Claim Text:
1. A method for transmitting broadcast signals, the method comprising: input processing Transport Stream (TS) packets or Internet Protocol (IP) packets or Generic Stream Encapsulation (GSE) streams to output data of a plurality of Physical Layer Pipes (PLPs); encoding signaling information for signaling the plurality of PLPs; encoding data of each of the plurality of PLPs, wherein the each of the plurality of PLPs carries at least one of a base layer and an enhancement layer of services; Quadrature Amplitude Modulation (QAM) mapping the encoded data of each of the plurality of PLPs; Multi-Input Multi-Output (MIMO) processing the QAM mapped data; time interleaving the MIMO processed data; building first and second signal frames by mapping the time-interleaved data, wherein each of the first and second signal frames includes a preamble and data symbols, wherein the preamble includes the signaling information and the data symbols include the plurality of PLPs, and wherein a PLP of the plurality of PLPs carries at least one table including bootstrap information and Electronic Service Guide (ESG) signaling information; frequency interleaving data in the first and second signal frames; and modulating the frequency-interleaved data by an Orthogonal Frequency Division Multiplexing (OFDM) method and transmitting first and second broadcast signals having the modulated data.
