Abstract
A digital broadcasting system and a data processing method are disclosed. A data processing method of a digital broadcasting receiver comprises receiving a mobile/handheld (MH) broadcasting signal including mobile service data and main service data; generating a RS (Reed-Solomon) frame from the received MH broadcasting signal; extracting control data from the RS frame, the control data including charge adjustment information required to use a service provided by at least one service provider, the service being encrypted; determining whether the service is available, by comparing the extracted charge adjustment information with balance information written in the smart card; controlling the second RS frame using the control data so that an encrypted service of the second RS frame is decrypted, if the service is available; and mapping the extracted charge adjustment information with a corresponding service provider and storing the information.
