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.

Abstract: Methods and apparatus for optimizing idle mode stand-by time in wireless device operable in a multicast system are disclosed. In order to maximize or optimize the stand-by time for idle mode, a time line for decoding of overhead information symbol (OIS) data received in one or more superframes in the wireless device. Based on the determined time line, an offset time period can be determined for setting an idle mode timer period used by the wireless device to decode the OIS information. By offsetting the timer period, a wireless device can be ensured to wake up and prepared to latch OIS information before the start of a superframe boundary, thus minimizing the wake up time of the device operating in an idle mode and, in turn, optimizing stand-by time.
