Video Frame Rate
Video Display
Table 19: Ringtone
Configures video frame rate which needs to be adjustable
based on network condition. Increasing the frame rate will
significantly increase the amount of data transmitted,
therefore consuming more bandwidth. The video quality will
deteriorate due to packet loss if extra bandwidth is not
allocated.
Set the video display mode to:
● Original proportion
● Cut proportionally
