"Japanese telecoms firm NTT West is carrying out the world&amp;#039;s first 4K television streaming tests. The company is running the trial until the end of the week in an attempt to prove that footage in the ultra-high resolution can be transmitted to a set-top box, BBC News reports.  NTT West is using a compression technique to reduce the amount of data that needs to be exchanged to achieve 4K, which has four times the amount of detail as 1080p HD. The H.265 High Efficiency Video Coding (HEVC) standard works by discarding information that is not essential to how an image is composed, using an algorithms to fill in the gaps itself. This enables broadcasters to transmit 4K footage using much less data than usual, without compromising the picture quality. Leading television hardware makers, including Samsung and Sony, have already launched 4K-ready sets, but content taking advantage of the resolution is scarce. This problem could be rectified if broadcasters had the ability to stream content direct to set-top boxes. "^^<http://www.w3.org/2001/XMLSchema#string>
