For those that don’t already suffer from high-definition fatigue, Japanese public broadcaster NHK is developing interactive and mobile technologies to make the idea of 8K video—the next resolution stage beyond 4K—more appealing.

At an open house event on Tuesday, the company’s Science & Technology Research Laboratories demonstrated an 8K satellite link with a camera on Tokyo Bay, and showed how viewers can make the most of 8K, a format it has been pioneering for years.

At 7,680 pixels by 4,320 pixels, the resolution of 8K, which NHK also calls Super Hi-Vision, is 16 times that of standard HD and four times that of 4K TVs. Uncompressed Super Hi-Vision signals can run about 24 gigabits per second (Gbps) or even 48 Gbps at 120 frames per second. It also has a 22.2 multichannel sound system.
