Systems and methods are disclosed herein for correcting errors. In one embodiment, among others, a method comprises receiving a plurality of error indications from a plurality of respective receivers. The receivers are configured to receive a data stream of packets transmitted within a multicast channel. Each error indication indicates which ones of a number of the packets were not received. The method further comprises analyzing the error indications to determine a first set of receivers to which forward error correction (FEC) code is transmitted and a second set of receivers to which unicast data is transmitted.
