DVB-I and DVB-MABR published as ETSI standards

ETSI has this week published two of DVB’s new landmark specifications as formal standards. TS 103 770 specifies Service Discovery and Programme Metadata for DVB-I Services and TS 103 769 is for Adaptive media streaming over IP multicast. Both DVB-I and DVB-MABR will feature strongly during the DVB DEMOS 2020 event on 26 November, with live demonstrations of implementations from several different vendors.


The DVB-I Service Discovery specification defines the mechanisms to be used to find sets of linear television services delivered through broadband or broadcast mechanisms, as well as methods to retrieve electronic programme data for those services.

DVB-I services can be consumed on any device with a suitable internet connection and media player, including TV sets, smartphones, tablets and media streaming devices. While they may be delivered by broadcast or broadband, DVB-I services are more likely to be those delivered via broadband IP using DVB-DASH.

Multicast ABR

While unicast streaming is well suited to unsynchronized media consumption, or consumption of linear streams by smaller audiences, multicast streaming enables IP-based linear media distribution that is both efficient and scalable to very large audiences.

DVB-MABR (Multicast Adaptive Bit Rate) specifies a reference functional architecture for an end-to-end system that delivers linear content over IP networks in a scalable and standards-compliant manner. Scalability is achieved by means of IP multicast operating in parallel with and alongside conventional unicast delivery.
