In the Laboratory for Multimedia and the Laboratory for Telecommunications, we were once again innovative during the information days organised by the Faculty of Electrical Engineering (University of Ljubljana, Slovenia), for everyone interested in studying at our faculty.
In cooperation between both laboratories and with the support of Kontron, Huawei and Telekom Slovenije, we prepared a wireless transmission of AV-over-IP signal in real time using our own 5G SA NPN (standalone non-public network), including usage in the live broadcast via the Radio-Television of Slovenia outside broadcasting truck. We demonstrated the solution by using it on the steadycam system for stabilizing mobile cameras, on which we also checked the operation of the network, transmission and the system as a whole via a mobile phone.
Such solutions offer many practical application options – e.g. wireless cameras for the purpose of ensuring mobility and different views in live TV broadcasts (on steadycam systems, drones, motorbikes, etc.) or performing live TV broadcasts remotely or in the cloud (source signal equipment is placed at the production location, while the location of the other equipment is arbitrary and can be permanently placed somewhere).
This time we used the AV-over-IP protocol NDI (full NDI, up to 1080p50, without bridge), but of course, based on our work and research to date, we will at least look towards using the AV-over-IP protocol SMPTE 2110, also in combination with JPEG XS compression technology, and towards the AV-over-IP protocol Dante (Audinate).
We look forward to continuing research in this area, as the next steps offer many opportunities for optimization in the selection and configuration of equipment included in such solutions, as well as for performing and analyzing measurements and comparing performance with alternative solutions.
