ABSTRACT:
An apparatus and method for supplying information so that power consumption in a digital broadcast receiving terminal can be reduced and a user can use an appropriate antenna depending on a situation. The digital broadcast receiving terminal includes an external antenna detachably assembled with the outside of the terminal a switch unit for selecting any one among the internal antennas and the external antenna, and a signal-receiving condition sensing unit capable of sensing the signal-receiving condition of the internal antennas and the external antenna. If it is impossible to receive the digital broadcast signal by using the internal antennas, the external antenna is used. If the external antenna is mounted, power is supplied only to an RF unit connected to the external antenna and the power supply to the remaining RF unit is cut off, reducing power consumption.
