摘要： Disclosed is a system and method for efficiently providing Electric Service Guide (ESG) data in a Digital Video Broadcasting-Handheld (DVB-H) system. There is presented a method for dividing ESG data into basic data and additional data and for separately providing the data, wherein the basic data is necessary to provide a DVB-H broadcasting service. To separately provide the basic data from the additional data, a service provider forwards, during a basic profile session, only the basic data necessary to provide a broadcasting service, and separately forwards additional data during an advanced profile session including additional and high-grade data. Then, a terminal determines if a profiling is set up. If the profiling is set up, the terminal gets access to the basic profile session to acquire the basic data, and deals with the advanced profile session as a background job. As a result, the terminal first gets the basic ESG data necessary to provide the broadcasting service, which can antedate the commencement of the broadcasting service, and which can improve the effectiveness of a data receiving scheme of the terminal in great measure.
