8.4.3 Configuring ROI Encoding
ROI stands for the region of interest. And the ROI encoding enables you to discriminate the ROI
and background information in compression, that is to say, the technology assigns more encoding
resource to the region of interest to increase the quality of the ROI whereas the background
information is less focused.
Step 1 Enter the ROI settings interface: Configuration > Advanced Configuration >Video / Audio
