Abstract
The disclosed embodiments relate to a system and method for grouping program identifiers into multimast groups. More specifically, there is provided a method comprising receiving a request for satellite services from a requester device, wherein the request includes at least one program identifier, creating a second group of program identifiers, comparing the requested program identifier with a first group of previously requested program identifiers stored on a satellite service providing device, and moving the matching program identifier from the first group of program identifiers to the second group of program identifiers if the requested program identifier matches one of the program identifiers in the first group of program identifiers, wherein a multicast of the second group of program identifiers is adapted to be shared by the requester device and another device.
