Spellbound fans are glued to the screen. Yes, this could be a goal for the German national team ... Oh no! Just past the post! Selected World Cup games were shown in razor-sharp clarity in ultra high definition (UHD) on domestic TV sets. For most of the time at least. Unfortunately, it is often the case that either the bandwidth of the transmission media cannot keep up with the data flow or the data simply cannot be processed fast enough. Then the picture judders or the high resolution has to be temporarily scaled down, and soccer fans have to make do with lower resolution images.

But very soon such low bandwidths could be a thing of the past. Researchers at the Czech Academy of Sciences together with their colleagues at Mainz University have discovered a way to dramatically increase data processing rates by around one hundred times up to terahertz speeds.
