SYSTEM AND METHOD FOR PROVIDING UNEQUAL ERROR PROTECTION TO PRIORITY LABELED DATAGRAMS IN A DVB-H TRANSMISSION SYSTEM

摘要

A kind of improvement system and method, for sending multiplex stream DVB-H services in the channel for being easy to appear mistake. Media IP packets are the labels of priority. It happens suddenly for each timeslice, which is grouped the label according to priority. MPE-FEC matrixes happen suddenly to the label of different priorities in each timeslice. It calculates RSDT to arrange so that average service bit rate is no more than maximum allowable service bit rate, protection has priority. Then the RSDT of the ADT and MPE-FEC matrixes is encapsulated into MPE-FEC sections.
