To send forward error correction (FEC) data to clients, you must modify the announcement file so that the client connection URL requests the data. The following example announcement file uses the URL modifier WMFecSpan to define how many data packets the forward error correction data will encompass and the modifier WMFecPktsPerSpan to define how many error correction packets are sent with the data packets. In this example, the parameters specify that the server will send one FEC packed for every four data packets.
