APPARATUS FOR TRANSMITTING BROADCAST SIGNALS, APPARATUS FOR RECEIVING BROADCAST SIGNALS, METHOD FOR TRANSMITTING BROADCAST SIGNALS AND METHOD FOR RECEIVING BROADCAST SIGNALS

摘要

The present invention provides a method of transmitting broadcast signals, the method including, encoding service data, building at least one signal frame by mapping the encoded service data, modulating data in the built at least one signal frame by an Orthogonal Frequency Division Multiplexing, OFDM, scheme and transmitting the broadcast signals having the modulated data.
