DVB-I DVB World DVB Services

Solutions

DVB specifications are used on every continent and in every country, with more than 1.5 billion DVB receivers in use.

The work of the DVB Project has resulted in a comprehensive list of technical and non-technical documents describing solutions required by the market to make the best use of digital broadcasting technology.

DVB standards support a wide variety of television use cases and solutions.

Key solution areas

DVB’s IP-centric ecosystem embraces broadband and mobile standards that, combined with the power of broadcast, can offer an ideal media delivery paradigm for all players. The middle area, with red and blue cross-hatching, shows how DVB Native IP bridges broadcast and broadband for delivery, while DVB-I, in yellow, provides unification on the service layer. (See key to diagram below.)

As shown above, DVB-I underpins DVB’s vision of a truly converged media delivery ecosystem targeting the full range of end-user devices.

IP-based delivery is handled via broadcast, multicast and unicast networks, combined seamlessly with existing MPEG-2 Transport Stream-based broadcast networks.

DVB’s audio and video coding specification (DVB-AVC) provides a further layer of interoperability, benefiting manufacturers, operators and end users alike.
