METHOD FOR GROUPING STATIONS TOGETHER IN ORDER TO OPTIMIZE THE BROADCAST OF A BROADCAST/MULTICAST STREAM

摘要

The present invention relates to a method for transmitting at least one data stream from a station to N receiving stations, wherein N=2. The stations, which are connected together via links, belong to a single logic network and, during transmission, implement multi-carrier modulation, each link between the station and one of the N receiving stations being associated with a table containing orders of constellations associated with the sub-carriers, respectively, said orders being determined according to one or more quality criteria of the link, said method consisting of: grouping the N stations into K groups, wherein K=1, according to a similarity criterion between tables, and determining a common table per group; transmitting, via the station and to the K groups, respectively, a stream in the form of K streams by distributing the stream data over the sub-carriers according to the common table of the group.
