Method and system for delivering real-time content using broadcasting and unicasting

A system for broadcasting comprising:

• a plurality of devices;
• and
• a content distribution system in communication with the plurality of devices programmed to determine an identified content for a broadcast to a broadcast group comprising the plurality of devices in a service area;
• the content distribution system programmed to determine a priority for the identified content for each of the plurality of devices,
• the content distribution system programmed to determine radio conditions for each of the plurality of devices in the service area;
• the content distribution system programmed to determine an available network capacity of a network for broadcasting in the service area;
• the content distribution system programmed to determine a target spectral efficiency for the broadcast to achieve a performance target for a maximized population coverage across the plurality of devices, said target spectral efficiency based on the priority for the identified content for each of the plurality of devices, the radio conditions, the available network capacity and a modulation scheme and a coding scheme for the broadcast;
• the content distribution system programmed to broadcast the identified content to the plurality of devices in the service area based on the spectral efficiency for the broadcast;
• the content distribution system programmed to receive performance feedback data from each of the plurality of devices;
• the content distribution system programmed adjust the target spectral efficiency to form an adjusted spectral efficiency based upon the performance feedback data;
• and
• the content distribution system programmed to broadcast the identified content to the plurality of devices based on the adjusted spectral efficiency.
