If you want to broadcast a TV show in 8K resolution, then you're going to need a whole room full of computers to encode the image. After all, a regular machine would struggle to process the 60, 35-megapixel images that need to be crunched every second. That's one of the many reasons that 8K video is currently limited to tech demos and the odd, one-off special event where the cost is justified. Japan's NTT, however, is claiming to have squeezed that room full of tech into a single box that's roughly the size of your average server module. Right now, the announcement is just that -- an announcement -- but this could mean we start seeing 8K broadcasts popping up well ahead of schedule.
