Draft:DVB-I


DVB-I is an open Digital Video Broadcasting specification for Service Discovery and Programme Metadata.[1]

The DVB-I specification[2] defines ways in which devices and displays connected to the internet can discover and access sets of audiovisual media services. These can include services delivered online through fixed and wireless Internet Protocol connections as well as broadcast radio and television channels received over radio frequency networks using traditional cable, satellite, or terrestrial transmissions.

DVB-I defines an online request and response mechanism by which available audiovisual media services can be discovered through a Service List Registry. The specification defines the schema and signalling to describe an ordered Service List of audiovisual media services, with provision for logical channel numbers and service logos, together with technical parameters by which one or more instances of a service can be accessed over various networks. It also defines methods and metadata to enable online access to programme information for channel schedules and programme catalogues that can be presented in electronic programme guides. This allows services to accessed in a coherent and consistent way over diverse networks. Support for regulated service lists provides a method for national regulators or their representatives, operators and trademark licensors to offer a list of trusted, legitimate, authorized, or regulated services.

As an open standard, based on HTTPS and XML, DVB-I can be freely implemented in any application, device, or display, enabling a competitive consumer market. It does not impose any form of presentation on how the information provided is rendered by the client. This may be supported directly by the software operating environment, a native application, or within a web browser. The HbbTV standard for hybrid broadcast broadband television has been extended to provide full support for DVB-I. Media services can be accessed using various established standards, including the DVB suite of specifications for satellite, cable, and terrestrial transmission, and DVB-DASH for online delivery using adaptive bitrate streaming.
