ITU enhances TV viewing experience

The International Telecommunication Union (ITU) joins the world in recognizing the significant advances made in Television (TV) viewing experience in ways that are nearly unimaginable – as we celebrate World Television Day 2018.
With new advances in television technologies, tomorrow’s TVs will literally “outshine” today’s. They will allow even more detail in dark areas of the picture, and brighter highlights. 
ITU has been developing specifications that will allow broadcast and broadband services to use High Dynamic Range (HDR) television through a global standard. The result will be a greater sense of realism for viewers, giving television images a richer and more dynamic quality.
ITU has been the primary source of the basic specifications for Digital Television, High Definition Television (HDTV), and Ultra High Definition Television (UHDTV) specifications for the world. In recent years, work has continued with a standard (“Recommendation” in ITU) for HDR television systems, along with guidance for HDR programme production, and conversion between HDR and current High Definition (HD) systems. HDR can be applied to both UHDTV and HDTV images.
ITU’s work on making the television experience more immersive also goes further than the image. Advances in the use of compression have made UHD TV a reality for terrestrial, satellite and Internet delivery to consumers. Standards that combine Internet and traditional over the air transmission are creating a whole new television experience, while recently new sound systems have been launched, allowing viewers to locate the ‘apparent’ source of sounds from all around, above and below them.
“ITU’s work has a major impact across the telecommunications frontier, and a major element of this is broadcast and broadband media,” said Houlin Zhao, ITU Secretary-General.
“The media experience continues to expand to even greater levels of high-quality user immersion thanks to ITU’s study group on Broadcasting Services (ITU-R Study Group 6),” said François Rancy, Director of ITU’s Radiocommunication Bureau.
“The rich visual displays now available bring a real ‘sparkle’ to television viewing, in ways that television could be said to be ‘stepping into the sunlight,” added Rancy. 
ITU is also developing far more advanced Access Service options with the aim of promoting inclusion through the increase in the amount and quality of captioning, audio description and signing services. Standardization of these services by ITU leads to automation and ultimately, universal access service for all content.
Yukihrio Nishida, Chairman, ITU-R Study Group 6 said, “We make progress in ITU-R Study Group 6 thanks to our great team working collaboratively together to enhance broadcasting services for the benefit of everyone, everywhere. Personally I can’t wait to enjoy at home this new world of television images with High Dynamic Range, and the other exciting features we are working on.”
