    • PURPOSE: A system for driving a dual tuner is provided to prevent an oscillation component of a sub tuner from being induced into a main tuner. CONSTITUTION: When a frequency corresponding to a second input frequency signal belongs to a frequency band corresponding to a first input frequency signal, at least one sub driving unit(111) changes a frequency corresponding to the second input frequency signal to a frequency band range of a different level. The sub driving unit outputs at least one output frequency signal of at least one of a third output frequency signal and a fourth output frequency signal to a frequency band different from the frequency band range corresponding to at least one of the first output frequency signal and the second output frequency signal.

    • PURPOSE: A service link operation set up method in a digital audio broadcasting (DAB) system and a computer readable recording medium which records a DAB service link operation set up program therefor are provided to perform the service link operation set up quickly and accurately according to the search of service which will be linked quickly and accurately by one or more tuner in the DAB environment. CONSTITUTION: A control unit (21) extracts the frequency from the service link DB to perform the service link operation by a tuner (23), as a DAB terminal enters the feeble electric field of the DAB. The tuner scans the extracted frequency and the frequency which is currently being received. The tuner consecutively scans the frequency which is currently being received, and the effective frequency of one side which is mth close to the frequency which is currently being received. The tuner consecutively scans the frequency which is currently being received, and the effective frequency of the other side which is mth close to the frequency which is currently being received.

    • A digital broadcasting receiver and a one-touch channel setting method are provided to complete a channel setting process by inputting a command once, thereby increasing the user's convenience. Usable channel setting values by the combination of channel setting elements are calculated(210). Any one application value among the usable channel setting values is selected(220). A process for tuning a tuner corresponding to the application channel setting value with reference to the transponder list of a satellite corresponding to the selected application channel setting value is performed(230). When the tuning succeeds, a process for discriminating whether the tuned transponder signal corresponds to the predetermined signal information of the transponder corresponding to the satellite is performed(260). When the discriminating result is coincided with each other, an antenna and a tuner are set according to the application channel setting value(270).
