Abstract: The present invention provides a method of processing data. The method of processing data includes receiving a broadcasting signal where mobile service data are multiplexed with main service data, extracting transmission-parameter-channel signaling information and fast-information-channel signaling information from a data group within the received mobile service data; obtaining first program table information describing virtual channel information of an ensemble and a service provided by the ensemble using the fast-information-channel signaling information, the ensemble the ensemble corresponding to a virtual channel group of the received mobile service data, obtaining information indicating that second program table information, which describes an additional service provided by the ensemble, is included in the ensemblem and parsing the second program table information according to the obtained information; and providing the additional service by using the second program table information.

Abstract: A digital broadcasting system and a method of processing data are disclosed, which are robust to error when mobile service data are transmitted. To this end, additional encoding is performed for the mobile service data, whereby it is possible to strongly cope with fast channel change while giving robustness to the mobile service data.
