摘要:
The present disclosure is directed to a system and method of correcting video data errors. In a particular embodiment, the method includes receiving a stream of data packets at a re-generator of an Internet Protocol (IP) video transport stream. The stream of data packets includes a plurality of IP media packets and a plurality of forward error correction (FEC) packets. The method also includes determining an error profile of an error within the plurality of IP media packets. The method includes identifying one of the plurality of FEC packets, where the identified FEC packet is associated with an error correction code corresponding to the error profile. The method also includes selecting an inverse FEC function from a plurality of inverse FEC functions. The selected inverse FEC function corresponds to the identified FEC packet.
