摘要

A terrestrial DMB receiver using an imaginary channel in a terrestrial DMB system is disclosed. The terrestrial DMB receiver includes: a key input unit for receiving an input from a user; a display unit for providing image output to the user; an imaginary channel storage unit for storing information on imaginary channels designated to each broadcasting service by the user; a DMB receiving unit for receiving terrestrial DMB broadcasting; a MCI/SI analyzer for analyzing MCI and SI of FIC information from a DMB broadcasting signal received through the DMB receiving unit; and a controller for searching for the imaginary channel storage unit according to values of number keys input from the key input unit, extracting service IDs, controlling the DMB receiving unit to select broadcasting services according to the extracted service IDs, checking the information analyzed through the MCI/SI analyzer, and performing an update for the imaginary channel storage unit.
