MJPEG
JPEG (M-JPEG or MJPEG) is a video compression format in which intraframe coding
technology is used. Images in a MJPEG format is compressed as individual JPEG images.
This means that under the same bitrate, the more complex the is, the higher the
quality of the image is, and the requirement for network bandwidth is also higher.
4.1.8 Smoothing
It refers to the smoothness of the stream. The higher value of the smoothing is, the
of the stream will be, though, the video quality may not be so The lower value of the
smoothing is, the higher quality of the stream will be, though it may appear not
4.2 ROI
ROI (Region of Interest) encoding helps to discriminate the ROI and background in
video compression. The technology assigns more encoding resource to the region of interest, thus
to increase the quality of the ROI whereas the background is less focused.
4.2.1 Set ROI
ROI (Region of Interest) encoding helps to assign more encoding resource to the region of interest,
thus to increase the quality of the ROI whereas the background is less focused.
Before You Start
Please check the video coding type. ROI is supported when the video coding type is H.264 or H.
265.
