8.3 Configuring ROI Encoding

Purpose:
ROI (Region of Interest) encoding helps to discriminate the ROI and background information
in video compression, which means, the technology assigns more encoding resource to the
region of interest, thus to increase the quality of the ROI whereas the background information
is less focused.
ROI function varies according to different camera models.
