System and method for providing unequal error protection to priority labeled datagrams in a DVB-H transmission system

摘要

An improved system and method for transmitting a multiplexed service stream over an error prone DVB-H channel. Media IP packets are priority labeled. For each time slice burst, the IP packets are grouped based upon the priority labels. MPE-FEC matrices are made for the different priority labels in each time slice burst. RSDT columns are computed such that the average service bit rate does not overshoot the maximum allowed service bit rate, and the protection increases with priority. The ADT and RSDT of the MPE-FEC matrices are then encapsulated into MPE-FEC sections.
