In wireless networks, the quality of the media delivered to the user by real-time multimedia applications can be enhanced if corrupted packets are delivered to the application layer instead of being discarded at lower levels. Those erroneous packets are efficiently supported with the new error-resilient multimedia codecs and with UDP-lite. The Multi Protocol Header Protection (MPHP) is an efficient means to enable this thanks to an FEC mechanism which protects all protocol headers involved in the data transfer. MPHP improves the throughput by several orders of magnitude compared with conventional protocol stack. We show this efficiency in the specific context of satellite networks.
