ABSTRACT:
Systems and methods for handling packet errors in a system that combines a plurality of transport streams into a single transport stream for transmission to, e.g., a single frequency network via a satellite. Embodiments provide receiving a plurality of original, e.g., MPEG-compliant, data streams, where each original data stream has its own timing information, combining the plurality of original data streams into a single combined data stream which is also, e.g., MPEG compliant, modulating the single combined data stream for, e.g., uplink to a satellite, receiving, e.g., a downlink transmission from the satellite, where the downlink transmission includes the single combined data stream, de-combining the single combined data stream into the plurality of original data streams, determining whether any packets have been lost and compensating for such lost packets, and passing respective original data steams to one or more DVB-T modulators for broadcast into, e.g., a single frequency network.
