DVB has published a new version of its DVB-I specification, DVB BlueBook A177r7, which defines the framework for discovering and delivering television services over broadband and broadcast networks.
The update comes against a background of increasing interest in DVB-I platform. Several trials and pilots are currently running as broadcasters grabble with how to combine linear television and on demand viewing experiences.
In a statement the DVB explained the latest version of the specification introduces a number of important enhancements, including:
- Support for signalling applications that can gain, renew, or withdraw user consent for the terms of service associated with a chosen service list – functionalities that are crucial in the context of GDPR and broader data protection requirements.
- A new application type for “Application in Series,” enabling applications to run before media presentation begins.
- Mechanisms that allow the DVB-I client and the application providing media presentation to share information and controls.
- Support for configuring CMCD (Common Media Client Data) client reporting for DVB-DASH delivered service instances, facilitating better network and playback optimisation.
- Methods for DVB-I endpoints to identify non-standard extensions using schema-based and identifier-based approaches.
- The ability to signal service lists compliant with different versions of the specification in the service list registry, helping to ensure a stable market as new clients and server updates are introduced.
In parallel, DVB has also published an updated version of the Implementation Guidelines for DVB-I, issued as BlueBook A184r2. This new release adds guidance on several key areas to support implementers.
The publication of these updates comes amid a broader effort to support DVB-I deployment. Earlier this year, DVB launched a dedicated DVB-I Implementers Task Force to help companies bring DVB-I services to market, fostering collaboration and sharing best practices
DVB BlueBook A177r7, an interim draft of ETSI TS 103 770 V1.3.1, and the updated Implementation Guidelines in BlueBook A184r2 are available for download from the DVB Specification Library.
