This PhD project is titled: Object oriented edge-casting using semantic encoding and is part of WP5 Digital infrastructure.
Media distribution is undergoing radical transformations from dedicated infrastructures (e.g. DAB, FM and DVB-T) to IP based distribution infrastructures, and heterogeneous networks and storage environments based on Cloud based services, CDNs and Edge Computing. This complex chain of delivery has negative implications for the robustness needed for delivery of media content e.g. in events of crisis and emergency.
On the other side, there is a high degree of synergy and convergence between the dedicated media platforms, including over-the-top and the ongoing development of 5G and 6G. With new network structures, also conditions for content creation changes; it can be assembled ‘on the fly’ allowing for a highly granular and personalised media experience, as formulated in SMPTE ST 2110 suite of standards for video, audio and data over IP. This research asses the implications for public interest media of these fundamental changes and the implications for the robustness of the media infrastructure.
The position addresses the implications for the robustness of media delivery infrastructures in the shift from the robust architecture of radio-TV transmitters and receivers to the far more complex and fragile structure of ‘over-the-top’ (IP-based) media delivery.
The project will model optimal architectures of IP based media for efficient utilization of the underlying resources while securing robustness in delivery.
The position requires relocation to Denmark as the candidate will be enrolled in the PhD programme of Aalborg University. The project is conducted under the supervision of Reza Tadayoni, Associate Professor at Aalborg University, and Helle Sjøvaag, Professor at the University of Stavanger. It will involve close collaboration with other Doctoral Candidates in the RePIM doctoral Network Project, and an academic secondment of approximately 2 months at the University of Stavanger in Norway. The candidate will also carry out 3-month internship at the European Broadcasting Union (EBU) in Geneva.
