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.

Abstract: A digital television transmitting system includes a frame encoder, a block processor, a group formatter, and a multiplexer. The frame encoder forms an enhanced data frame and encodes the data frame for error correction and for error detection. The block processor further encodes the encoded data frame at a rate of 1/2 or 1/4, and the group formatter divides the encoded data frame into a plurality of enhanced data blocks and maps the divided data blocks into a plurality of enhanced data groups, respectively. The multiplexer multiplexes the enhanced data groups with main data.
