can reduce the amount of bandwidth required per user while maintaining a minimum limit
on the user experience.
Note: This example uses the Administration Web Interface for configuring the Portal for
Minimum Image Quality and Maximum Initial Image Quality. The Portal OSD may
also be used to configure the Portal. See Section 2 On Screen Display (OSD) for the
corresponding OSD functionality. The Maximum Initial Image Quality does not have a
corresponding parameter on the Portal OSD; it is intended as an administrator-only
parameter due to the impact on network traffic.
1. Open the Portal Administration Web Interface for the first user’s Portal by using an
internet browser to open the Portal IP address
2. Log in to the Portal Administration Web Interface
3. Select the Image webpage from the Configuration menu

4. Slide the Minimum Image Quality slider to the right
5. Slide the Maximum Initial Image Quality slider to the left
6. Select the Apply button to accept the changes
7. Repeat for the other three user Portals
The Minimum Image Quality is now configured towards Perception-Free to increase the

The Maximum Initial Image Quality is now configured towards Reduced to limit the quality
on the changed image (i.e. initial video frame). A lower Maximum Initial Image Quality
setting requires less bandwidth as the lower-quality initial image will require less
bandwidth to create. In this case, the administrator and the users determined that setting
