ABSTRACT:
The present disclosure is directed to a system and method of correcting video data errors. In a particular embodiment, the method includes receiving a plurality of Internet Protocol (IP) video data packets at a generator of a video acquisition system. The method also includes calculating a first error correction code corresponding to a first error profile and generating a first forward error correction (FEC) packet to produce the first error correction code. The method also includes calculating a second error correction code corresponding to a second error profile and generating a second FEC packet to produce the second error correction code. Further, the method includes transmitting a stream of data packets including the plurality of IP video data packets, the first FEC packet and the second FEC packet, to a re-generator of an Internet Protocol video transport system, where an arbitrator of the re-generator identifies an error in the plurality of IP video data packets and selects one of a plurality of inverse FEC functions to correct the error.
