Abstract:
A system and method for adaptive error correction that optimizes bandwidth by taking into account expected, or predicted, interferences. The bandwidth used for error correction is applied judiciously based on the value of the content and the need to receive the content the first time it is broadcast. The present invention further applies local optimizations in the case of spot-beam satellite broadcasts. As each spot corresponds to a particular geographic region, different input parameters may be used, thereby maximizing efficiency.
