The DVB Steering board will next month be asked to approve the publication of UHD-1 Phase 2 (TS 101 154).
It follows the backing of the organisation’s Technical Module of the specification that covers improvement to the video and audio quality for broadcast TV services. High Dynamic Range (HDR) significantly increases the contrast ratio and results in pictures with more ‘sparkle’.
The DVB solution also supports the two quantisation curves defined in BT.2100: Hybrid Log Gamma (HLG) and PQ (Perceptual Quantizer). Furthermore, the new specification defines Higher Frame Rates (HFR) going beyond the current 50/60 Hz. When it comes to audio DVB has added the latest Next Generation Audio (NGA) schemes supporting objects or scene based audio. These new features can be combined with HD and UHD resolutions.
The DVB said the new specification is a major milestone for the industry and enables broadcasters as well as CE manufacturers to provide UHD-1 Phase 2 products and services.
