METHOD AND SYSTEM FOR BROADCASTING DATA

摘要

The invention relates to a data broadcast, implemented in at least a first transmitter (111 to 113,121,122). In order to optimize resources, the broadcast comprises steps consisting in: constructing OFDM symbols, each symbol comprising first data and second data associated respectively with first (10) and second (11, 12) broadcast areas (10), the first area covering at least part of the second area, a first set of sub-carriers carrying information representative of the first data in each OFDM symbol, a second set of sub-carriers carrying information representative of the second data in each OFDM symbol, the first and second sets of sub-carriers being disjointed, and broadcasting of OFDM symbols intended for a plurality of receivers.
