Abstract:
1. A receiving system, comprising: a signal receiving unit, when a parade change command ordering parade change from a first parade to a second parade is generated, receiving a broadcast signal including data groups of the second parade starting from a generation point of the parade change command, while receiving the broadcast signal including a transmission frame transmitting the first and second parades; a signaling decoder decoding signaling information included in the data groups and outputting RS frame-related information; a block decoder performing turbo-decoding in block units on data of a portion included in the data groups; and an RS frame decoder inserting null data in data positions of a portion included in non-received data group within an RS frame of the second parade, while configuring the RS frame of the second parade by collecting data of the turbo-decoded portions based upon the RS frame-related information, performing CRC-decoding by indicating the existence of errors on CRC error flags of each row including the null data within the RS frame, and performing RS-decoding on the CRC-decoded RS frame.
