METHODS AND SYSTEMS FOR PROVIDING DIFFERENT DATA LOSS PROTECTION

摘要

This invention relates to methods and apparatus for partitioning a data word into a protected region and an unprotected region in the link layer, forward error correction of a DVB-H module to provide unequal error protection of frames during forward error correction of the frames. IP-datagrams are encapsulated for coding after a pre-loading stage is initiated so that the reliability and importance of data in data frames corresponding to the IP-datagrams can be determined. Unequal error protection is further achieved by padding zeros in the unprotected region.
