11. The method of claim 1 , wherein the selected modcode is the same for each packet of the linear media channel segment.
12. The method of claim 1 , wherein the plurality of crafts are within a service area of the shared communication link.
13. The method of claim 1 , further comprising:
transmitting, with the linear media channel segment, the indication of the selected modcode.
14. A system for providing communications via a communication link that is shared for a plurality of crafts, comprising:
