A reserved recording method and apparatus of broadcast programs are disclosed. In setting reserved recording for broadcast programs, a start complementary time (SCT) and/or an end complementary time (ECT) are additionally set before a start time and after an end time of the broadcast programs, and if the SCT or a start time of a second broadcast program is ahead of the ECT of a first broadcast program, a switching time from the recording of the first broadcast program to the recording of the second broadcast program can be changed. Thus, a failure to record a portion of a broadcast program previously reserved for recording due to a delay in a broadcast time or the like can be prevented.
