Digital broadcast signal and method and apparatus of processing for the digital broadcast signal

A digital broadcasting signal and a method and an apparatus for processing the digital broadcasting signal are provided to allow a receiver to determine whether channel data corresponds to an updated version or data erroneously transmitted from a broadcasting station. A digital broadcasting signal includes a master guide table(MGT) and a rating region table(RRT). The MGT includes restricted information about the version of the RRT. The restricted information includes the information about the version of the RRT and time information for update. The restricted information is defined by using a global positioning system(GPS) unit. The restricted information is defined according to a year, a month, and a day. The restricted information is defined by using a reserved field in the MGT and descriptor information.
