LiveU’s technology enables live, wireless video transmission from any location around the world with easy-to-use professional equipment. LiveU offers a complete range of devices for live, mobile video transmission anytime, anywhere. To manage video streams coming from these devices, LiveU developed software platform which includes MultiMedia Hub (MMH) as its core part. MMH is the software component that reconstructs multiple incoming LiveU streams. MMH handles both encoded and raw data. The data are transmitting to MMH with LiveU’s Reliable Transport protocol (LRT™) which enables reliable, low delay live video streaming over non-guaranteed IP networks and ensures reliable transport over the most unreliable of networks, including cellular networks.
The input data (video and audio streams) are pre-processing by using microservice called Collector which sends this data to Multimedia Distributer. Collector outputs the RTP packets. The Multimedia Distributer conveys the streams to other microservices. One of them is Multimedia Transformer. This microservice allows to encode data in different formats before their further transmission via Storage Device Interface, Network Device Interface. The streams are to be distributed as it shown at the picture.
The MMH is an integral part of the PrEstoCloud Media Use Case (the deliverables for further reading are available at http://prestocloud-project.eu/deliverables/). The concretisation of the MMH processes, which can be useful for evaluation of PrEstoCloud services, in particular, Network Virtualization and Security Enforcement, is in progress now.
