Japanese company NTT, which is one of the biggest providers for cellular phones, has recently tested out international transmission of video in Super Hi-Vision format.

For those who are unaware, Super Hi-Vision has 16 times the resolution of full HD at 7,680 x 4,320 pixels. Here’s what else my Source says:

In the experiment, the signals were sent from NHK’s Science & Technology Research Laboratories in Tokyo to the US, Germany, the Netherlands, the BBC in London, and then back to an NTT lab in Tokyo. According to NHK, the signals traveled around 80,000km, with a time lag of just 0.3 seconds (time lag via satellite is said to stand at around 1.2 seconds). NHK currently plans to switch on test-broadcasting in Super Hi-Vision in 2020, saying that the technology could be used for public viewing of international sports events in Japan, for example.

The purpose of this experiment is to see if signals could be sent through the web, reducing communication costs and delivering higher definition pictures.
