Bit rate Control

Defines the rate control method of this profile. There are two options:

 

Constant Bit Rate (CBR) or Variable Bit Rate (VBR). For CBR, the video

 

bit rate is between 24kbps and 320kbps. User can set the desired bit rate

 

to match the limitation of bandwidth. For VBR, user should choose the

 

quality level to set the video quality rather than bit rate. The quality level

 

is between 1 and 100. The higher value is the better quality.

 

 

Max Frame Rate

Defines the targeted frame rate of this profile. For example, set the frame

 

rate to 15 fps, then the image will be updated for 15 frames per second.

 

User can set the desired max frame rate versus video quality under the

 

limited bandwidth.
