ABSTRACT:
A digital broadcast receiver and a control method thereof are disclosed. The control method includes receiving a broadcast signal into which mobile service data and main service data are multiplexed, extracting TPC signaling information and FIC signaling information from a data group in the received mobile service data, acquiring a program table describing virtual channel information and a service of an ensemble, using the extracted FIC signaling information, the ensemble being a virtual channel group of the received mobile service data, detecting a conditional access descriptor indicating whether the mobile service data was encrypted, using the acquired program table, and controlling such that the encrypted mobile service data is decrypted, using information of the detected conditional access descriptor.
