Head of Technology, 5G-MAG Project Office · Senior Project Manager, EBU

Hi, I'm Jordi-Joan

I'm a telecom engineer working on how video, audio and immersive content reach people over the internet. I have contributed to standardization efforts and currently work with the industry translating specifications into open-source software.

What I do

Now · October 2026

5G-MAG Project Office

Running a global industry association

I help run 5G-MAG – The Media Connectivity Association day to day: member projects and activities, workshops and events such as the Future Media Townhall at IBC, and relations with members, the media and international fora.

3GPP · DVB · ATSC

Writing the specifications

30+ technical contributions since 2011. Most recently, feature lead for time-frequency interleaving in 3GPP RAN1 Rel-19 for the EBU.
