Abstract
A broadcast receiving system capable of receiving mobile broadcast data and a method for processing broadcast signals are disclosed. The broadcast receiving system includes a first receiving unit, a second receiving unit, a known sequence detector, a equalizer, and a display unit. The first receiving unit receives a first broadcast signal including first mobile broadcast service data and first main broadcast service data. The second receiving unit receives a second broadcast signal including second mobile broadcast service data and second main broadcast service data. The known sequence detector detects at least one of known data included in the received first broadcast signal and known data included in the received second broadcast signal. The channel equalizer uses the detected known data, thereby channel-equalizing the received first and second mobile broadcast service data corresponding to the detected known data. The display unit provides any one of first video data and second video data included in the channel-equalized first and second mobile broadcast service data to a user.

13. A method of transmitting broadcast signals, the method comprising:
-
FEC encoding mobile data by adding parity bits with a first code rate; interleaving the FEC encoded mobile data; mapping the interleaved mobile data into a data unit that includes a first region and a second region, the first region including signaling information of the mobile data; and transmitting the broadcast signals including the data unit, wherein the data unit is multiplexed with a data unit of main data during a specific time period, wherein the signaling information includes information of a group to which the data unit belongs, wherein a plurality of groups are allocated in a signal frame, and wherein each of the plurality of groups carries different broadcast service. - View Dependent Claims (14, 15, 16, 17, 18, 19)
