The jog/ shuttle knob, shown in the figure below, is a combination
of a shuttle ring with an embedded jog disk, which is used to
provide wide range in playback control. Note that the jog/ shuttle
knob is active only when the DVR unit is in Playback mode.
While playing back video, you can use the shuttle ring to select
different speeds of forward and backward playing. Rotating the
shuttle ring causes the unit to playback in fast forward/ backward
playing speed. According to the angle you rotate the shuttle ring,
you can choose the playing speed from 1Ч, 2Ч, 4Ч, 8Ч, 16Ч, and
32×, in both forward and reverse directions, shown in the figure
below:
Inside the shuttle ring is the jog disk, shown in the illustration
below, it can be turned completely in either direction. Once you
freeze the video, you can use the jog disk to go to single-step
play back. Clockwise rotation causes forward one-step playback;
and counterclockwise rotation causes backward one-step
playback. This is for JPEG recoding only.
