The Encoding page is used to configure various encoder settings.
9.1 Encoding Settings
9.1.1 Encoder Connection Parameters
Once a connection is made, you can dynamically optimize the video quality by adjusting the connection parameters.

High Compression 6 0-10
AVOption Both Audio, Video, Both
FrameRate Divider 1 1-256
Min Refresh 10 0-255 (Hz)
Max Refresh 30 0-255 (Hz)
Color Sampling 4:2:2 4:2:2, Static 4:4:4, Dynamic 4:4:4
Allow K/M Switch No Yes, No
K/M Idle Limit 5 3-30 (s)
Table 9-1: Default/Valid Encoder Connection Parameters
l Max Bandwidth: Enables you to specify the maximum bandwidth the connection can utilize (Mbps)
l Frame Rate Divider: Allows you to specify the fraction of video frames the encoder processes
For example, if the input video has a refresh rate of 60, a value of 3 in this parameter will make the system process
at most 20 frames per second, so flow control will not be necessary as long as the maximum bandwidth is
sufficiently high to accommodate 20 frames per second
l Low Compression: Allows you to control the amount of compression applied to portions of the input video where
the image is static or has very little motion (e.g. mouse cursor moving). Values between 0-7 are recommended for
the best visual results. Higher values (8-10) are recommended for networks with bandwidth constraints
l High Compression: Allows you to control the amount of compression applied to portions of the input video where
the image is detected to be dynamic. Values between 0-7 are recommended for the best visual results. Higher
values (8-10) are recommended for networks with bandwidth constraints
l Min/Max Refresh: The encoder continuously sends updated video information to connected clients. Only small
sections of the screen are sent for every video frame, and over a period of time, the whole screen is completely
