DIGITAL BROADCASTING SYSTEM AND METHOD OF PROCESSING DATA IN DIGITAL BROADCASTING SYSTEM

摘要

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 ensemble and parsing the second program table information according to the obtained information; and providing the additional service by using the second program table information.

1. A method for transmitting broadcast signals, the method comprising:
FEC (Forward Error Correction) encoding broadcast service data for a broadcast service; encoding the FEC encoded broadcast service data using a specific code rate; encoding transmission parameters including information specifying the specific code rate; generating data frames including the encoded broadcast service data and the encoded transmission parameters; and transmitting the broadcast signals including the data frames, wherein the broadcast signals further include service acquisition data including information to enable service acquisition, wherein the broadcast signals further include service information data describing the broadcast service, wherein the service acquisition data further include version information specifying a version of a protocol for the service information data, wherein the service acquisition data further include major channel number information specifying a major channel number of the broadcast service, and wherein the service acquisition data further include minor channel number information specifying a minor channel number of the broadcast service.
