Abstract

A digital broadcasting system and a data processing method are disclosed. In an aspect of the present invention, the present invention provides a data processing method including receiving a broadcast signal in which main service data and mobile service data are multiplexed, demodulating the received broadcast signal, acquiring demodulation time information of a specific position of a broadcast signal frame, and acquiring fast information channel (FIC) information representing binding information of a virtual channel in an ensemble and the ensemble of the mobile service data, acquiring a mobile service data frame of a specific virtual channel using the FIC information, and reference time information contained in a mobile service data frame, setting the reference time information to a system time clock at a specific time based on the demodulation time information and decoding the mobile service data according to the system time clock.
