Abstract : This work focuses on the provision of broadcast services where contents of any kinds must be transmitted in an efficient manner to a set of receivers. Several problems arise: - the robustness in front of transmission issues, no matter whether it consists of errors (bit inversion) or erasures (of packets); - the efficiency of the provided service, in terms of error and/or erasure recovery performance and low algorithmic complexity; - the fulfilment of the potential real-time constraints of some contents; - and finally the scalability of the service when the number of receivers significantly increases. The problem space is rather large and we "limit ourself" to two essential components, namely: - the application-level correction codes, or AL-FEC,for the erasure channel and without which the efficiency of the service would be largely compromised, and - the transport protocols that define the rules for the exchange of information between the source(s) and the destination(s), and provide the required reliability. Throughout this document, we detail these two axes and position our contributions and their actual usage in the current situation.
