Abstract
There are described apparatus and methods for adaptive forward error correction (FEC), one use being for video streaming over a wireless network. The apparatus includes an FEC encoder and an adaptive FEC device. The FEC encoder is for encoding k packets of source data into n packets, where n>k, and the n packets include redundant packets. The adaptive FEC device is for adaptively determining a number of the redundant packets to transmit with the encoded k packets, based upon receiving one or more feedback messages. The one or more feedback messages indicate a condition of the wireless network over which the encoded video is to be transmitted.
