Broadcasters and service providers are preparing for the launch of Ultra HD (UHD) using the upcoming DVB UHD-1 Phase 2 specification. This shift will be the biggest change that broadcasters face since the launch of HD. With this move, comes a new delivery specification, UHD-1 Phase 2, which will include Wide Color Gamut (WCG), High Dynamic Range (HDR), High Frame Rate (HFR) and Next-generation Audio (NGA), bringing the quality of the UHD experience to an entirely new level. This paper will describe how content can be created to accommodate the new specification and will provide reference architectures that are planned for deployment. The presentation will also highlight the work done by the Ultra HD Forum for the first commercial deployments of UHD-1 Phase 2 in 2016.
The primary focus of this paper is to describe the different video options that will be used for broadcast or unicast over HTTP.
The discussions around HDR are speculative, but aim to provide insight into the HDR decision process within DVB.
Audio aspects will not be included in this paper, as they imply different techniques.
The discussion will focus primarily on a video signal, with p60 as the maximum frame rate, as some DVB countries are using 60 Hz and thus imposing constraints on processing power.
