The International Telecommunications Union (ITU) has announced a new Recommendation on the technical details for Ultra High Definition Television, with both 3840×2160 (4K) and future 7680 x4320 (8K) displays, getting the name UHDTV.
HDTV pictures today have the equivalent of between 1-2 megapixels. The 4K standard (3840×2160) results in a resolution of eight megapixels while the 8K version (7680 x4320) is 32 megapixels.
Christoph Dosch, Chairman of ITU’s R Study Group 6 said in a statement that “This is clearly a major achievement for ITU-R Study Group 6 of which we can be proud. The Recommendation means that organizations around the world can safely begin work to make UHDTV a reality.”
Squeezing a UHDTV broadcast into one 6 MHz, 19 Mbps terrestrial channel might be a challenge since UHDTV may require around 24 Mbps.
The timeframe for UHDTV to be available in domestic homes is estimated between 2015 to 2020 but Japan and China may get it in the 2013-2014 time frame. The BBC will trial UHDTV during the 2012 Summer Olympics, erecting 15 m display screens at three locations. The Los Angeles Olympics in 1984 was the first to use HDTV cameras.
