Choose “Constant bit rate” If the user wants to fix the bandwidth utilization

regardless of the video quality, choose “Fixed quality” and select the desired

bandwidth. The video quality may be poor due to the sending of maximal frame rate

within the limited bandwidth when images are moving rapidly. Consequently, to ensure

detailed video quality (quantization rate) regardless of the network, it will utilize more

bandwidth to send the maximal frames when images change drastically.

In JPEG mode, user can set “Maximum frame rate” and “Video quality” to adjust

the video performance.
