Abstract

See full text

A method for transmitting broadcast signals encodes service data corresponding to each of a plurality of physical paths and time interleaves the encoded service data by using each Time Interleaving (TI) block in an interleaving frame. In the time interleaving, each TI block includes a number of actual Forward Error Correction (FEC) blocks having the encoded service data, and further includes a number of virtual FEC blocks equal to a difference between the number of actual FEC blocks of each TI block and a maximum number of actual FEC blocks. The time interleaving is performed by acquiring a cell position by using a row index, a column index and a twisting parameter, and when the acquired cell position is corresponding to a virtual cell in the number of virtual FEC blocks, the acquired cell position is skipped during a reading operation of the time interleaving.
