研究领域

In Multimedia and Broadcast Networks Group, we will develop more efficient and intelligent systems for the management of communication networks through the seamless integration of Internet and broadcast networks, and faster, flexible, more efficient radio transmission systems, through synergies between artificial intelligence, media and radio signal processing, for operating in heterogeneous and changing environments. We will also develop flexible, harmonized security systems for services and media to provide pervasive and trusted network and service infrastructures and international access to services and media
