Abstract

In an example embodiment, there is described herein a methodology were the Forward Error Correction (FEC) data for a data stream is distributed into a plurality of FEC sub-streams. Subscribers to the data stream indicate which of the plurality of FEC sub-streams should be provided to them. The distribution of FEC sub-streams are limited to subscribed FEC sub-streams. FEC sub-streams with no subscribers are not forwarded beyond a distribution point such as an access point (AP).
