摘要

A broadcast receiver, a Forward Data Channel (FDC) interface method, and a broadcast signal processing method are disclosed. The Forward Data Channel (FDC) interface method includes: requesting a tuning of a Forward Data Channel (FDC); receiving data of the Forward Data Channel (FDC) tuned/demodulated by the request, and specific information indicating the presence or absence of validity of the FDC data; and performing an error correction decoding process, if the demodulated data is valid by referring to the specific information indicating the validity.
