Step S302 classifies record task according to the record task time parameter.
Two main time parameters in the record task: video recording duration, video recording rollback duration.The video recording duration is the time period length that record task is carried out, and video recording rollback duration is a video recording content time span.According to these two parameters, record task is divided three classes: record task classification one, the record task of record task duration only is set, abbreviate regularly video recording as; Record task classification two only is provided with the record task of video recording content duration, abbreviates the rollback video recording as; Record task classification three is provided with the record task of task duration and content duration simultaneously, and abbreviating as regularly, rollback mixes video recording.
Step S304 is according to the overlapping situation combined picture-recording task of video recording.
The overlapping situation of recording a video specifically can be divided into following four classes:
Overlapping situation 1: regularly video recording is regularly recorded a video overlapping with another.

Fig. 8 illustrates the schematic diagram of combined picture-recording example in accordance with another embodiment of the present invention.With reference to Fig. 8, this embodiment may further comprise the steps:
Step S802:, record task is classified according to the time parameter of record task.
For example, A record task video time be AM08:00 to AM09:00, then A video recording is a regularly video recording, the record task duration is 60 minutes.
B record task video time is not for limiting, and video recording content duration is 10 minutes, and then the B video recording is rollback video recording, and video recording content duration is 10 minutes.
The video recording duration of C record task be AM10:00 to AM11:00,60 minutes, video recording content duration was 10 minutes, then the C record task be one regularly rollback mix video recording, record task duration 60 minutes, video recording content duration 10 minutes.
Step S804: according to record task type and video recording combined strategy combined picture-recording task.
With reference to Fig. 9, the concrete video recording combination of this embodiment is as follows:
Timing record task one: video time is: PM21:00 to PM22:00, duration 60 minutes.Timing record task two: video time is: PM21:30 to PM23:00, and duration 90 minutes then makes up two record task, and video time is: PM21:00 to PM23:00, duration 120 minutes.
