The International Telecommunication Union (ITU) has announced 
recommendations for an ultra-high-resolution television 
standard UHDTV with a sound system 22.2.
Two screen sizes are recommended:
- 3840 x 2160 (4K system)
 - 7680 x 4320 (8K system)
 
It is assumed that in Japan, such TVs will appear in 2013-2014.
The pictures for clarity show the ratio of these sizes with a standard TV (SDTV) and the current HDTV.
