| 1. A method for providing broadcast services in an Orthogonal Frequency Division Multiplexing (OFDM) system with a transmission
structure in which one slot includes at least two symbols and each symbol includes a plurality of subcarriers, comprising
the steps of:
multiplexing packets of different broadcast service into one slot, and transmitting the multiplexed packets; and
transmitting overhead information related to the multiplexed packets,
wherein the overhead information includes indicating information about whether the packets of the different broadcast service
are multiplexed, first mapping information about symbol positions of the multiplexed packets when the packets of the different
broadcast service are multiplexed, and second mapping information about subcarrier groups of the multiplexed packets when
the packets of the different broadcast service are multiplexed.
