A digital multimedia broadcasting terminal is provided to use only one power supply source for each block and distribute the power to each block by means of a switching device. A core block(40) is operated at the start state of a terminal. An LDO(Low Drop Output voltage regulator)(10) supplies the power to the core block. A digital block(50) is driven at the waiting state of a communication service. An analog block(60) is operated when receiving the DMB data according to the DBM service and when displaying broadcasting contents corresponding to the DMB data. The DMB terminal includes the first switch(20). The first switch is driven so that the power is supplied to the digital block. |
