DVB approves milestone Ultra HD specification The steering board of the Digital Video Broadcasting (DVB) organisation is claiming to have approved a new standard guaranteeing interoperability for Ultra HD (UHD)-1 Phase 2 products and services. DVB UHD The new specification is being hailed as a major milestone for the industry, guaranteeing interoperability and enabling broadcasters and CE manufacturers to provide devices containing new features to be available from 2017. The specification covers various elements for the improvement of video and audio quality for broadcast TV services including high dynamic range (HDR) and it also supports hybrid log gamma (HLG) and PQ (perceptual quantiser). Furthermore, the new specification defines higher frame rates (HFR), going beyond the current 50/60 Hz, and DVB has also added the latest next generation audio (NGA) schemes supporting object- or scene-based audio. These new features can be combined with HDTV and UHD resolutions. The specification will be published as BlueBook A157 and will be passed to ETSI for formal publication as TS 101 154 v2.3.1. Commenting on the new specification, DVB chairman, Peter MacAvock, said: Todays approval of the specification is the result of enormous effort from the contributors, and further evidence of DVBs leadership in the broadcast industry. DVB views the Phase 2 specification as a key enabler for exciting products and services. David Wood, chair of the DVB Commercial Module for UHDTV, who oversaw much of the work on the specification, added: When they draw up the history of television, the agreement by the DVB Steering Board to the UHD-1 Phase 2 specification will surely be writ large. It marks the culmination of many years work by scores of DVB Member engineers, and is probably the tipping point for the new age of UHDTV.
