DVB-I (DVB internet, an ETSI-published DVB specification) lets a device discover and present linear TV and radio services delivered over IP, listing broadcast and broadband streams together in a single service list. This page covers how DVB-I service discovery works over 5G Systems, so that services carried by 5G Broadcast or 5G Media Streaming can appear alongside other IP-delivered content.
5G-MAG tracks this work and maintains related reference tooling, built by contributors including Fraunhofer FOKUS, Dolby Laboratories, Qualcomm and the BBC. The project has no repositories of its own: the reference tools linked below implement the delivery scenarios against the specifications this page describes.
The Problem It Solves
Without DVB-I, a broadcaster's 5G Broadcast service and its 5GMS unicast service would look like two unrelated things to a device, discovered separately with no common presentation. DVB-I's service instance model fixes that: one logical service can carry several delivery instances: a broadcast instance and a unicast instance for the same channel: and the device picks between them by priority, or, for a hybrid device already tuned to the broadcast signal directly, de-duplicates the two so the same channel doesn't appear twice. That is what lets broadcast and broadband content sit in one combined service list instead of two separate discovery systems a viewer has to reconcile themselves.
