Joint Technical Committee (JTC) of the European Broadcasting Union (EBU), the European Committee for Electrotechnical Standardization (CENELEC) and ETSI Activity Report 2020
Chair: Antonio Arcidiacono, EBU
Responsible for the standardization of broadcast systems for television, radio, data and other new services, and for the standardization of programme transmission and receiving equipment.
ETSI plays a leading role in the development of specifications for technologies that are used globally for radio, television and data broadcasting. The specifications cover services delivered via cable, satellite and terrestrial transmitters, as well as by the Internet and mobile communication systems. Related topics such as Ultra High Definition (UHD) TV and interactive television are also included.
For many of these technologies, ETSI addresses two aspects: system and equipment specifications, and Harmonised Standards for equipment to be placed on the market in line with European legislation. In addition, for systems that use the radio frequency spectrum, ETSI works with relevant organizations to secure appropriate frequency allocations that are common throughout Europe.
Within ETSI our standardization of broadcast systems, programme transmission and reception equipment is managed by JTC Broadcast – the Joint Technical Committee that brings us together with the European Broadcasting Union (EBU) and the European Committee for Electrotechnical Standardization (CENELEC).
This work sees ETSI collaborating with other organizations in the broadcast domain, principally the EBU (European Broadcasting Union), DVB Project, WorldDAB (Digital Audio Broadcasting), DRM (Digital Radio Mondiale), RadioDNS Hybrid Radio, TVAnytime and HbbTV (Hybrid broadcast broadband TV).
In 2020 we accordingly continued to produce and maintain standards and technical specifications for relevant broadcast platforms and systems.
In an era of fragmented content consumption, TV and radio industries are looking beyond the limitations of traditional distribution models to satisfy today’s audiences. To maximize audiences, broadcasters are focused on providing the best quality content and service experience to users without being tied to a specific technology.
Published in December, our Technical Specification ‘5G Broadcast System for linear TV and radio services; LTE based 5G terrestrial broadcast system’ [TS 103 720] is intended to help broadcasters harness the fast-evolving capabilities of 5G radio and core network technologies to engage with their audiences. Leveraging existing 3GPP standards to enable the deployment of linear media services, the specification also offers implementation guidelines to broadcasters, vendors & infrastructure providers.
During the year the committee also issued several other new Technical Specifications. These variously cover DVB targeted advertising and hybrid broadcast broadband TV targeted advertising; DVB-Multicast Adaptive Bit Rate (ABR): adaptive media streaming over IP multicast; DVB service discovery and programme metadata for DVB-I; and DRM regional profiles.
Notable publications in 2020 addressed:
- DVB targeted advertising - dynamic substitution of content in linear broadcast
- [TS 103 752-1 & TR 103 752-2]
- DVB-multicast Adaptive Bit Rate (ABR): adaptive media streaming over IP multicast [TS 103 769]
- DVB service discovery and programme metadata for DVB-I [TS 103 770]
- Digital Radio Mondiale (DRM) regional profiles [TS 103 771]
Meanwhile we revised existing deliverables, addressing topics including DVB, DAB, Hybrid Broadcast Broadband TV and High Dynamic Range (HDR) systems for use in consumer electronics devices.

The process for the Publicly Available Specification (PAS) DASH-IF Content Protection Information Exchange Format [TS 103 799] progressed well. This specification is anticipated to be approved by JTC Broadcast with publication in April 2021.
