Abstract
The present invention relates to a method of transmitting and a method of receiving signals and corresponding apparatus. One aspect of the present invention relates to an efficient layer 1 (L1) processing method for a transmitter and a receiver using data slices.
Claims15
A transmitter for transmitting broadcasting data to a receiver, the transmitter comprising:
- a FEC (Forward Error Correction) encoder configured to FEC encode Layer 1 signaling data;
- a bit interleaver configured to bit interleave the FEC-encoded Layer 1 signaling data;
- a QAM mapper configured to demultiplex the bit interleaved Layer 1 signaling data into cell words and to map the cell words to constellation values corresponding to Layer 1 signaling data;
- a time interleaver configured to time-interleave the mapped constellation values corresponding to Layer 1 signaling data;
- an inserter configured to insert a Layer 1 header into the time-interleaved constellation values corresponding to Layer 1 signaling data;
- a repetition means configured to repeat the constellation values corresponding to Layer 1 signaling data and the Layer 1 header;
- and
- a frequency interleaver configured to frequency interleave the repeated constellation values corresponding to Layer 1 signaling data and Layer 1 header.
