Embodiments facilitating mixed service use of bonded satellite transponders in communication systems are provided. An apparatus comprises a first multiplexer configured to receive first content from first channels of a first type of channel, a second multiplexer configured to receive second content from second channels of a second type of channel, and a transport stream processor (TSP). The TSP can be configured to output the received first content and the second content to modulators respectively associated with different channels for transmission of the first type of channel and the second type of channel, wherein the different channels are transmitted to a bonded satellite transponders, which transmits to a receiver. In some embodiments, the apparatus can comprise a multiplexer aggregator coupled between the TSP and the first multiplexer and the second multiplexer. The first content can be high bit-rate information and the second content can be lower bit-rate information.
