Setup-
ROI Encoding
Overview
- ROI (Region of Interest) Encoding function: the region specified by a ROI is encoded to transmit a relatively
good image compared to other regions.
[Enable] check the box for the activation.
[ROI Enable check box] select out of "ROI#1~4". The rectangular box in which you can specify the region
appears. Click and drag to adjust the position and size of the region. ROI # 2 ~ 4 activation is a useful feature
in NVC that support multiple regions.
[Sensitivity]
1~100 (The higher the value is sensitive.)
If the value is set to be about 50, you can see the difference in the eyes.
(Though the video bit rate is set to less than the recommended bit rate, the image quality of the ROI
designated region can be maintained.)
[OK button] click this button to apply the changed setting values.
Setting an example
- Condition: 1920x1080 resolution encoding, 1.5 Mbps network bandwidth
- Setting: setting the ROI to 1/4 of the entire image and the sensitivity to a value out of 40~60.
- Effect: The quality of the image set to the ROI is similar to the image transferred by the transfer rate "4Mbps"
(the default value of 1920x1080 resolution). You can also monitor the circumstances for the non-ROI part.
