Digital Video Broadcasting (DVB) is a suite of internationally accepted open standards for digital television. DVB standards are maintained by the DVB Project, an international industry consortium with more than 270 members.
DVB is widely used in Europe, Africa, Australasia, Russia, India, Asia (excl. China), and Middle East for digital television transmission over terrestrial, cable, and satellite networks.
DVB has developed a Content Protection and Copy Management system for protecting content after it has been received (DVB-CPCM), which is intended to allow flexible use of recorded content on a home network or beyond, while preventing unconstrained sharing on the Internet. DVB CPCM uses the ISAN as the content identifier to identify audiovisual contents.
More generally, ISAN can be used wherever a URN based content identifier is allowed in DVB. This is the case notably for the Material Identifier in DVB A167-2 Companion Screens and Streams where ISAN will be affixed in its URN representation in a Type/Value form. Example:
- Type: urn:schemename:isan
- Value: 0000-0003-68BD-0000-Z-0000-0000-6
To Affix ISAN with DVB refer also to Use of ISAN in MPEG as DVB uses MPEG streams.
