Transmitting system and method of processing digital broadcast signal in transmitting system
First Claim
1. A method for transmitting a broadcast signal in a transmitter, the method comprising;
- multiplexing a specified number of mobile data packets, a 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, the slot during which the main data and a data group including the mobile data are transmitted;
wherein the data group includes a plurality of regions, the plurality of regions including data blocks, each data block including a plurality of data segments, wherein a first and second regions include data included in a primary ensemble of the mobile data, known data sequences and signaling bytes for signaling the mobile data, a third, fourth and fifth regions include data included in a secondary ensemble of the mobile data, and the fifth region includes the first scalable number of mobile data packets,wherein the data group has a data area for RS parities and MPEG headers, and the data area is allocated to mobile data when the first scalable number is equal to 38.
