The NorDig specifications cover four areas:

  1. NorDig Unified Requirements, specifications for IRD (Integrated Receiver Decoders which includes STBs, PVRs and relevant parts of integrated digital TV-sets), NorDig IRD specifications are established with the aim to ensure that IRDs in the Nordic and Irish market satisfy a common set of minimum requirements, independent of operator/service provider and transmission media.
  2. NorDig Test Plan, specification for how to verify implementation in NorDig Integrated Receiver Decoders. Common test specifications are established to ensure that decoders comply with the common minimum requirements. Additional test specifications may apply for individual networks, especially networks with access-controlled transmissions.
  3. NorDig Rules of Operation (RoO) provides requirements on the configuration of transmission parameters, including the related standards, to design transmissions of content interoperable with NorDig IRD. The Rules of Operation may also be used as a guideline by IRD manufacturers to understand how NorDig Broadcasters construct compliant transmissions.
  4. NorDig Metadata Exchange format specification – specifies a NorDig standard for EPG/Event metadata exchange format for B2B exchange of metadata between broadcasters / content provider, network operators and other stakeholder in the distribution chain based on TV-Anytime.

All specifications are based on DVB and the minimum performance sets that are specified for NorDig compliant networks. The use of the NorDig specifications is described in “About NorDig” at
