Ultra High Definition Television Standards Drafted by ITU
Submitted by lalit on May 28, 2012 - 1:27pm.
ITU has announced a new Recommendation that represents a major advance in television broadcasting that will create an entirely new television broadcast environment with the advent of ‘Ultra High Definition Television’ or UHDTV. ITU’s Radiocommunication Sector (ITU-R) has developed the standard – or Recommendation – in collaboration with experts from the television industry, broadcasting organizations and regulatory institutions in its Study Group 6.
The quality of television pictures that viewers see has improved dramatically since it was invented in the 1930s. A dim black and white screen in the corner of the room has become the sparkling ‘high definition’ colour picture that we see on today’s large ‘flat panel displays’. But technology does not stand still. ITU-R Study Group 6 has now agreed a draft new Recommendation on the technical details for ‘Ultra High Definition Television’ or UHDTV which is now being submitted to Administrations for approval.
The ITU-R Recommendation lays out the quality standards for UHDTV in two steps. The advances made with each of these quality steps are roughly similar to the step from the old ‘standard definition television’ to ‘high definition television (HDTV)’. HDTV pictures today have the equivalent of between 1-2 megapixels. The first level of UHDTV picture levels has the equivalent of about 8 megapixels (3 840 x 2 160 image system), and the next level comes with the equivalent of about 32 megapixels (7 680 x 4 320 image system). As a shorthand way of describing them, they are sometimes called the ‘4K’ and ‘8K’ UHDTV systems. Ultra high definition picture quality is accompanied by improved colour fidelity, and options for higher numbers of pictures per second than for today’s television systems.
