Abstract
A system and method for increasing reliability for media data distribution using an unreliable protocol within a network of devices is provided. A preemptive packet recovery (PPR) module is provided within a receiver to organize any correctly received payload packets and recover any missing payload packets using a plurality of forward error correction packets. The forward error correction packets include redundant payload data corresponding to the payload packets. If the PPR module is not able to recover a missing payload packet, the PPR module sends a Negative Acknowledgment (NACK) to the provider requesting that the provider resend the missing packet. The system relies on the recovery logic enabled by a packet reconstruction module to recover any missing packets and only requests the resending of missing packets when packets are not recoverable, thus maintaining the increased speed of UDP while increasing the reliability of the data being sent and received.
