Systematic Network Coding Based Reliable Real-Time Multimedia Streaming System

In this paper, we propose an implementation of a real-time multimedia streaming system that can simultaneously support a large number of clients. The proposed solution is based on systematic network coding that does not require feedback channels for acknowledgment or retransmission while it is resilient to packet erasures. Our experiment includes simultaneous full HD video transmission to 20 clients with 4 different types of mobile devices. The measured results confirm that the proposed system is the most robust against the packet losses compared to two conventional real-time streaming solutions.
