HD…And Then Some
Every show these days seems to feel the need to contain some talk about higher definition video formats than the 1,920 x 1,080 level we’re becoming used to now. But actually there was less such talk at CEATEC than we might have expected – perhaps because manufacturers are more mindful in these grim economic times of potentially scaring off people from buying into today’s HD ‘level’.
In product terms, the only higher HD resolution AV product making a serious song and dance about itself was JVC’s DLA-SH4K ‘4k 2k’ D-ILA projector, which was delivering the same demo witnessed at IFA to the same deliriously satisfying effect.
The commercial cinema possibilities for this projector are clear, though questions inevitably remain over exactly where any filthy rich home users might be able to find native 4,096 x 2,400 video content with which to get the best out of their new home cinema dream machine.
The only other significant source of higher definition chatter was Japanese TV giant, NHK. Remarkably, NHK has had a 7,680 x 4,320 pixel format called Super Hi-Vision since 2005 – backed up by 24-channel audio, don’t you know – that continues to fire the imagination of anyone who sees it in action. But don’t worry; the challenges involved with filming in, broadcasting, displaying and storing Super Hi-Vision are still to be overcome, so it’s hardly going to be something you need to worry your TV-buying heads about for some time yet – if ever.
