1. A primary device (PD) configured to communicate with a companion device (CD), the primary device comprising:
a tuner configured to receive a broadcast signal including a signal frame;
a frequency deinterleaver configured to frequency deinterleave data in the signal frame based on a deinterleaving sequence that is generated by checking a range of a sequence and the sequence is generated based on a main sequence and a symbol offset;
a time deinterleaver configured to time deinterleave one or more FEC (Forward Error Correction) blocks in the frequency deinterleaved data in a memory based on position information for one or more virtual FEC blocks;
a controller configured to connect to the CD; and
a displayer configured to display service data in the one or more FEC blocks and supplementary information related to the service data.
