    I read somewhere (can’t remember where) that it’s hard for some to tell the difference even between 1080 vs 720. Is this true (or can you comment on it)?

    Maybe there is, since I obviously see a big difference from regular old resolution vs current HD resolution, so why not from current HD vs the next gen resolution.

    Well, we can always dream.

    I would be happy with true 480i for SD and 1080i via satellite for HD.

    Like I said, we can always dream.
