• Ultra High Definition Television

    According to an anonymous official at Japan's public broadcasting station NHK, a new television standard known as Ultra High Definition Television (UHDT) has been approved by the International Telecommunication Union (ITU).

    UHDT comes in two flavors, commonly referred to as 4K (3840 2160; 8.3 megapixels) and 8K (7680 4320; 33.2 megapixels). The terms 4K and 8K refer to the horizontal pixel counts.

    8K has 16 times the number of pixels as the current HD standard 1080p, and is roughly equivalent to 15/70mm IMAX. NHK has been a major driving force behind UHDT and is pushing the 8K version, branded as Super Hi-Vision.

    The format supports a broader palette of colors than HDTV, and also allows for frame rates of up to 120p.

    At this stage availability is so limited and expensive that it's no more than a talking point for most of us. The initial market is likely to be large public screens, and some test screenings have already occurred.

    For the wealthy early adopters out there, LG has promised an 84-inch 4K TV for about $22,000 USD.
