Systems and methods for combining 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 uplink to a satellite, receiving 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, and passing respective original data steams to, e.g., one or more DVB-T modulators for broadcast into a single frequency network.
