Abstract:
1. A receiving system comprising: a module configured to receive location information identifying a current location of the receiving system; a tuner configured to receive a broadcasting signal comprising mobile service data, known data sequences, segment synchronization data, field synchronization data and a cell information table including cell information, wherein the cell information includes cell location information for defining a location of each cell and transport stream identification information for identifying the broadcasting signal carrying the mobile service data; a demodulator configured to demodulate the received broadcasting signal; a channel equalizer configured to compensate channel distortion of the demodulated broadcasting signal based on at least one of the known data sequences; a first decoder configured to perform cyclic redundancy check (CRC) decoding and Reed-Solomon (RS) decoding on an RS frame including mobile service data in the channel distortion compensated broadcasting signal to correct at least one error in the RS frame; a second decoder configured to extract the cell information from the error-corrected RS frame; and a controller configured to control the tuner based on the extracted cell information to facilitate continuous watching by a user of a same mobile service when traveling from a coverage area of one transmitter to a coverage area of another transmitter.
