<p>The present invention relates to an apparatus for receiving a broadcast signal and a method for transmitting and receiving a broadcast signal. A method for receiving a broadcast signal according to an embodiment of the present invention comprises the steps of: receiving a broadcast signal, wherein the broadcast signal is identified by a transport stream identification field, and includes a cell information table (CIT), and the CIT includes a cell identifier field to identify a cell according to a transmission area where the broadcast signal is transmitted; demodulating the received broadcast signal; extracting the CIT from the demodulated broadcast signal, wherein the CIT additionally includes a service identification field and a cell number field, a service ID respectively identifies broadcast services in the broadcast signal, and the cell number field indicates a number of adjacent cells according to a transmission area where a broadcast service identical or similar to a broadcast service identified by the service identification is transmitted; acquiring the broadcast service using the extracted CIT; and decoding the acquired broadcast service. [Reference numerals] (AA) Start; (BB) End; (S10) Multiplex broadcast data with program table information, to which identifier information of a cell that is a propagation area of a broadcast signal is set, and output a modulated broadcast signal; (S20) Transmit the broadcast signal including the identifier information of the cell; (S30) Receive the broadcast signal including the identifier information of the cell that is the propagation area of the broadcast signal; (S40) Demodulate the received broadcast signal, parse the program table information from the demodulated broadcast signal, and obtain the identifier information of the cell</p> |
