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.

Systems and methods for improved monitoring of content distribution are described herein. In some embodiments, control circuitry may transmit a video stream to a node, and compare a fingerprint of a first video frame transmitted from the node to reference fingerprints in database in order to determine a time offset between a transmission time of content to the node, and a transmission time of the content from the node. The control circuitry may then monitor a transmission from the node by transmitting a request, to the node, to generate a second fingerprint at a predetermined transmission time, the predetermined transmission time being a second transmission time of a second video frame to the node adjusted based on the time offset. In some embodiments, the control circuitry may also generate alerts based on determining that a node failed to properly retransmit content.

This application provides a non-terrestrial network (NTN) communication method and an apparatus. When performing a delay-sensitive communication service, UE may select a cell covered by a satellite since the UE cannot distinguish between a cell covered by a terrestrial base station and the cell covered by the satellite. A first network device determines cell type information of a cell covered by a second network device, where the cell type information indicates that the cell is a terrestrial network communication cell or a non-terrestrial network communication cell; and the first network device sends the cell type information to a third network device.

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.
