11.2.6 Playback controls
1) Play speed control
This is to control the replaying speed. This speed control is applied only the Playing state.
The range is from x0.5 to x5.0. The speed is dependant on the system performance and load. The speed
value x5.0 is not the meaning of accurate 5 times high-speed replaying.
Figure 63 Play Speed Control
2) Play controls
These are to control the playing mode. The backward playing controls show only key frames. The video
encoding formats (MPEG4 and H.264) have Intra (key) frames. The image encoding format (MJPEG) has
only Intra (key) frames. Thus in the case of backward playing of MJPEG, it shows all frames. But the
others MAY be skipped.
The speed control is available only for the Forward playing mode.
The audio playing is available only for the Forward playing and x1.0 speed mode.
