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.
Broadcast television solutions support traditional linear broadcast television delivered over one-way broadcast networks such as terrestrial, satellite and cable. Though using one-way networks, broadcast television can still be made interactive with embedded and broadcast applications.
Hybrid television is where broadcast television is enhanced by services delivered over broadband networks (e.g. DSL, DOCSIS, 4G). This includes IP delivered channels, on-demand content and other personalized services.
Broadband television is where all the services are delivered over a broadband network, which means they can be delivered to a wide variety of devices, going beyond the TV set and set-top box to mobiles, tablets, streaming devices and PCs – anything with a screen and a broadband connection.
Broadband television was originally delivered by the operator of the underlying network (telcos and cable operators). However today it is increasingly delivered over-the-top (OTT) of the network operator, direct from a service provider to the consumer.
Solutions & standards
The DVB solutions make use of different combinations of standards for the key elements. The broadcast solutions are primarily built on broadcast standards and the broadband solutions are primarily built on broadband standards. Hybrid television brings together the standards for broadcast and broadband to provide all of the required elements.
Interactivity is provided by the HbbTV system, which supports both broadcast-only and broadband environments.
