Service group discovery

A subscriber device for discovering a service group, comprising:

• a memory that stores instructions;
• and
• a processor, coupled to the memory, configured to execute the instructions, the instructions, when executed by the processor, configuring the processor to:
• receive a configuration file that stores a listing of mappings, wherein each association of the listing of mappings maps network characteristics to a service group identification (SGID), a list of transport stream IDs (TSIDs), and a list of radio frequencies (RFs);
• select one or more associations related to a network characteristic from the listing of mappings, wherein the network characteristic includes a plant ID identifying a physical network infrastructure for carrying transport streams between a plurality of subscriber devices and a headend system and a network ID specifying a portion of the physical network infrastructure associated with the subscriber device;
• tune to an RF selected from the list of RFs within a selected association to identify a TSID of the tuned RF;
• verify whether the identified TSID matches a TSID from a list of TSIDs associated with the selected association;
• and
• in response to the verify, determine that the SGID in the selected association identifies the service group for the subscriber device.

A non-transitory machine-readable medium having instructions stored thereon that, when executed by one or more processors of a subscriber device, causes the one or more processors to perform operations comprising:

• receiving a configuration file that stores a listing of mappings, wherein each association of the listing of mappings maps network characteristics to a service group identification (SGID), a list of transport stream IDs (TSIDs), and a list of radio frequencies (RFs);
• selecting one or more associations related to a network characteristic from the listing of mappings, wherein the network characteristic includes a plant ID identifying a physical network infrastructure for carrying transport streams between the plurality of subscriber devices and a headend system and a network ID specifying a portion of the physical network infrastructure associated with the subscriber device;
• tuning to an RF selected from the list of RFs associated with a selected association to identify a TSID of the tuned RF;
• verifying whether the identified TSID matches a TSID from the list of TSIDs within the selected association;
• and
• in response to the verifying, determining that the SGID in the selected association identifies the service group for the subscriber device.
