  • the video processor 9400 can define a part of the video being recorded as a snapshot, where the snapshot is associated with the received event.
  • the part of the video which is defined as the snapshot can be a single frame of the video.
  • a frame of the video is one of the many still images which compose the complete moving picture of the video.
  • a typical number of frames per second in digital videos is 30. However, higher or lower numbers can be found in current digital video cameras.
  • the snapshot may be defined as being a number of frames, which are associated with the point in time when the event is received. For example, all frames that relate to one second of the recording time of the video define the snapshot. In this case a snapshot does not relate to a single still picture but to a short moving picture sequence being composed of a couple of frames in a respective recording time interval, which is short enough to define the snapshot associated with the received event.
