3.8.4. ROI
ROI means Region of Interest. Use this page to specify location of ROI windows. Only the
maximum resolution profiles can be defined as ROI. In this model, the default ROI windows are
profile 4 and 5.
To assign a name to the selected profile.
Video codec of the selected profile.
Resolution of the selected profile.
Assign the selected profile as a ROI stream or not. (Only available
for the profiles with max resolution)
Defines the rate control method of this profile. There are four
options: Constant Bit Rate (CBR), Variable Bit Rate (VBR),
Enhanced Constant Bit Rate (ECBR), and Enhanced Variable Bit
Rate (EVBR).
For CBR, the video bit rate is between low to high bandwidth based
on different resolutions. User can set the desired bit rate to match
the limitation of bandwidth.
For VBR, user should choose the quality level to set the video quality
rather than bit rate. The quality level is between 1 and 100. The
higher value can reach the better quality but of course will consume
higher bandwidth.
For ECBR, the video bitrates is based on normal CBR mode.
However, the target bitrates can be increased to max target bitrate
while lots of motion in video. The max target bitrates will keep a
pre-defined time period and then back to normal CBR bitrates.
For EVBR, the video bitrates is based on normal VBR mode.
However, the target bitrates can be increased to max target bitrates
while lots of motion in video. The max target bitrates will keep a
pre-defined time period and then back to normal VBR mode.
Defines the targeted frame rate of this profile. For example, set the
frame rate to 15 fps, then the image will be updated for 15 frames
per second. User can set the desired max frame rate versus video
quality under the limited bandwidth.
Defines the Intra/Inter-frame (I/P) ratio of this profile. For example,
set the GOP to 30, then the video stream will have one Intra-frame
every 30 frames.
