Raptor Codes in practice: Implementing a server for live TV streaming

Speaker: Dr. Giovanni Cangiani , ALGO, EPFL


Internet television (IPTV) is a rapidly growing way of wasting internet bandw idth. Internet is global and makes it easy to implement a true Video on Demand ( VoD) system. On the other hand, the most used transport protocol over the intern et (TCP) is not well suited for large scale, long distance and good quality vide o streaming. A much better alternative is represented by standard UDP in conjunc tion with a robust forward error correction scheme. In this talk, I will describ e in some details the implementation of a prototype system that is being develop ed at ALGO for streaming live television over the internet using UDP and systema tic Raptor as protection layer.
