Abstract
Systems, algorithms and methods for reclaiming unused portions of a satellite broadcast service's bandwidth for new services, utilizing higher performance coding techniques to yield better throughput, are presented. Reclamation of bandwidth can be achieved in a way that is invisible to a legacy receiver, and that does not interfere with its reception of a legacy signal. New data may be transmitted within a legacy transmission frame, for example within its cluster structure, using the same modulation and synchronization as used for the legacy data. In other embodiments, one or more clusters or subdivisions with only new data may be transmitted, using the same or different modulation and synchronization as the legacy data clusters, but now employing a higher performing FEC and data interleaving structure on those clusters which contain only new data to yield an increase in available throughput.
