720 50-degrees, and means you cannot concentrate on all the screen at once, you start to look around – like real life! This is a different experience to HD. But the big question is will the public actually buy at least a 55-inch screen, re-arrange the furniture and view as closely as recommended? I think that’s unlikely. Use in home cinema is much more appropriate while keeping our SD / HD set to glance at across the room. While at NAB, visit NHK (booth: N231) and anyone else showing 8K. Ignore the crowd standing 9 feet back and watch at the recommended distance of 0.75 x screen height. They usually have an 85-inch screen so try viewing from about 31 inches (0.8m) away, creating a 100-degree viewing angle. My feeling is this is a bit too close, but 4 feet (1.2m) is fine. Both 4K and 8K UHTV require a great deal of further development to provide a complete scene-to-screen workflow. On the face of it the benefits of higher resolution are easy to understand and they can provide clear sharp pictures at a wider viewing angle, and so deliver a more absorbing experience – but not at a nine-foot range. But will 4K deliver a sufficiently enhanced domestic experience over HD to make it worth the engineering effort and customers’ money? There are also other possible directions for development, such as higher frame rates, which could enhance viewers’ experience without having to buy a bigger screen. We can see for ourselves in Las Vegas! TV-BAY MAGAZINE | 37 TV-BAY076APR13.indd 37 26/03/2013 16:47
