DVB Group publishes new specifications for IP delivery

The new specification includes support for signalling of 5G services as well as signalling of accessibility services and of HbbTV applications for accessibility

The DVB Group has published updates to two of its DVB BlueBooks related to DVB-I, the internet-centric system for delivering digital broadcasts.

BlueBook A177r6 is the latest version of the DVB-I service discovery specification; and BlueBook A184r1 is the first revision of the implementation guidelines for DVB-I.

The new release of the DVB-I specification itself includes the following updates:

  • Signalling of accessibility services and of HbbTV applications for accessibility;
  • Signalling of a service provider’s homepage;
  • Support for signalling of 5G services, addressing gaps that had been identified in the deployment guidelines for DVB-I over 5G (TR 103 972 V1.1.1); and
  • Bug fixes and clarifications arising from industry trial activities.

The updated specification is accompanied by an update to the DVB-I implementation guidelines, BlueBook A184r1. Additions in this first revision of the guidelines include:

  • Examples of the use of the extensibility mechanism provided in the DVB-I Service List;
  • Information on how an app should obtain service lists for regions where the user is not currently located (i.e., when roaming);
  • Clarifications on the use of parental rating information at service selection and programme boundaries; and
  • Information on the anticipated use of the service provider homepage information.
