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.
