Abstract
A method and an apparatus for transmitting broadcast signals thereof are disclosed. The method for transmitting broadcast signals includes processing input streams into BB frames in PLPs; 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 OFDM method and transmitting the broadcast signals having the modulated data, wherein at least one of the BB frames includes a stuffing field and a first indicator describing whether the stuffing field is included in the BB frame.
Claims24
A method of transmitting broadcast signals, the method including:
- processing input streams into BB (Base Band) frames in PLPs (Physical Layer Pipes);
- 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 OFDM (Orthogonal Frequency Division Multiplexing) method and transmitting the broadcast signals having the modulated data,
- wherein at least one of the BB frames includes a stuffing field and a first indicator describing whether the stuffing field is included in the BB frame.
A method of receiving broadcast signals, the method including:
- receiving the broadcast signals having at least one signal frame and demodulating data in the at least one signal frame by OFDM (Orthogonal Frequency Division Multiplexing) method;
- parsing the at least one signal frame by demapping data of PLPs (Physical Layer Pipes);
- decoding the data of the PLPs;
- and
- processing BB (Base Band) frames in the PLPs to output streams,
