The DVB Steering Board has approved commercial requirements for
the next phase of UHDTV, setting standards for HDR, audio improvements
and other developments to improve viewing.
DVB Sets the Stage for Next Phase of UHDTV
At the 81st meeting of theDVB Steering Board, commercial requirements for the next phase ofUltra High Definition Televisionwere approved, allowing the technical work on the specification to progress. The aim of UHDTV is to bring higher technical quality and greater realism to television viewers.
The path toUHDTVwas set in the ITU,International Telecommunication Union, in 2012 with a potential list of new attributes for future television, ITU-R BT.2020. Since then, DVB has developed, and continues to develop, systems to allow appropriate attributes to be practically delivered to the public. Another turning point for television has now been reached with the agreement on the requirements for a UHD-1 Phase 2 delivery format.
HDR, Audio, HFR
The first system developed by DVB in 2014, DVB UHD-1 Phase 1, opened the possibility for content providers to deliver services with images with four times the resolution of 1080p HDTV. This resolution is available and is in use, but in future it will be possible to also provide services with further characteristics to enhance the viewing experience. This is termed DVB UHD-1 Phase 2.
Defining Technical Specs
TheDigital Video Broadcastingconsortium, DVB, comprises over 200 broadcasters, manufacturers, network operators, software developers, regulators and others from around the world committed to designing open, interoperable technical standards for the global delivery of digital media and broadcast services. DVB standards cover all aspects of digital television - from transmission to interfacing, conditional access and interactivity for digital video, audio and data.
TheDVB Technical Modulemust now translate the Commercial Requirements into a technical specification for submission to the European Telecommunications Standards Institute, ETSI, for standardization. It is expected that the specification will be finalized in2016. This could mean that the first DVB UHD-1 Phase 2 services, that include the HDR capability, would be available from2017onwards.
