Abstract
A method and apparatus for receiving broadcast signals are discussed. The method includes receiving the broadcast signals; demodulating the received broadcast signals by an Orthogonal Frequency Division Multiplex (OFDM) scheme; obtaining broadcast data from a signal frame in the demodulated broadcast signals, wherein the broadcast data includes video data or audio data, and the broadcast data is carried by only a Data Pipe (DP); decoding the broadcast data; and output-processing the decoded broadcast data to output a data packet, wherein the data packet includes a Transport Stream (TS) packet, wherein a header of the data packet includes first information indicating whether a header deletion is performed in the TS packet, wherein the header of the data packet further includes second information indicating whether a null packet deletion is performed, and wherein when the second information is not a zero value, the null packet is deleted prior to the data packet.
