Milestone for Broadcasters and CE Manufacturers

Latest Specification for Ultra High Definition Television

At the 84th meeting of the DVB Steering Board the latest specification for Ultra High Definition Television, UHD-1 Phase 2, was approved. 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.

The specification covers various elements for the improvement of video and audio quality for broadcast TV services including High Dynamic Range which significantly increases the contrast ratio and results in pictures with more 'sparkle'.

The DVB solution supports Hybrid Log Gamma and Perceptual Quantizer. Furthermore, the new specification defines Higher Frame Rates, 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 schemes supporting object- or scene-based audio. These new features can be combined with HD and UHD resolutions. 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.”

The specification was a massive team effort with over 30 companies and other interested parties participating through the DVB Commercial Module, the Technical Module and the Steering Board. It is estimated that some 36 online meetings and 14 physical meetings took place over the 3 years. This commitment by DVB Members bears testament to how standards’ bodies play an important role and emphasizes the importance of getting consensus and wide approval for new standards.
