Claim:
1. A method of transmitting broadcast signals, the method including: formatting input streams into BB (Base Band) packets of PLPs (Physical Layer Pipes), wherein the formatting input streams further includes: encoding data of the PLPs; building at least one signal frame by mapping the encoded data of the PLPs; and modulating data in the built signal frame by an OFDM (Orthogonal Frequency Division Multiplexing) method and transmitting the broadcast signals having the modulated data, wherein the processing input packets further includes: determining that packet headers of a plurality of successive input packets in one input stream have a same value except for continuity counter fields and the continuity counter fields increase sequentially among the successive input packets, and deleting the packet headers of the successive input packets except for a packet header of first input packet in the successive input packets.
