A system, apparatus, and method provide messaging, between a headend system and a set top box. A distributor determines and provides an assigned communication identifier and an assigned server host address, that correspond to one of one or more first servers, to each of one or more set top box clients. The first servers maintain a persistent connection with the set top box clients and provide messaging, presence, and routing features via the persistent connection. A gateway service provides a gateway for one or more headend servers to communicate with the set top box clients through the first servers. A server controller provides administrative graphical user interfaces for operators to monitor and control health checks, configuration changes, and collect statistics for the distributor, first servers, and the gateway service.

Method and system for conveying a plurality of component signals transmitted from a multi-waveform transmitter to a ground hub having or coupled to an equal plurality of receivers as a combined signal in a common frequency band. For each of the component signals respective adjusted signals are generated by adjusting at least one inherent characteristic of the respective component signals based on waveform-specific constraints so as to allow discrimination of the adjusted signals by a respective one of the receivers based solely on the at least one inherent characteristic without requiring additional signal information and without requiring encoding of the component signals by the transmitter. The adjusted signals are combined in a common frequency band to form a combined signal. and transmitted to the ground hub.
