摘要

A method for controlling a table related to the broadcasting program rating information of a PSIP(Program and System Information Protocol) in digital broadcasting, a broadcasting signal including the data structure of the table, and a receiver for processing the same are provided to classify a fixed RRT(Rating Region Table) and a downloadable RRT and determine whether the fixed RRT or the downloadable RRT is received, thereby operating the broadcasting program rating system more quickly and improving the efficiency of memory use. A method for controlling a table related to the broadcasting program rating information of a PSIP(Program and System Information Protocol) in digital broadcasting comprises the following steps of: adding a fixed RRT(Rating Region Table), at least one or more information for separating a downloadable RRT or information for additionally defining the version number of the downloadable RRT to a RRT or an MGT(Master Guide Table)(S608); and transmitting the RRT or the MGT, to which the fixed RRT, at least one or more information for separating the downloadable RRT or information for additionally defining the version number of the downloadable RRT are added, to a broadcasting receiver.
