Abstract: A method and an apparatus for receiving broadcast data in a digital broadcast receiver are provided to decode the data correctly in spite of the broadcast data error or the bad receiving condition, and to reduce the standby power consumption. A point of time for starting the power-off mode is inspected in case of finishing the burst section. The receiving environment for receiving the broadcast data from the transmitter is inspected in case of the power-off mode section. In case of the good receiving environment, the critical value of the section interval is stored in the received burst section. In case of detecting the new first section, the section number of the detected first section and the detected time are stored. In case of detecting the second section, the difference of the clock number between the first section and the second section is calculated. The effectiveness of the calculated clock number difference is inspected. In case of existing the effectiveness, the number of the rest section is confirmed. The frame boundary expectation position is calculated by using the number of the rest section and the clock number difference. The time slicing is performed to the frame boundary expectation position.
