Patent ID: 7843947

Claim:
A method for providing unequal error protection to datagrams in a DVB-H transmission system, comprising: for each time-sliced burst in a media stream processed by a processor: grouping all datagrams for the time-sliced burst based upon respective priority levels; and creating a MPE-FEC matrix for each group of datagrams based upon priority level; computing the number of RSDT columns for each of the MPE-FEC matrices, wherein the number of RSDT columns for each of the MPE-FEC matrices is chosen such that the average service bit rate does not exceed the maximum expected average service bit rate, and the RSDT protection for MPE-FEC matrices with lower priority does not exceed the RSDT protection for MPE-FEC matrices with higher priority; and encapsulating an application data table and RSDT of all MPE-FEC matrices in the burst into MPE-FEC sections.
