Abstract

Convergence has become a key idea in communications over the past few years and IP has become the key ‘convergence layer’. GSE (Generic Stream Encapsulation) enables the carriage of IP packets directly over DVB-S2 networks in a very efficient way, and it is considered to be used in the future access encapsulation. Thinking that these future services will be all-IP, this paper is intended to explain how the header of the BBFRAME (Base-Band Frame) of the DVB-S2 can be optimized until be completely removed in future broadcast satellite networks which will use IP/GSE/DVB-S2 only stack. This reduction is intended to separate the physical layer and link layer functionalities provided both by DVB-S2 and to simplify and ease the understanding of the DVB-S2 protocol.
