Abstract
A transmitting system, a receiving system, a method of processing broadcast signals and a method of receiving broadcast signals are disclosed. The method of transmitting a broadcast signal includes forming a data group including a specified number of mobile data packets and a scalable number of mobile data packets, transmitting a broadcast signal including the data group during slot. The data group includes signaling data includes a protocol version field indicating whether or not the scalable number of mobile data packets exist in the slot. Also, the data group includes known data sequences inserted a predetermined area in the data group. The method of receiving a broadcast signal includes receiving a broadcast signal including the data group, detecting the known data sequence from the predetermined area in the data group, for equalizing channel of mobile data in the data group and decoding the signaling information in the data group.
