UHDTV reaches ‘tipping point’ with latest standard
WORLD: The latest specification for Ultra High Definition television was approved at the 84th meeting of the DVB Steering Board taking place recently in Geneva, Switzerland. The UHD-1 Phase 2 specification is said to be a major development for the industry and it's approval means that the first DVB UHD-1 Phase 2 services will be available from next year.
The new specification covers a number of elements for improving the video and audio quality for broadcast TV services, including the much-publicised High Dynamic Range (HDR). The DVB solution also supports Hybrid Log Gamma (HLG) and PQ (Perceptual Quantiser). Furthermore, the new specification defines higher frame rates beyond the current 50/60Hz. When it comes to audio, DVB has added Next Generation Audio (NGA) schemes supporting object-based or scene-based audio. These new features can reportedly be combined with HD and UHD resolutions.
‘Today’s approval of the specification is the result of enormous effort from the contributors, and further evidence of DVB’s leadership in the broadcast industry,’ commented DVB chairman, Peter MacAvock. ‘DVB views the Phase 2 specification as a key enabler for exciting products and services.’
‘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,’ added David Wood, chair of the DVB Commercial Module for UHDTV who oversaw much of the work on the specification. ‘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.’
