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
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
without having to buy a
bigger screen. We can see
for ourselves in Las Vegas!
