Hierarchical broadcast transmission via multiple transmitters
First Claim
1. A method of controlling a wireless broadcast transmission of media data via multiple transmitter sites into a broadcast area with different transmitter inter-site distances, wherein the method comprises the steps of:
- determining a region of large transmitter inter-site distance and a region of small transmitter inter-site distance based on a distance threshold between the multiple transmitter sites in the broadcast area;
initiating a first transmission of the media data to a first transmitter site in the region of large transmitter inter-site distance; and
initiating a second transmission of the media data of different quality to a second transmitter site in the region of small transmitter inter-site distance.

Abstract
A technique for controlling a wireless broadcast transmission of media data via multiple transmitter sites into a broadcast area with different inter-site distances is proposed. The broadcast area comprises a region of large inter-site distance (ISD) and a region of small inter-site distance. The technique provides for a high spectral efficiency in regions of small ISD and at the same time for an acceptable reception quality in regions of large ISD. A first transmission is initiated into the broadcast area, wherein the first transmission is adapted for reception in a first of the regions. A second transmission is initiated into a second of the regions, the second transmission being adapted for reception in the second region.
