A method to receive a broadcast includes parsing a first trigger for obtaining a first identifier for identifying a targeted Triggered Declarative Object (TDO), and a preparation trigger time for the targeted TDO; parsing a second trigger for obtaining an activation time and a termination time for the targeted TDO; activating the targeted TDO corresponding to the first identifier on a background, when a receiving time of the preparation trigger is before the preparation trigger time, immediately activating the targeted TDO corresponding to the first identifier on the background, when the receiving time of the preparation trigger is after the preparation trigger time; changing a state of the targeted TDO to a foreground, when a current system time is after the activation time; and terminating the targeted TDO, when the current system time is after the termination time.
