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).

Abstract translation: 在示例实施例中，这里描述了一种方法，即将数据流的前向纠错（FEC）数据分发到多个FEC子流中。 数据流的订户指示应向其提供多个FEC子流中的哪一个。 FEC子流的分布限于订阅的FEC子流。 没有订户的FEC子流不被转发到诸如接入点（AP）的分发点之外。
