17. A method for transmitting broadcast signals, the method comprising:
-
generating service components for a first broadcast service and first signaling information providing information for acquisition of the service components for the first broadcast service, wherein the first signaling information includes a first service identifier(ID) for identifying the first broadcast service and a second service ID being globally unique ID; encoding the service components and the first signaling information; building at least one signal frame including the encoded service components and the encoded first signaling information; modulating data in the built at least one signal frame by OFDM (Orthogonal Frequency Division Multiplex) scheme; and transmitting broadcast signals including the modulated data through a broadcast path. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
