Claim 4:
5. The method according to claim 1, wherein detecting the voltage drop of the battery of the remote controller in a standby mode further comprises:
sampling the voltage of the battery of the remote controller within a time period from a sampling start time t1 at a first preset sampling interval t2 in the standby mode;
if no voltage drop is occurred in the sampled voltages, sampling the voltage of the battery of the remote controller within a next time period from a next sampling start time t3 at the first preset sampling interval t2 in the standby mode until a voltage drop is occurred, wherein the next sampling start time t3 is (t1+T+Δt1), where T is a time period of the voltage of the battery of the remote controller, and Δt1 is a first time period;
determining an appearing time of the voltage drop in the sampled voltage t4 in the time when the voltage drop is occurred;
sampling a subsequent voltage of the battery of the remote controller from a start time t5 at a second preset sampling interval t6 in the standby mode to form a plurality of samples until the number of the samples is N, wherein the start time t5 is equal to a total of the appearing time of the drop in the sampled voltages t4 and the second preset sampling interval t6, the second preset sampling interval t6 is equal to a total of the time period T and the second time period Δt2, N is a positive integer, and a product of (N−1) and the second time period Δt2 is greater than or equal to the appearing time period of each of the voltage drops in the voltage in the samples, wherein the second time period is less than the first time period.
