HbbTV Association Publishes New Version of Core Specification to support HDR, HFR and NGA

Geneva(21 Feb 2018)
The 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, today announced 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 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 specification supports both AC-4 and MPEG-H.
The HbbTV 2.0.2 specification has been 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 standardized 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.
Commenting on the new release, HbbTV Vice-Chairman Jon Piesing said, “With this new release of our core specification, we fill a gap in delivering broadband services to connected TVs and set-top boxes. 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”.

About HbbTV Association (www.hbbtv.org)
Hybrid broadcast broadband TV (or “HbbTV”) is a global initiative aimed at harmonizing the broadcast and broadband delivery of entertainment services to consumers through connected TVs, set-top boxes and multiscreen devices. The HbbTV specification is developed by industry leaders to improve the video user experience for consumers by enabling innovative, interactive services over broadcast and broadband networks. The specification uses elements of existing specifications from other standards including OIPF, CEA, DVB, MPEG-DASH and W3C. In June 2014, the activities of the Open IPTV Forum (OIPF) were transferred to the HbbTV Association. This broadened the HbbTV Association’s mandate to include defining specifications for service providers and technology suppliers that streamline and accelerate deployment of IPTV services.
