The level of erasure protection can be explicitly adapted to the importance of the respective parts in the source stream, thus allowing a graceful degradation of application quality with increasing packet loss rate on the network. Hence, this type of unequal erasure protection (UXP) schemes is intended to cope with the rapidly varying channel conditions on wireless access links to the Internet backbone. Furthermore, protection of non-progressive multimedia streams is ensured, since equal erasure protection (EXP) represents a subset of generic UXP. By applying interleaving and RS codes a payload format is defined, which can be easily integrated into the existing framework for RTP.}, }
