Abstract: An apparatus and method for receiving broadcast data in a portable digital broadcasting receiver. A Radio Frequency (RF) receiver receives a broadcast signal. A data demodulator demodulates the broadcast signal. Upon receipt of a broadcast-related key from a user, a controller controls the data demodulator to operate in a concentrated channel switching mode and acquire, from the broadcast signal, data of all broadcast channels including a broadcast channel selected by the user. Upon failure to receive broadcast-related key for channel switching for a predetermined time, the controller controls the data demodulator to operate in a selected channel viewing mode and acquire data of the broadcast channel selected by the user from the broadcast signal.
