Abstract:
The present invention relates to data application technologies in the field of video surveillance, and discloses an intelligent playback method for video records based on a motion information and an apparatus thereof. The method comprises the following steps: searching for all motion detection additional information conforming to a time period of a playback request in a hard disc, and storing the motion detection additional information as a motion information in a motion information linked list in terms of a time sequence; obtaining a current playback mode and a current playback time, and looking up a nearest motion information under the current playback mode and the current playback time from the motion information linked list; matching the found nearest motion information with the current playback time; controlling a playback speed according to a matching result, so as to implement an automatic control of an intelligent playback speed. A real-time, automatic, continuous control of a playback speed can be implemented by repeating performing the above steps, so that automatically adjusting to a normal playback speed when there is motion data and automatically adjusting to a rapid playback when there is no motion data are implemented, and a playback time of video records can be reduced.
