The HbbTV Association is a global initiative dedicated to providing an open standard for the delivery of broadcast and broadband services through connected TVs and set-top boxes. HbbTV 2.0.2 is an update of the second version of the core HbbTV specification and 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 MPEG-DASH. More specifically, the new release brings the following enhancements to HbbTV content
- High Dynamic Range (HDR), which dramatically increases the contrast ratio in video content, producing crispier 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 specifically 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.
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”.
