Claim:
1. A method for transmitting broadcast signals, the method comprising: encoding service data; mapping the encoded service data; time interleaving the mapped service data, wherein the time interleaving is performed depending on a number of physical paths for the service data, wherein the number of the physical paths is a multiple, wherein the time interleaving for multiple physical paths includes: block interleaving at least one TI (Time Interleaving) block of the mapped service data in each physical path; and building the at least one signal frame including the time interleaved service data; modulating data in the built at least one signal frame by an OFDM (Orthogonal Frequency Division Multiplex) scheme; and transmitting the broadcast signals having the modulated data.
