Work completes on DVB-UHD standards


Standards governing the broadcasts of Ultra HD TV have been completed by the steering board responsible for Digital Video Broadcasting.

Today it was announced that at the 87th meeting of the DVB Steering Board, important revisions and updates for three DVB specifications were approved. The development marks the completion of the current generation of specifications for Ultra High Definition Television – DVB UHD-1. 

DVB UHD-1 covers elements for the improvement of video and audio quality for broadcast TV services: In addition to UHD (4k) resolution and a wider colour space, these elements include High Dynamic Range (HDR) for increased contrast ratios, Higher Frame Rates (HFR) for sharper images of moving objects, and Next Generation Audio (NGA) for the support of object- or scene-based audio schemes. The revisions and updates pertain to DVB-DASH, audiovisual coding and bitmapped subtitles. 

Commenting on completing the milestone DVB UHD specifications, Peter MacAvock, DVB Chairman said: 
“UHD is a key part of many broadcasters’ portfolios. DVB has worked tirelessly to finalize a comprehensive set of specifications for UHD. While work continues, DVB is certain that broadcasters can confidently implement UHD on the basis of its specifications".

The completion of a set of specifications for Ultra HD TV services will be welcomed by consumers wanting to buy a Ultra HD TV set in the future who want to be certain it conforms to certain standards and is properly supported as devices are made to handle a common set of standards, although other DVB specs relating to terrestrial, satellite, cable and IP broadcasts also come into play. Early adopters of new technologies can never be certain how future proof their devices will be, and whether they can make the most of new developments if industry-wide standards are not in place. For broadcasters, the standards ensure a common set of specifications across the industry they can work with, also in the knowledge that receivers in households that are compliant with relevant DVB specifications can make the most of their offerings including HDR and subtitles.
