Abstract:
1. A method for transmitting a digital broadcasting signal in a transmitter, the method comprising; FEC (Forward Error Correction) encoding mobile data to build one or two data frames of the mobile data; Dividing the data frames into a plurality of data portions; Forming a data group including the mobile data in one of the data portions; Forming a fixed number of mobile data packets and a first scalable number of mobile data packets including the mobile data in the data group; Multiplexing the fixed number of mobile data packets, the first scalable number of mobile data packets and a second scalable number of main data packets; Interleaving mobile data in the mobile data packets and main data in the main data packets; Transmitting the interleaved mobile and main data during a slot; Wherein the data group includes a plurality of blocks, the data group includes a first region including central blocks in the data group, a second regions including blocks being concentric about the first region, a third region including blocks being concentric about the first and second regions and a fourth region including blocks being concentric about the first, second and third regions, Wherein the data group further includes a fifth region in which a plurality of blocks is included, wherein the plurality of blocks includes the first scalable number of mobile data packets.
