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.

Description

technical field

[0001] The present invention relates to a digital broadcasting system, and more particularly, to a digital broadcasting receiving system and a method for controlling the digital broadcasting receiving system. Background technique

[0002] The digital broadcasting system consists of a digital broadcasting sending system (or transmitter) and a digital broadcasting receiving system (or receiver). In addition, a digital broadcast transmission system digitally processes data such as a broadcast program, and transmits the processed data to a digital broadcast reception system. Due to various advantages of the digital broadcasting system, such as efficient data transmission, the digital broadcasting system is gradually replacing the conventional analog broadcasting system.

[0003] However, a vestigial sideband (VSB) transmission mode adopted as a digital broadcasting standard in North America and Korea is a system using a single carrier method. Therefore, in a ba...
