The structure and length of such a transmission frame are determined according to a transmission mode. The broadcast signal transmitting apparatus 100 provides a transmission mode regardless of the type of data transmitted through the FIC and the MSC using the FIB and the CIF. That is, data is transmitted in FIB or CIF units regardless of the transmission mode. However, only the number of input FIB and CIF is set differently according to the transmission mode.

Therefore, the DMB user must update the service configuration information in order to receive the small broadcast service at the corresponding location, and the frequency must be scanned to update the service configuration information. However, there is a disadvantage in that the time required for scanning the frequency becomes long. Hereinafter, an embodiment in which service configuration information can be updated quickly will be described in detail with reference to FIGS. 6 and 7.

Referring to FIG. 7, the small broadcast service information providing unit 122 may include an FIB decoding unit 1220, FIG decoding unit 1221, FIG filtering unit 1222, a service information management unit 1223, and a service information configuration unit 1224. ), An FIB encoding unit 1225, an additional information FIG generation unit 1226, an FIC generation unit 1227, a service information FIG / FIB encoding unit 1228, and a barcode generation unit 1229.

The FIB decoding unit 1220 decodes the FIB data in the ETI frame and transfers each FIG to the FIG decoding unit 1221 and the FIG filtering unit 1222.

The FIG decoding unit 1222 interprets each FIG and delivers service configuration information in the multiplexed ensemble to the service information management unit 1223.

To the FIG filtering unit 1221 and the service information constructing unit 1224.

The FIG filtering unit 1221 reconfigures the FIGs by filtering the FIGs received from the FIB decoding unit 1220 so that service configuration information of the small broadcast service is not transmitted through the FIC. The FIG filtering unit 1221 transfers the reconstructed FIGs to the FIB encoding unit 1225. That is, the FIG filtering unit 1221 transmits the remaining FIGs except the FIG corresponding to the service configuration information of the small broadcast service in the FIG received from the FIB decoding unit 1220 to the FIB encoding unit 1225.

The FIB encoder 1225 encodes the reconstructed FIG and the FIG generated by the additional information FIG generator 1226 to generate an FIB, and transfers the generated FIB to the FIC generator 1227.

The additional information FIG generator 1226 generates a FIG including additional information and transmits the FIG to the FIB encoding unit 1225 in order to use the remaining space of the FIB due to the FIG filtered by the FIG filtering unit 1221. The additional information may mean separate regional information related to a small broadcast service such as limited reception information of a service or emergency message information related to a region, and information defined in addition to a separate standard may be used. This delivery of additional information may optionally be used.

The FIC generator 1227 generates an FIC by using the FIB received from the FIB encoder 1225, and transfers the generated FIC to the transmission frame generator 126.

The service reception information may include service configuration information in the received ensemble, service stream location of the subchannel for small broadcast service in the CIF, error correction code information, and the like.

The service information FIG / FIB encoding unit 1228 configures the service reception information generated by the service information configuration unit 1224 into FIG corresponding to the standard, encodes the FIG of the small broadcasting service, and forms an FIB for the small broadcasting service. Create For example, the service information FIG / FIB encoding unit 1228 may generate a FIB of FIG. 5 by encoding FIG. In this case, when the service reception information is encoded into the same type of FIB as the FIB transmitted through the FIC, functions after decoding the FIB in the process of decoding the FIC in the conventional broadcast signal receiving apparatus may be applied to the FIB for the small broadcast service. The same can be used. Therefore, in the embodiment of the present invention, it is also possible to provide reception information through a data configuration other than the FIB form, but if the service reception information is provided in the FIB form, the broadcast signal reception apparatus separately receives the FIB for the small broadcast service. There is no need to add the device.

The barcode generation unit 1229 receives FIBs composed of only information necessary for receiving a small broadcast service from the service information FIG / FIB encoding unit 1228 and receives broadcast transmission frequency information from the modulation and transmitting unit 128. The barcode generator 1229 generates FIBs and broadcast transmission frequency information as barcodes. The bar code may be any type of bar code, but the FIBs including the service reception information and the broadcast transmission frequency information may be sufficiently provided in binary form. For example, a two-dimensional barcode (Quick Response) code can provide up to 2953 bytes of information and has error correction. Therefore, a QR (Quick Response) code can be used as a barcode according to an embodiment of the present invention.

In addition, the service configuration information providing unit 122 may further include a service information providing server 1230.
