DIGITAL BROADCASTING RECEIVER AND METHOD FOR CONTROLLING THE SAME

摘要

A control method of a digital broadcast receiver comprises the following steps of: 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 first program table describing virtual channel information and a service of an ensemble by using the extracted FIC signaling information wherein the ensemble is a virtual channel group of the received mobile service data; detecting a control access descriptor indicating whether the mobile service data has been encrypted by using the acquired first program table; and controlling the encrypted mobile service data to be decrypted by using information of the detected control access descriptor.
