Latest UHD TV specs approved




The latest specification for Ultra High Definition TV was approved in the 84th meeting of the DVB Steering Board (SB).

Ultra HD TV is still at an early stage and despite some UHD TV services already being available, work has been ongoing to establish common specifications to make the most of new technologies.

The industry consortium says the new specification is a major milestone for the industry, guaranteeing interoperability and enabling broadcasters and CE manufacturers to provide UHD-1 Phase 2 products and services. This could mean that the first DVB UHD-1 Phase 2 services, that include the new features, would be available from next year.

The specification covers various elements for the improvement of video and audio quality for broadcast TV services including High Dynamic Range (HDR) which significantly increases the contrast ratio and results in pictures with more 'sparkle'.  The DVB solution supports Hybrid Log Gamma (HLG) and PQ (Perceptual Quantizer). Furthermore, the new specification defines Higher Frame Rates (HFR), going beyond the current 50/60 Hz. HFR offers sharper images of moving objects. When it comes to audio, DVB has added the latest Next Generation Audio (NGA) schemes supporting object- or scene-based audio. These new features can be combined with HD 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 
“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. DVB views the Phase 2 specification as a key enabler for exciting products and services.”
