T HbbTV announces UHD support he HbbTV Association, a global initiative dedicated to providing an open standard for the delivery of broadcast and broadband services through connected TVs and set-top boxes, has confirmed the immediate availability of HbbTV 2.0.2. This update of the second version of the core HbbTV specification enables HbbTV applications to benefit from new ‘Ultra High Definition’ video and audio technologies such as High Dynamic Range, High Frame Rate and Next-Generation Audio – delivered as streaming services using, e.g., MPEG-DASH. More specifically, the new release brings the following enhancements to HbbTV content: • High Dynamic Range (HDR), which significantly increases the contrast ratio in video content, producing crisper and livelier video. The specification supports both D-Book 10 Corrigenda released The DTG’s D-Book 10 January Corrigenda is now available. This additional publication from the UK collaboration centre for innovation in digital media technology has captured the most recent industry requirements since the launch of D-Book 10 in November 2017. Hybrid Log Gamma (HLG) and Perceptual Quantizer (PQ) coding. • High Frame Rate (HFR), which increases the current 50/60 frames per second to 100/120 fps. HFR offers sharper images of moving objects. This is especially useful in fast-moving sports content. • Next Generation Audio (NGA) technologies, which support object- or scene-based audio for a much more immersive audio experience.

The HbbTV 2.0.2 specification has been Key updates included in The DTG D-Book 10 January Corrigenda include HEVC Profiles for HD and UHD Broadcast services including High Dynamic Range (HDR), for both PQ10 and Hybrid Log Gamma (HLG), and High Frame Rate (HFR) content. There are also new DVB- DASH updates in Chapter 13, to correspond with the most recent release of the DVB’s Blue Books A001 and under development since October 2017, and it builds on significant work done in DVB during 2017. Many HbbTV devices already support these technologies today, but there has been no standardised way to use these features. The new specification defines a common, standard mechanism for accessing them from HbbTV applications. To promote interoperability of the newly added features, the HbbTV Association will order tests that are planned to be available in time for products going on sale in spring 2019. “With this new release of our core specification, we fill a gap in delivering broadband services to connected TVs and set- top boxes,” advised HbbTV vice-chairman Jon Piesing. “We enable the use of new, exciting audio and video technologies to deliver HD and 4K content with much better pixel quality to HbbTV-compliant devices.” A168, which are relevant for streamed IP services. “The D-Book 10 Corrigenda provides the requirements for broadcast HEVC services at a time when many more products are coming to market supporting this,” advised Peter Sellar, associate director, broadcast at the DTG. “While there are still no firm plans for HEVC broadcast service deployment yet in the UK, this will ensure that, when the time comes, there will be a stable population of products already in homes with minimal risks of future interoperability issues. In addition, the changes to Chapter 13, in support of HbbTV services, with the newly published DVB-DASH requirements, will support streaming services for our key stakeholders going forward.” eSTREAM 4K device from Evolution I ntegrated IP hybrid devices and IP video solutions provider Evolution Digital has introduced its eSTREAM 4K, powered by Android TV, an all-IP streaming box that delivers traditional cable services coupled with streaming apps from the Google Play Store.
