storing, at a memory unit, the extracted service information and the extracted identifier;
displaying, at a display device, a screen image configured to facilitate a search of one or more of the received broadcasting programs;
receiving, at an input unit, an input or a selection of the program characteristic from a user via the display device;
searching, at a searching unit, at least the stored service information or the stored identifier based on the received input or the received selection of the program characteristic in order to generate a list of broadcasting programs corresponding to the received input or the received selection of the program characteristic;
providing the list to the display device for display at the display device;
receiving, at the input unit, a selection of a broadcasting program from the displayed list of broadcasting programs;
switching, at a switching unit, to a broadcasting channel corresponding to the selected broadcasting program; and

Abstract
A digital multimedia terminal comprises a receiving unit to receive a broadcasting signal. The digital multimedia terminal also comprises an input unit adapted to receive input associated with a user preferred program characteristic. The digital multimedia terminal also comprises a controller, operatively coupled to the receiving unit and the input unit, adapted to extract program information from received broadcasting signals and to search extracted program information based on the user preferred program characteristic. The digital multimedia terminal may further comprise a display unit, operatively coupled to the controller, adapted to display program description information associated with the extracted program information that corresponds to a broadcast program having the user preferred program characteristic.
