ITU has announced a new standard for High Dynamic Range Television that represents a major advance in television broadcasting.
High Dynamic Range Television (HDR-TV) brings an incredible feeling of realism, building further on the superior colour fidelity of ITU’s Ultra-High Definition Television (UHDTV) Recommendation BT.2020. 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.
“High Dynamic Range Television will bring a whole new viewing experience to audiences around the world,” said ITU Secretary-General Houlin Zhao, welcoming the announcement. “TV programming will be enhanced with brighter pictures that add sparkle to entertainment and realism to news coverage.”
“High Dynamic Range Television represents an important step towards the virtual-reality quality of experience to be delivered by future broadcasting and multimedia systems,” said François Rancy, Director of the ITU Radiocommunication Bureau. He congratulated Yukihiro Nishida, Chairman of ITU-R Study Group 6, for this major achievement.
The ITU-R UHDTV Recommendation BT.2020, approved in October 2015, represented the continuous evolution of television since it was invented in the 1930s, transforming the dim black and white screen into an ultra-high definition colour picture on large flat panel displays.
This latest ITU-R HDR-TV Recommendation BT.2100 brings a further boost to television images, giving viewers an enhanced visual experience with added realism. The HDR-TV Recommendation allows TV programmes to take full advantage of the new and much brighter display technologies. HDR-TV can make outdoor sunlit scenes appear brighter and more natural, adding highlights and sparkle. It enhances dimly lit interior and night scenes, revealing more detail in darker areas, giving TV producers the ability to reveal texture and subtle colours that are usually lost with existing Standard Dynamic Range TV.
The HDR-TV Recommendation details two options for producing High Dynamic Range TV images. The Perceptual Quantization (PQ) specification achieves a very wide range of brightness levels using a transfer function that is finely tuned to match the human visual system and the Hybrid Log-Gamma (HLG) specification which offers a degree of compatibility with legacy displays by more closely matching the previously established television transfer curves. The Recommendation also outlines a simple conversion process between the two HDR-TV options.
The ITU-R Recommendation BT.2100 also allows TV producers to choose from three levels of detail or resolution: HDTV (1920 by 1080), and UHDTV ‘4K’ (3840 by 2160) and ‘8K’ (7680 by 4320) – all of which use the progressive imaging system with extended colour gamut and range of frame-rates in ITU’s UHDTV Recommendation BT.2020.
“This Recommendation is the culmination of three years of intensive work by dedicated image experts from around the world. HDR images are stunning and this is another major step forward in television quality,” said Andy Quested, Chairman of ITU-R Working Party 6C (WP 6C), which developed the new standard. “Programme makers today need a much wider range of options in order to meet the expectations of the different platforms they must supply, and this need for flexibility is catered for within the framework of a stable ITU-R Recommendation.”
Kia makes car audio personal
KIA Motors has revealed its Separated Sound Zone (SSZ) technology that allows each passenger of a vehicle to experience an audio stream tailored to their individual needs.
SSZ technology creates and controls the acoustic fields of the car, allowing the driver and each passenger to hear isolated sounds. The many speakers installed in the vehicle feature technology that uses scientific principles to reduce or increase audio levels of sound waves. This negates the overlap of sounds being heard in each seat, creating the same effect as current noise cancellation systems, but without the need for headphones.
“Customers in the autonomous navigation era will demand increasingly customisable entertainment options within their vehicles, which includes technological innovations such as the Separated Sound System.” says Kang-duck Ih, Research Fellow at KIA’s NVH Research Lab. “I hope by providing drivers and passengers with tailored, independent audio spaces, they will experience a more comfortable and entertaining transportation environment.”
People’s musical tastes vary, so some passengers choose to use headphones during a journey to isolate their audio stream, but this also creates an unnecessary social barrier when interacting with other passengers. When travelling in a vehicle equipped with next-generation SSZ technology, each passenger can connect their smartphone via Bluetooth and listen to their own music without interference from, or interfering with other passenger’s audio streams.
When the SSZ is utilised, hands-free phone calls can also be isolated to individual passengers, ensuring privacy when having important phone conversations on the move.
Furthermore, this ground-breaking technology can eliminate unnecessary sounds for the passenger, but provide them for the driver. Navigation sounds, or various alerts, allow the driver to focus on controlling the vehicle, while the SSZ system isolates these sounds, maintaining a quiet area for the other passengers. This has a particularly strong application for drivers with a sleeping child in the vehicle.
SSZ technology has been in development since 2014, and the completed mass production system is expected to be ready for installation in vehicles within one to two years.

Future of TV in 4 letters
Television technology has come a long way, transforming not just the way we consume our entertainment, but also the formats in which media is broadcasted or streamed. Today, TVs can do a lot more than just display our favourite shows, says DEAN DAFFUE, GTM manager at LG Electronics SA.
Today, consumers demand TVs that are not just slim, but so thin that they are like paintings on walls. TVs have become an element of décor that can seamlessly integrate into the design of a home, and render the clearest, sharpest images, with the deepest blacks and crispest whites without compromising on resolution. Home cinema is not just about the picture anymore. Consumers are eyeing TVs that would be able to learn usage patterns and automatically suggest entertainment based on individual preferences. The switch from LCD to LED transformed TV design, allowing for lighter, thinner and easily wall-mountable frames, housing even more sophisticated display tech. The picture quality also dramatically improved with new contrast ratios rendering more vivid colours, deeper blacks and crisper whites. But they were still more functional than aesthetic.
As larger segments of the population embraced internet connectivity and streaming content, the TV became smarter, integrating content-streaming apps for a more seamless viewing experience. As Internet Service Providers (ISPs) upgraded their infrastructures to accommodate the growth in streaming services, TV manufacturers also upgraded their TVs’ ability to tap into different types of content.
In the future, TVs with built in Artificial Intelligence (AI) will be able to learn usage patterns and automatically switch modes based on user preference, and even take instructions from multiple users as TVs become increasingly connected to digital home assistant systems.
Six years on, and we see the evolution that continues to lead in the OLED TV market, LG is racking up awards and accolades for its innovative OLED TVs.
