DVB, an industry consortium that develops open interoperable technical specifications for the delivery of digital media and broadcast services, has announced a new revision to its specification for the use of video and audio coding in broadcast and broadband applications to include solutions for HDR Dynamic Mapping (DM). The solutions allow a receiver, such as a TV set, to adapt a High Dynamic Range video signal to the characteristics of the display.

ETSI TS 101 154 is one of the core DVB specifications. It sets out how video and audio coding are to be used in satellite, cable, and terrestrial broadcasting systems, as well as in broadband delivery. The addition of HDR DM provides content creators and device manufacturers with a means of adapting video content so that it replicates as closely as possible the intended appearance, as produced in a reference viewing environment.

“DVB has provided the industry with the specifications needed to deploy UHD services with confidence,” said Peter MacAvock, chair of DVB. “HDR Dynamic Mapping is an important element of the ecosystem, helping broadcasters and other content providers to ensure their video looks as good as it possibly can on a given display.”
