Combination of multiple regional beams and a wide-area beam provided by a satellite system
First Claim
1. A digital audio broadcasting satellite system coverage area comprising:
- a wide-area beam providing a wide-area coverage area; and
at least three beams, each of the at least three beams providing a coverage area overlapping the wide-area beam coverage area, wherein each of the three beams provides distinct media content to distinct regions within a system coverage area.

Abstract
A coverage area for a satellite digital audio broadcasting system is generated using a wide-area beam and at least three other beams. The other beams each have a coverage area that overlaps the coverage area of the wide-area beam. The beams may be generated by a plurality of satellites traveling in highly elliptical orbits. A frequency spectrum including four or more frequency blocks of approximately 1.5 MHz each may be used to transmit media content from the satellites on the beams. The multi-beam system can provide a content distribution blend tailored to specific regions while providing multi-regional content through out the coverage area. For example, the system provides a content distribution blend tailored to regional diversity of Europe through regional beams while providing European “country agnostic” or “supra-national” content to all users through the wide-area beam.

36. A digital audio broadcasting satellite system coverage area comprising:
-
a wide-area beam providing a wide-area coverage area; and
at least two beams having coverage areas smaller than the wide-area beam, wherein each of the at least three beams provides a coverage area overlapping the wide-area beam coverage area, the overlapping coverage area receiving media content from each of the beams providing the overlapping coverage area;
wherein each of the three beams provides distinct media content to distinct regions within the system coverage area;
wherein the distinct media content includes media content different than the media content provided by the wide-area beam; and
wherein the coverage area for each of the at least three beams overlaps the coverage area for at least one other beam of the at least three beams. - View Dependent Claims (37, 38, 39, 40, 41)
