Belkacem Teibi: an Engineer focused on innovation

DR - @inria

Belkacem Teibi's work at the LEELCO Innovation Lab combines the world of research and the world of business. He develops marketable solutions to deliver live audio and video content on large sets of mobile devices. The LEELCO Innovation Lab brings together researchers from the Privatics team and Expway to drive forward the transfer of innovative technologies.

What does your role at the LEELKCO Innovation Lab involve?

Belkacem Teibi : I've been working for LEELCO (Low End-to-End Latency COmmunications) with Vincent Roca, a researcher in the Inria Privatics team, since 2015. This joint laboratory, set up by Inria and the company Expway and funded by both organisations, has defined a joint work programme.
We work on the transmission of digital content to large numbers of mobile devices. We want to deliver a robust solution to manage data packet loss in this kind of situation. The aim is to rebuild any lost packets using algorithms. So, we have two problems to solve: first, we need to deliver good broadcast quality to a large number of devices and, second, we need to reduce induced end-to-end latency as much as we can, to enable more or less live broadcast. For example, one day we may see our services being used to broadcast sports events.

So in fact your job combines research and industry: is that something that you have always wanted to do?

B.T. :I didn't hesitate for a second when I was offered the job of technology transfer and innovation engineer. It's the perfect step forward for me. I have two Masters degrees, one in research and one professional. In my final year of study, I did an internship at Capgemini and then I worked at startups, mainly in Rennes, at a startup that developed a solution for checking customer identity before allowing them to take out a contract. I worked on product development, mainly to develop this service on tablets and smartphones. But I always wanted to pursue my career in research. I found LEELCO particularly interesting since it's a widely-recognised, very successful international project. We are helping to improve standards in our sector. So, I enjoy both the freedom of a researcher and the pleasure of developing new tools that will be available on the market.

What projects will LEELCO be working on over the coming months?

B.T. :Following on from audio, our objective is to improve performance for video content. We are developing new corrective codes to restore data packets lost during transmission. Interesting research results are transferred to Expway, where the engineers design additional technological building blocks. Our goal, for an event like the Olympics for example, is to broadcast the event within a millisecond of it being filmed.
Our software is integrated in the equipment used to broadcast content and in the mobile devices receiving it. The Japanese market is especially promising: our solutions are already integrated on many mobile devices.

LEELCO is the result of many years of collaboration between Inria and Expway

Vincent Roca, one of the researchers in the Privatics team, has been working with the Expway SME since 2005, on improving the reliability of systems for delivering mass multimedia content to light mobile devices (smartphones and tablets). In 2014, the innovative solutions developed as a result of this collaboration received an award from the FIEEC, the federation which awards researchers whose technology projects have been transferred to industry through an SME or mid-cap.
LEELCO, an Inria Innovation Lab, was set up 2015 to pursue this collaboration. Its main aim is to improve the innovative solution and enable it to deal with another type of signal with even greater coverage than to date. This collaboration has led to the creation of two jobs, including a researcher who was taken on permanently after finishing their thesis.
